Factors Affecting Software Resiliency

The digital transformation is happening everywhere right from small private firms to government organizations. On the personal front, connected things is coming on, where by every thing that we have or use will be smart enough to connect and communicate with other things(systems). This in effect means there will be an increased reliance on IT systems to accomplish various tasks. This will call for high order of resilience on the part of such systems and the absence of which may lead to disasterous situation.

As we all know, the word resiliency means 'the ability to bounce-back after some events'. In otherwords, it is a capability of withstanding any shock or impact without any major deformation or rupture. In software terms, resilience is the persistence of the avoidance of failures when facing a change or in a deviated circumstance.

To design a resilient system, one should first understand the various factors that work against the resiliency. Here are some such factors:

Design Flaws

Design and Architecture of the systems is a major factor that works in favor or against the resiliency requirement. The architects shall while designing the system or solution should have a good understanding of what could go wrong and provide for an exception handling ability, so that all exceptions are appropriately handled, making the system not to go down and instead recover from such exception and continue to operate. The architects have many options today in terms of tools, technologies, standards, methodologies and frameworks that help buidling resiliency within. It is the ability of choosing the right combination of tools, technologies, etc for the specific systems that will decide on the resilience capability of the system. 

Software Complexity

The size and complexity of software systems is increasing, thus the ways in which a system can fail also increases. It is fair to assume that the increase in failure possibilities does not bear a linear or additive relationship to system complexity. Typically, the complexity of the software systems increases as it evolves by responding to the changing business needs. This is more so as the tools and technologies used to design and build the software are becoming outdated, making it difficult in maintaining the systems. 

This complexity attribute makes it increasingly difficult to incorporate resiliency routines that will respond effectively to failures in the individual systems and in their complex system. The cost of achieving an equivalent level of resiliency due to the complexity factor should be added to that of the individual systems

Interdependency and Interconnectivity

We are living in a connected world and systems of many of today's businesses depend on connectivity with their partner entities to do their business. This adds multiple points of failures over and above the network connectivity. The system resiliency is increasingly dependent on the resiliency of systems different other organizations over which the entity has no control. This means that a failure or outage of a business partner's system can have a ripple effect. This situation requires the systems need to be aware and capable of such failure or outage with other connected systems and the ability to recover from such events should be designed within. 

Rapid Changes

Thanks to the evolving digital economy, the business needs are changing too frequently and thus needing system changes. Every change in an existing system, for sure will add a bit of complexity, as the architecture on which the system originally designed wouldn't have considered the changes that are coming through. Many a times, considering the time to market, such changes need to be implemented quicker than expected, leaving the software designers to adopt a quick and dirty approach to deliver the change, leaving a permanent solution for a later time period. The irony is that there will never be a time when the 'permanent solution' is implemented.

Change is one of the key source of adding complexity to the Software systems. However, the evolving tools, technologies and methodologies come to the rescue, so that the Architects design systems and solutions in such a way to pave way for embracing such changes and to embed the resiliency factors in the design.

A frequently held criticism of Common Criteria testing is that, by the time the results are available, there is a good chance that the tested software has already been replaced. The danger here is that the new software may contain new vulnerabilities that may not have existed in prior versions. Thus, determining that an obsolete piece of software is sufficiently resilient is not particularly indicative of the state of the newest version and, therefore, is not very useful

Conclusion

Higher levels of resilience can be achieved by leveraging Machine Learning and Big Data tools and techniques. As the world is moving towards more and more connected things, high order of resilience is critical. With Machine Learning capability, the systems and devices can be embedded with algorithms that make them learn from past events and the data collected from various other connected networks and systems in addition to the ambient data. The systems can be designed to predict the health of various underlying components and thus its own health as well. Based on such prediction, the components may choose to use alternate approaches, like using alternate network protocols like Wireless, Bluetooth, etc, or choose to connect to a different component or system altogether.

Evolution of Wearables - What is in store?

Many of us are hearing more and more about fitness bands and some are using these. Big players are now rolling out smart watches, which has disrupted the basic fitness bands considerably in a very short span of time, as these smart watches have these basic fitness features within. Wearables like, glasses, jewellery, headgear, belts, armwear, wristwear, legwear, footwear, skin patches, exoskeletons and textiles, etc are also increasingly becoming "Smart". These emerging smart devices can be worn by human beings, which will collect various data based on embedded sensors and provide useful information that will help improve oneself, which could be on physical fitness, health, etc.

As one can understand, wearables is not just limited to the gadget that decorate your wrist and the number of wearable devices in different segments are growing very fast. With rapid evolution around this space, there are devices that are worn around different areas of the body and the following graphic shows the smart devices that are worn in different parts of the human body:

Who are at it?

Amongst many others, companies like Google, Samsung, Fitbit, Jawbone, GoQii, LG, Sony have been into Wearable devices and the competition is heating up as big players like Intel and Apple are betting big on this market.

Fitbit dominated the market for “basic bands,” according to Canalys’ market estimates, with more than 50 percent market share in the second half of the year. The Jawbone UP came second, cutting itself around a fifth of the pie, followed by Nike with its Fuelband.

The market forecast and the trend makes us feel that this wearable space could potentially disrupt many of the traditional devices. Thus many are looking at embracing this market either to see how this could disrupt their product line or to see if they have an opportunity in this space.

NeuroMetrix of Waltham will be jumping into the market for wearable electronic devices. But the company's new Quell device - an over-the-counter version of its Sensus device for management of chronic pain - is an actual medical device that is used to manage pain.

TomTom, the Dutch brand known for its standalone GPS navigators among other things, has brought its line of sports watches to India. TomTom launched four fitness wearables, which include TomTom Runner and Multi-Sport GPS watches, which deliever real time stats such as time, distance, pace, speed and calories burnt to runners, swimmers and cyclists.

Xiaomi said in a press release that local sales of its Mi Band - a fitness tracking bracelet that can be powered for 30 days on a single charge, has surpassed 100,000 units since it was unveiled. The Beijing-based company forecast that more than 500,000 Mi Bands will be sold in Taiwan by the end of the year, giving it the biggest share of the country's wearable device market that is currently led by Sony Corp. and Samsung Electronics Co.

Intel is firing on all cylinders to expand into the growing wearable technology arena such as smart watches and other Internet-enabled wearables. This investment in Vuzix Corporation is yet another effort by the chipmaker in this regard. Intel has unveiled Curie, a low-powered module no bigger than a button, as part of its vision to lead in the wearables field.

Rumors have said that HTC will be launching a smartwatch at the upcoming CES. The initially planned unveiling of the device was back in October, but the date was pushed back to CES 2015. Details of the device are unclear though, as it could be a smartwatch or a fitness tracker.

In addition to all these devices, there will also be wearable technology focusing on health and fitness, prosthetics and smart clothing.

The Trend

Shipments of smart wearables are expected to grow from 9.7 million in 2013 to 135 million in 2018, according to CCS Insight's new global forecast. The forecast predicts that wrist-worn devices will account for 87% of wearables to be shipped in 2018 — comprising 68 million smartwatches and 50 million smart bands with no screen or with a minimal, one-line display.

The smartwatch will be the leading product category and take an increasingly large share of wearable shipments. We estimate smartwatch shipments will rise by a compound annual rate of 41% over the next five years. Smartwatches will account for 59% of total wearable device shipments this year, and that share will expand to just over 70% of shipments by 2019.

The dominant sector will remain the healthcare sector which merges medical, fitness and wellness. It has the largest number of big names such as Apple, Accenture, Adidas, Fujitsu, Nike, Philips, Reebock, Samsung, SAP and Roche behind the most promising new developments.

Google's Android could be critical for developing the smart devices ecosystem, though significant changes will be required before it is suitable for all kinds of wearable devices. Google has already released Android Wear, targeted for smart watches.

Samsung, Google, Apple, with their massive war chests, have come into this market. They’re going to really help elevate the category for consumers. They’re going to help people understand the kinds of benefits that they can get from these products. The next few years, will see activity trackers with a little bit more biosensing data, and smart watches that people are going to have to charge every night.

If Wearables 1.0 was about creating the basic technologies for the wearable devices, Wearables 2.0 was and still is about crafting rich, robust business models based on these technologies. Wearables 3.0 will be all about perfecting, expanding and engaging customers at a level never experienced before. Big players in Wearable Technology and Internet of Things, from healthcare companies to insurance corporations, from high street retailers to music industry, Google, Apple, Samsung, Mercedes, Nike, Audi, just to name a few are all to give for free their devices in exchange for data.

What could be the future?

Though it’s easy to be pessimistic, one cannot ignore the potential that this market has in store. In any event, while we wait for this category to evolve, it’s entertaining to watch the puzzle pieces slowly come together. Convergence is expected, in much the same way that the smartphone extended the basic functionalities of the feature phone and disrupted certain traditional devices like point and shoot camera.

Medical and Wellness segment could be the one which will embrace this category of wearable devices and make health more affordable and self manageable for every one. For instance, one can wear a virtual doctor while on a specific treatment. A better example could be that the advances in wearable devices could lead to a scenario, where a diabetes patient may get appropriate doses of insulin administered into his body automatically based on various data collected by the sensors worn around the body. This could be risky, if the data, so collected are inaccurate and that is one of the major concern that is expected to be addressed in the coming years.

There has to be a marriage of fitness devices and medical management devices to really impact patient health. The future of wearable technology in fitness and health isn’t about the fitness bands and health monitors – it’s about what can be done with the data they collect, which means that these devices have to be supplemented by smart applications that are powered by big data and analytics tools.

A very large percentage of the population already owns a smart phone, which has lot many capabilities, including that of the basic wearable devices. As such, it will be critical that wearables provide a distinct value proposition that is separate and different than the smartphone, although the smartphone will likely still act as the “hub” to collect information.

We’re already starting to see sensor-embedded running vests and smart socks. But we could soon see jackets with solar panels (to recharge your gadgets on the go), 3D printed dresses that everyone can afford, health-monitoring underwear, even clothes that react to light. If we had the ability to change the look of all of our clothes, just by fiddling with our phones, it would mean less spending on new gear and plenty of spare wardrobe space.

Wearables need to move beyond the gamification of fitness to focus on monitoring and improving our health. With extra sensors and smarter and reliable algorithms, future devices should be able to warn us of high blood pressure and dehydration, fatigue and stress. Perhaps then, forewarned by data we understand, we’ll find wearables more compelling.

In Wearable Tech 3.0 Security is paramount. Six months from now and we’ll understand how poor the wearables 1.0 security was, if any! The big players in this market should finally draw, define and release the IoT and Wearables industry Security Standards. Wearable Tech 3.0 is the beginning of a new era where enterprises provide real value to their customers, a key technology benefit in the age of the customer.

Internet of Things: What Strange Things Can Happen

It was about 6 years back, by when we have started to see WiFi enabled digital cameras and we were wondering what this has to do in a digital camera. But with that, the digital cameras were able to upload the captured images automatically to the cloud based photo albums. Later came in GPS equiped digital cameras, which attaches the location to the captured images. Of course, with smart phones equiped with higher resolution cameras, the digital cameras are on the downfall. That is just a well known example of how a 'thing' or a smart thing can connect to a network and share useful data for a purpose. So much have evolved since then and we now see a world of possibilities to have all the 'things' connected.


Researchers see a lot of benefits by making things smart and inter-connecting them. The networking technologies are also evolving at a brisk pace, offering various improvements over the wireless technologies and protocols. We can see this trend advancing further and may mature in about two decades from now. Looking further, in line with my blog on Human Interface Technology, even humans can remain connected, and that will render human disabilities a thing of the past century.


If you followed this year’s CES, it is evident that the future is all about connected devices. We could see everyday devices equipped with sensors and connectivity to work together, understand what we’re doing, and operate automatically to make our lives easier. Here are some of real world examples of Internet of Things:


A smart refrigerator that can read the embedded tags on the grocery items that are stored in it and then using the supported backend platform on the cloud, identify the items and fetch its details as to date of manufacture, expiry date, quantity, etc. Thus the fridge may alert the consumers about the state and stock of such items. With the kind of wearable gadgets that we see now, these alerts can be through such devices too. It is left to your imagination to what extent this smart capability can be extended.


Medical and emergency care is another area where the smart 'things' play a very useful and life saving role. For instance, a connected car can call emergency services faster than a mobile phone. Again, with the help of embedded or worn smart gadgets, the hospital can get to know the patient history as the patient gets into the hospital and can get ready for the emergency services thereby saving precious time, which can be life saving. Check out this interesting video. Check out this video that IBM has made out describing how it is growing fast and could invade into the everyday life of human beings.


Extending this further to the daily routines of a business executive, the possibilities are endless and here are some that are close to reality, if not already real:

• Your smartphone once it hears a hint about a meeting in a conversation, it will in the background look up your calendar and will pass on the busy / free information. If the executive uses a glass, then he would be seeing the schedule as he talks and thus facilitates the scheduling of the meetings.
• The smart alarms will be smart enough to consider information as to what time did go for sleep, the schedule (both personal and official) for the following day and thus will intelligently decide the wake up time in the morning and triggers the alarm.
• Depending on the traffic conditions, your car will intelligently suggest alternate routes to reach the office or such other scheduled meeting venue and if needed, automatically inform the meeting organizers about the possible delay or may seek rescheduling of the meeting.
• As you drive back home, you just remember that you need to pickup some drugs from a drugstore. Your smart car will already know this and will identify a store that stocks the drugs that you need and that is on the route or closer to the route that you drive. It can even place the order with the store and let the store keep your items ready for delivery and you just need to pick up enroute.
• Needless to say, your car will be smart enough to perform a health diagnostics of itself and will decide on a best date for its own garage visit so that your schedules are not impacted.
• These smart things will know about your presence and which device is in touch with you to send out alerts. For example, if you are at home watching TV, you may see your TV showing alerts from your washing machine and similarly, when you are at work, your smartphone would be used to show these notifications.
• Here are some more ways the 'Internet of Things' can impact your daily life.

Coming back to the household, you are watching your favorite action movie with surround sound and you did not changed your smartphone from a silent mode back to a ringing profile. You don't have to worry, your smartphone knows what you are upto and over a period would have learnt by itself, as to which of the calls you would want to answer at this situation and accordingly either rejects the call by answering the caller appropriately. If it is an important call that you would n't want to miss, it knows it already and will tone down the TV audio volume and thus draws your attention to the call and you don't have to reach out to your phone, your TV will take over the call from your smartphone. To extend this further, depending on the profiles of other members at the house, which the house already knows through its sensors and networks, your smart phone will decide whether to route the call on to the TV or not.


We can now visualize the possibilities and it is endless. The smart things will have built in learning capability and will keep learning from its master's behavior to perfect its services. This trend will lead us to a situation where the things might by themselves or under the influence of hackers attempt to take over human beings as portrayed in some of the recent science fiction movies. On top of this, hackers will also be leveraging these smart abilities to hack into these connected networks and could do whatever they have been doing with the connected systems now.


Here is how the hackers can intrude into your digital lifestyle:

• We have already seen reports of a smart refrigerators sending out spam emails.
• By hacking into your house network, hackers may get to know how many members are home or if there are none inside the home, which information will be useful for them to plan their burglary attempts, etc.
• Your TV may refuse to play your favorite channel and will rather play content that the hackers prefer you to watch.
• Your car may drive to a place that is different than where you wanted to visit. On the same lines, hackers can execute traffic diversions and cause traffic jams as portrayed in the movie Die Hard 4
• All your orders for home supplies may be hacked and deliveries may happen elsewhere, while you would have paid for it. And of course, your house network will still acknowledge for having received the deliveries, while it is not actually.
• The impact of hacking into the emergency service network could be huge and life threatening.
• Your smartphone can be hacked to refuse critical business calls and thus causing revenue impact to your organization.

IDC anticipates that more than 200 billion connected devices will be in use by 2021, with more than 30 billion being autonomous devices. Cisco’s Internet Business Solutions Group (IBSG) predicts some 25 billion devices will be connected by 2015, and 50 billion by 2020. How will having lots of things connected change everything? Find the answer in the infographic. With all this, Internet of Things is coming and will be here to stay soon. Whether we, the humans are ready to take on this evolution remains to be seen.

Human Technology Interfaces - What The Future Has In Store

All of us would have been reading something or other on technology advancements that work with human body. For example, we have Health IT companies experimenting embedding memory chips under the skin of human body to store the individual's health records, so that when you walk into clinic, the clinic will get to know about your health history and would be able to suggest the further course and all this can happen with a non human front office assistant. Similarly, with the advancement in the brain interfaces and in the lines of the movie "Minority Report", the Police and investigation authorities may get on to crime prevention mode, i.e. they will get to know the moment you think of committing a crime and technologies like virtual presence, surrogates etc, this might be accomplished without any human casualties.

There are more such advancements and in this blog, my attempt is to present few scenarios that could be a possibility in the near future and the effects that this can have on various attributes of mankind.

Glass: With further advancement Google Glass kind of gadgets could be miniaturized and could be worn like contact lenses. These lenses would be able to interface with things around you. For instance, the refrigerator will greet you with the current temperature and you will know what is inside various containers, by looking at it (without opening) and will also indicate its details like quantity, how many days it is stored, etc. Again with added gamification, one will enjoy performing various tasks on the kitchen table. These things while assisting you on performing these tasks like chopping vegetables, it will also keep a score of how you perform, so that you enjoy doing these tasks. These gadgets coupled with access to public and private data stores help you in decision making, which can enhance one's Personal Intelligence (PI). Check out this video to have a glimpse of what I have tried to narrate here.

Brain Interface: Gadgets like Brain Link are already in the market, which coupled with related applications on smartphones gives beneficial gaming experience like attention training, meditation, neuro-social gaming, research and knowledge about brain. Most of us would have watched the movies 'Surrogates' wherein humans would stay indoors while their surrogates would go out to work and 'Minority Report' where the police and justice department would get alerts the moment some one think of committing a crime. Quite many science fiction imaginations in the past have become reality now. Recent research accomplishments evidences that even the fiction exhibited in the above movies might become a reality some day that is not very far away. For instance, researchers at Harvard have demonstrated a non invasive brain-to-brain interface wherein humans could control animals with their thoughts alone.

Given that continued advancements on the brain interface will further this accomplishments and coupled with various other inventions, the next generation of man kind may experience the following:

• Personal Intelligence can be augmented by wearing or embedding devices and / or gadgets.
• Though humans can have private thoughts, these will be subject to review or audit by government agencies and no wonder securing your thoughts would become absolutely essential.
• Shopping will be virtual and all products can be virtually felt / experienced sitting at home and then can be ordered.
• All 'things' would have interfaces to interact with human.
• Blink or double blinks can be programmed to perform certain actions like taking a snapshot of what you have been seeing at that moment, etc.
• Artificial or Virtual dreams will become reality and one can have choice of dreams and choice of character. Extending this, one would be able to watch a favorite movie as they sleep and cast themselves as a character in the movie.
• With Body Area Networking and embedded nano chips across various critical body parts, self diagnosis with alerts might be a possibility.
• Human disabilities can be worked around using robotic body parts and brain interface technology.
• The hacking community would sharpen their skills and would explore opportunities of hacking human thoughts and human memory, which could be the biggest security and privacy threat to combat for the security experts.

Here are some more videos demonstrating the innovations that are taking place around human technology interfaces:

• Ford takes SYNC to the next level through the use of configurable controls and the use of an electronic personal assistant, or "avatar," named Eva
• Someday well be living be living on and under the oceans. This idea isnt farfetched and if it comes true then heres the answer to a new type of underwater transportation system.
• Using a brain-computer interface technology pioneered by University of Minnesota biomedical engineering professor Bin He, several young people have learned to use their thoughts to steer a flying robot around a gym, making it turn, rise, dip, and even sail through a ring.
• Cathy Hutchinson has been unable to move her own arms or legs for 15 years. But using the most advanced brain-machine interface ever developed, she can steer a robotic arm towards a bottle, pick it up, and drink her morning coffee.
• At Barcelona University, scientists are working on a European Research Project to link a human brain to a robot using skin electrodes and video goggles so that the user feels they are actually in the android body wherever it is in the world.

The pressure points of Cloud Adoption

The values and benefits of cloud adoption is increasingly clear and well known. Not to be carried away with these values and benefits, it is important to identify and be aware of the pressure points that the Cloud Adoption brings in as called out by ISACA in its white paper titled as ‘Guiding Principles for Cloud Computing Adoption and Use. Essentially the differences in technology itself and its use impacts the way IT is governed and managed and the management’s reaction to these impacts brings on the pressure points as well, which need to be managed.

Differences such as change in cost allocation from capital to operational may have consequences that may not apparent at the beginning. For instance, contracting for a cloud based software would be an operational spend and may have a lower cost of entry and thus, such decisions may fall outside the review and approval process. While in most cases, the pressure points are to be managed as risks, these are not necessarily risks.

Speed and Agility

The time-to-market is a driver for cloud adoption as solutions to meet market needs would be available more quicker at lesser cost though there could be gaps in meeting the exact requirements. This agile exploitation in a reduced time frame puts greater pressure on enterprise, in which culture, process, and human factors related to technology have been developed to support longer development cycles and long term technology use. This pressure when not handled appropriately could result in increased risk level in the following areas:

• An unbalanced prioritisation of value over trust in technology solution choices
• Missed opportunities when other alternatives are not considered
• Recovery mishaps because fallback positions are not fully exploited
• Missing functionality if full requirements are not identified
• Increased long-term costs due to reliance on multiple short-lived solutions
• Reduced performance when enterprises are hesitant to introduce new solutions because of existing technology investments

Changing Boundaries

The reliance on cloud providers calls for change in the roles and responsibilities within the enterprise and transfer certain responsibilities to outside parties. Contracts and SLAs with service providers attempt to assign accountabilities, but governance dictates that the enterprises themselves, their board and management remain accountable. With this, the locus of decision making changes from governance functions to business line leaders. This change in the organizational boundaries can put greater pressure on enterprises. The risk outcomes out of this pressure point could be:

• Role confusion when accountabilities and responsibilities are not clearly defined
• Diminished effectiveness when decisions are made without engaging in a wider consideration of trust and value before cloud acquisition
• Failure to satisfy constituent and end-user expectations for protection and privacy
• Project delay and increased costs due to the need for personnel with governance responsibilities to revisit cloud plans
• Unclear specifications of provider responsibilities and accountabilities in SLAs
• Incomplete information being provided to board members and senior management

New Technologies and Technology Expectations

Cloud follows a sequence of disruptions in how technology is viewed, integrated into organizational strategy and managed and in how IT risks are identified and managed. Areas of high pressure can result when strategy and enterprise architecture do not consider the unique qualities of cloud computing and when enterprise processes and procedures do not easily adapt to changes made possible by cloud computing. The following risks could be the outcome of this pressure point:

• Missed opportunities to extract value from the integration of cloud and internal systems
• Increased vulnerability from incompatibilities and inconsistencies between cloud and internal systems
• Less than expected results when human factors are not considered in the design and integration of cloud services and infrastructures
• Levels of organizational performance that do not meet expectations because cloud solutions do not fully support organizational processes
• Levels of technical performance that do not meet expectations because processes do not take full advantage of cloud capabilities

Level Playing Field

Cloud computing removes the advantage that large enterprises have traditionally had in terms of availability of technology specialists and technical sophistication. Smaller enterprises now have the ability to leverage the cloud services and use technology sophistication that large enterprise used to enjoy. This brings the small and medium enterprises on an equal position with much larger enterprises. This level playing field can have an impact on the strategy and its implementation. Ignoring this impact can result in increase of risk levels in the following areas:

• New entrants claiming a segment of traditional market dominance
• Strategies that do not address competitor capabilities
• Less-than-expected benefits received from technology-dependent solutions

Utility Services and Service Supply Chains

With cloud computing, where computing is viewed as a utility, focus is shifting to the value and benefits obtained from such utilities. Agile enterprises benefits from solutions that can be used as needed and discarded when they no longer provide value. This view of computing as a utility and the delivery of solutions supply chain of information systems solutions puts greater pressure on enterprises that contain a culture that is not accepting of utility solutions, a structure that does not facilitate cooperative planning and processes that cannot take advantage of computing solutions provided as supply chain of utilities. Ignoring this could result in the following risk outcomes:

• Over-investment of resources in planning and building internally developed information system solutions
• Less-than-optimal results when value-producing cloud utilities are missing from the total solution
• Duplication of effort when specialist services available through cloud providers are not integrated as part of system management
• Less-than-expected results when utility components are not integrated into and managed as an information system capability supply chain

In the white paper, ISACA suggests that enterprises follow a six guiding principles that can help illuminate the path for cloud adoption. Click here to download the complete white paper which is available for registered (free registration) users.

Emerging Cloud Trends – Impact on IT

A recent Gartner Report identified five Cloud computing trends which could affect the cloud strategy through 2015. While Cloud Computing has a significant potential impact on every aspect of IT, the uncertainty, confusions and misunderstandings continue to exist and the five sub trends would be accelerating and need to be factored into the planning process. This means that the CIOs would be inclined to revise the cloud strategies to align with these trends. This will also mean that the enterprises would need IT workers with skills that could help in making this strategic shift successful. Here are the five sub trends and the skills that these trends would demand.

Formal Decision Frameworks facilitate Cloud Investment Optimization

The benefits of cloud include the shift from CAPEX to OPEX models, reduced spending, greater agility and reduced complexity. These benefits do not come just like that and they come with some challenges in the form of security, lack of transparency, performance & availability concerns, vendor lock-in, licensing constraints and integration needs etc. It is important that these benefits and concerns are carefully mapped against the needs of the enterprise and an appropriate decision is made and necessary monitoring and management processes are put in place. Each of these benefits needs to be quantified considering the organization’s current and future priorities and constraints. For instance, a financial services firm may find the greater agility as a challenge as well (as against a benefit), because, greater agility could mean more frequent changes, which would have an impact on the reliability and stability of the applications. Realizing such impact in mid-course could result in rolling-back from cloud adoption and the resulting impact is obvious.

Over the next few years, organizations would be putting in appropriate decision frameworks, more specifically for the cloud adoption so that the benefits and risks are known upfront and decisions are taken appropriately. The skills that this trend may demand include Risk Management, IT Security, IT Governance, Estimation and Metrics.

Hybrid Cloud Computing as an Imperative

As there are enough reasons for enterprises not moving all their IT on to public cloud, Gartner sees a unified cloud model, where a cloud of clouds is a possibility, in which a single cloud may comprise of multiple cloud platforms part of which could be it internal. As everyone know, the key challenge with hybrid cloud computing is the integration of application and data between on-premise and cloud applications.

This calls for existing internal applications being enhanced to support integration with external cloud applications and at the same time the cloud applications should expose APIs for consumption by other cloud applications and / or the organization’s internal applications. Applications on public cloud need to adhere to industry standards and best practices, so as to support varying integration needs of its customers. The skills that an IT professional would start seriously looking at to get on with this trend are EAI (Enterprise Application Integration), SOA (Service Oriented Architecture), ETL (Extract Transform and Load) and EII (Enterprise Information Integration).

Cloud Brokerage will facilitate Cloud Consumption

As cloud adoption proliferates, so does the need for consumption of assistance. Gartner believes that Cloud Service Brokers (CSB) are one of the most necessary and attainable opportunities for service providers, service distributors and internal IT organizations. The CSB model provides an architectural, business and IT operations model for enabling, delivering and managing different cloud services within a federated and consistent provisioning, billing, security administration and support framework. This will help the unification of the cloud services delivery and management. Gartner has designated Jamcracker as a “Cool Vendor in Cloud Service Brokerages”.

This trend will call for the IT professionals to have a great deal of knowledge on SOA in addition to various standards, practices and tools on service provisioning, delivery monitoring, billing and management.

Cloud-Centric Design becomes a necessity

Migrating existing workloads with highly variable resource needs to cloud platforms is among the immediate opportunities that many organizations are looking at utilizing. But this will not make the cloud adoption complete, as it will result in using various work-around approaches to make it work with existing applications, by-passing standards and best practices. This might work in the near term and but may not scale and yield the real benefits in the longer term. Organizations should start looking at development of cloud-optimized applications that exploit the potential of the cloud. Even internal applications should be designed with cloud-centric model, so that it can exploit the private cloud platform and would make the integration with public cloud applications easier over hybrid cloud computing platforms.

This trend will expect the application and solution architects to start acquiring necessary cloud skills, so that the solution that they architect is cloud-centric and will have identifiable service end points for use with various other internal and external applications and also factor in the support for Cloud Service Brokerages. The design patterns, standards and practices around cloud-centric design is evolving and it is important for the IT workers to keep a watch in this area.

Cloud Computing influences future Data Center and Operational Models

In public cloud computing, the providers have implemented such a model so that the ability of provisioning, delivering and managing the services is optimized and automated to a great deal. This also ensures optimal utilization of the underlying hardware and also minimizing the energy and other operational costs. Enterprises are attempting to implement the similar models within their data centers and have private clouds setup for the consumption of their own internal consumers. This trend is increasing and Gartner predicts that in the next few years any data center (small or big, internal or external) implementation would follow the cloud model.

This trend will expect the Infrastructure Architects to be cloud aware and be familiar with the underlying tools and technologies, which form part of the cloud service provisioning, delivery and management.

The skills that transform an IT Manager to an IT Architect

One of a typical question that an aspiring architect has to answer in the hiring interview is “how in your opinion an architect is different from an IT Manager?” Even I have been in the asking side, on many occasions and have not been getting convincing answers from many. This is very typical as in most organizations, even if one is titled as Architect, he or she end up managing IT as against Architecting IT. Let us attempt to compare and contrast the skills that these roles demand. Please note this is not an attempt to make out a complete list of skills of these roles.

1.       The Engagement

The Architect’s engagement starts with identification of a business pain point. At times, it would be the Architect who should spot the pain points and propose remedies. On the other hand the IT Manager is engaged the moment a project has been scoped and is ready for execution and implementation.  The engagement of an Architect starts with the challenge of making a business case (of course with the help of fellow architects specializing on specific areas) to the stake holders with appropriate quantified projections that lead to a positive RoI. When this task is done well, the projects that get shelved mid course would come down considerably.

2.       Big Picture thinking

The Architect has to be the one who can visualize the big picture of any given problem or a possible solution in line with the enterprise’s long and short term goals, the anticipated business growth and the technology trends in the related area. This visualization would help the Architects to appropriately prioritize the various initiatives and to draw out the short term and long term road maps. The big picture visualization is an integral part of the IT strategy lifecycle of the enterprise to determine the future state and plan for the transformations from current state to future state. On the other hand, the IT Manager is engaged only in the transformation tasks and there by leading the organization to the future state.

Some of the aspiring architects, when asked how would they do the capacity planning, their response was based on a pinned down Statement of Work, which in case of architect engagement would not exist and they could not think of a situation where they would be designing a solution with absolutely no requirements on hand.

3.       Project Execution

The IT managers will have teams to execute, implement and manage various projects, whereas, the Architect would be playing an independent and in most cases individual contributors. The Architects have to be with the project execution teams and help the teams by bringing in course corrections whenever they deviate from the intended plan. This role requires the Architect to possess hands on ability in the related technology, so as to hand hold the project teams during execution. The IT Managers on the other hand may not be required to do this and instead he would simply co-ordinate the engagement of Architects with the teams.

4.       Risk Management

While Risk management is essential in IT management life cycle, performing it early on adds huge value to the solution execution as it helps better decision making in terms of resource planning, training needs and of course will bring in the ability to remedy the risk. That is the challenge an Architect has to face in identifying all potential risks that the solution may lead to. IT managers also face challenges in risk management, but it will be a lot easier as many things would have gained concrete shape with less ambiguity.

5.       Staying on top of the trends

The IT Managers are not normally pressed to stay on top of the technology trends and it would be enough for them to stay on top of the technology that is mature enough and has good industry adoption. The Architect on the other hand has to stay on top of the trends and that would help him in measuring the longevity of the proposed initiative or solution. It also important for the Architect to have a good grasp of industry predictions and analysis and should have the ability to choose the less risky path to lead the enterprise to the future state.

Solution Architect - Understanding the role

I keep getting questions from some of my friends, as to what the role Solution Architecture is all about and will they be a fit for that role. For the benefit of every one out there, I thought of putting together my thoughts on the role of Solution Architect. Let us first examine what is expected out of this role and then look at the skills needed to be in this role.

As the title indicates very well, the role is expected to bring in solution to varying business problems, most which could be a product or project by itself. But, as you know, it is always a challenge to come up with a best solution due to it being intangible and that there are many quality attributes which are not completely identified and specified. There would be lots of missing links in the areas of business domain, choice of technology, hardware components, business processes, future domain and technology trends, etc  which the Solution Architect should be able to connect and come up with best solution that could last longer, so that the organization reaps the return on investing in the solution.

Some of the key characteristics of a best Software Solution are:

Longivity: While the solution must solve the current business problem, it should also be reliable, usable, secure and also future proof. This means that the solution Architect should consider the industry and technology trends that could have an impact on the problem / solution in the near and longer term.

Trade off: The challenge with the various mostly unspecified quality attributes is that they are interdependent. And meeting one such attributes may most likely mean compromising on another. Obviously, a lot of trade off has to happen between various quality attributes and such trade off should be justifiable in the context of perceived benefits for the organization. For instance, performance may have to be compromised to achieve better security. The tradeoffs have to be carefully made after considering various factors, like the risk appetite of the organization, target users of the solution, the technology platform, current IT investments of the organization, etc.

Implementation view: It is important that the solution should be devised with the intended deployment view into consideration. Without that, it could so happen that the solution as designed and built may call for massive changes to the infrastructure investments, which could be a total surprise for stakeholders. Such surprises emerging towards the close line of the project could increase the cost by manifolds or delay the project further.

The above is not the exhaustive list. There are many other factors that will have to be given due consideration before coming up with the best solution. Above all, the solution architect should be able to see that the solution is successfully implemented and put into use. That means, a lot of work in terms of convincing the stakeholders as to why this solution and not an alternative, hand-holding the design and development team and also to some extent the end users to have it implemented the same way it was intended.

With all the above, let us now try to identify the essential skills of an aspiring Solution Architect:

Domain skills: A thorough understanding of the business domain is required to first understand the problem better and second to know the potential future needs that may emerge along the same lines of the problem space. It is also important that the person has the ability to learn things fast, as in most cases, there won’t be lead time for him to gain appropriate business skills. That means, the Solution Architect should also be a Business Analyst.

Technical skills: A thorough understanding on the technology currently in use in the organization, the technology currently in use in similar industry domain and the emerging future technology trends. This knowledge is essential to ensure that the solution does not become obsolete soon and that the organization is in a position to be ahead of completion in terms of IT enabled capabilities. At the same time, applying a new technology early in its evolution has its own issues and it is always better to wait for the technology to evolve and mature as more and more organizations adopt the same. It is important for a Solution Architect to closely follow technology trends and gather enough knowledge to understand what could be the best fit for solving various business problems on hand. He should have enough understanding of the technology chosen, so that his team (mostly himself) comes up with a prototype to establish that the solution really solves the problem. However, as the solution goes further down the implementation lane, the Solution Architect should be able to demonstrate hands on skills, so that he could command expertise and be the go to person for resolution of issues.

Team skills: Though mostly the Solution Architect will be an individual performer, some organizations may have dedicated teams to assist the Architects. Even in case of Architects acting as individual performers, the solution is implemented by a project team. So, the Solution Architect needs to be a team player and should with his domain and technical expertise, lead the team by example.

Process / Project Management Skills: Needless to say that the Solution Architects have to have the Project Management skills too, as one may have to manage the pre-solution activities as a project. For the purpose, he has to be familiar with the processes as well.

That means, the Solution Architect should be an all rounder with moderate to expert level skills in all the areas.  On top of these skills, one has to understand that solutioning is not just a science, but also an art, which is mastered with years of experience over as many projects and years involving various technologies and domains.

There could be different views on this and comments or opinions are welcome. 

BYOD – Yet another challenge for IT heads

For those, who are not familiar with the term BYOD, it stands for “Bring Your Own Device” and use it to achieve your work goals, be it within the company or anywhere else. A simple example for this is when an employee uses his own iPad to access his corporate emails, or use any other wi-fi enabled device to connect to corporate wi-fi network and use it to perform certain work related tasks. This has been in practice with the education and training companies, where the students / participants are expected to use their own devices, subject to meeting of the required minimal hardware and software specifications. Thanks to the last recession the recent explosion of the smart personal gadgets, companies are increasingly considering allowing this. 

The factors that drive the BYOD amongst corporate are:

1.  Increased Productivity - Employees are expected to be happy working on their favourite stuff and in turn that is likely to bring in increased productivity.
2. Better Mobility – Organizations with mobile workforce, who typically work on the move, feel that BYOD could offer better mobility and flexibility.
3. Cost Savings – Though this may not be a real benefit, as organizations may end up spending considerably on mitigating the risks that BYOD brings on board, this is considered as a factor driving the increased adoption.
4. Influence from senior executives – Typically if a senior executive buys a latest gadget and then using it in the workplace to do their work.
5. Decreasing client installs – With increased adoption of Cloud based applications, all that a user need to access the enterprise application is a compatible web browser and this favours BYOD.

Certainly BYOD brings on board a lot of challenges to the IT department and here are some of the key challenges:

1. Support – The IT department have to start supporting varying make and models of smart gadgets running different operating systems and web browsers. Unless the IT department comes up with the list of gadgets that they can support, it could soon be a nightmare.
2. Licensing – If there are certain third party components to be installed on the smart devices, then it is better to have the licensing terms of the component vendor verified, as some vendors may impose restrictions in installing such components on devices other than those owned by the organization.
3. Network and Application Security – When employees use the organization provided devices, they are appropriately hardened in line with the security policies of the organization. But in case of BYOD, the employees for sure would not like to have their devices hardened for work use, instead they would like to be the administrators of their own device and play with it in whatever way they want. On the other hand, employees may even go ahead and install more and more mobile apps of their choice, some of which could even be malware.
4. Data Security – Whatever data that is cached or stored on the gadgets, as the devices are used for work are subject to be easily compromised.

For sure, this is yet another challenge that the IT managers should be ready to face soon, if not now.  

Future of Personal Computer

With the evolution of smart phones and tablets, the survival of Personal Computer could be under threat. Let us examine, if there is a possible thing that PC alone can do.

Thick Client Applications: We have started seeing the increasing number of applications moving to the cloud and one just need a browser and may be an appropriate pug-in to run a cloud application. Even heavy weight applications like ERP suites and Business Intelligence Suites are now being offered over the cloud. In few years from now, I don't think there will be any compelling need to use a thick client application.

User Convenience:  Yes, a bigger monitor and a regular keyboard with a mouse will really be convenient to work on a PC. But do we need a PC just to have a bigger display and the key board? Not really, some of today's smart phones are dockable on to a device, which facilitates connecting to a bigger display and keyboard.

Higher Computing Power: When the applications are served out of Cloud, much of the processing happens elsewhere on some server(s) located over the cloud, and not much power is required on the client device. That is not the end, in few years from now, the smart phones / tablets will equally sport a high end processor with even multiple cores.

Extreme Gaming: Most of the popular games today are online games. Gamers also prefer online games which connects buddies from all over the globe to join and play together. More so, because the gaming service providers gain more in the form of Ad revenues in case of online games than Thick client games. Above all, there are special purpose gaming consoles in the market for extreme gaming.

Enterprise Computing: While it could be ideal to go with enterprise owned secured and locked down personal computers to access and process enterprise information, but that does not mean that they have to be PCs. Even now most enterprises are encouraging their employees to work from home on a Laptop, there by saving so much of energy costs at the physical location and at the same time commuting time for the employee. The evolving tablets could easily replace the Laptops.

Research firm Gartner slashed its growth forecast for the global PC market this year to 3.8 percent from 9.3 percent citing boom in media tablets.

You name one thing, we can think of how tomorrow's personal gadgets could address that. Would like to here from you on this trend.
