This is the introduction to a five part series focusing on identifying the problem and sharing proven strategies for transforming legacy datacenters and infrastructure to next generation datacenters that operate in a cloud computing like model for enterprise IT.
The article builds on concepts I introduced in the book I published in June of 2009, “Next Generation Datacenters in Financial Services (Driving Extreme Efficiency and Effective Cost Savings.” (Elsevier). It is a continuum of thoughts I have shared in the past along with influences of recent dialogues with technology executives and the problems they continue to face.
One of the fundamental barriers to business today is the intersection of the “day in the life” of the business and how that executes across the IT supply chain. The barriers caused by this Business-IT Chasm, include limits placed on customer interaction, ineffective & inconsistent decision-making, time to react to market changes and the cost to do business.
This typically results across more organizations because of disconnected decisions and actions made by both business and IT.
The business can be faulted for not providing the insight into how their business operates in a day in the life on an end-to-end process and execution basis. Instead each business function drives their application and IT folks to build systems focused only on their area of responsibility creating a in complete view of business execution necessary for optimal system development.
The IT organizations take this siloed input from the business and expand on the concept in terms of applications, data repositories and infrastructure systems. Both a top down and bottom up conflict occurs. Application and data folks build their own vertical oriented capabilities. The infrastructure folks define and provision infrastructure based on their datacenter strategy of compute, network, storage, placement, power, cooling and physical characteristics. This amplifies the silo disconnect resulting in waste, quality of delivery barriers, cost limitations and creates operational risk.
Take this scenario described above and multiply it across the various business functions, business processes, business channels, products and services and you get an input factor of many. Take this input factor and implement it into the Business to IT factory conversion process and the output result is business limiting system caused by a ineffective and poorly aligned system creation process.
Additional factors facing organizations include a problem of legacy technology that has limitations ranging from manageability, integration, efficiency, costs, etc… On top of this, most organizations have not implemented the discipline to document and maintain accurate understanding of their systems and how they execute on a daily basis. Then you have the “pain avoidance” strategy where firms have pushed off upgrades and enhancements – resulting in unsupported systems that creates even greater risk and limits the change strategies firm may wish to implement.
There is not silver bullet or single strategy that solves all. There is however, proven methods and successful strategies that multiple firms have employed to attack the legacy problems in their existing datacenter infrastructures and iterate their way towards next generation datacenters and IT delivery ala Cloud Computing Models.
In parts 2 thru 5 of this series, a four step strategy for attacking legacy IT will be described. These steps can be summarized as:
- Insight – day in the life understanding of both business and IT in terms of execution, historical decisions and actions and objective understanding of the actual situation as it exists today.
- Alignment – creating a common language, taxonomy and system creation model to produce repeatable results.
- Control – specific actions, tooling, process and approach to ensure the appropriate change occurs and re-occurs successfully.
- Sustainment – mechanisms and processes instituted in a repeatable discipline to ensure consistent results and avoid falling back into the legacy traps.

The major cloud platforms defy a simple, side-by-side analysis. Each of the major IaaS public-cloud platforms offers their own unique strengths and functionality. Options for on-site private cloud are diverse as well, and must be designed and deployed while taking existing legacy architecture and infrastructure into account. Then the reality is that most enterprises are embarking on a hybrid cloud strategy and programs. In this Power Panel at 15th Cloud Expo (http://www.CloudComputingExpo.com...

The move in recent years to cloud computing services and architectures has added significant pace to the application development and deployment environment. When enterprise IT can spin up large computing instances in just minutes, developers can also design and deploy in small time frames that were unimaginable a few years ago. The consequent move toward lean, agile, and fast development leads to the need for the development and operations sides to work very closely together. Thus, DevOps become...

The Internet of Things is a misnomer. That implies that everything is on the Internet, and that simply should not be - especially for things that are blurring the line between medical devices that stimulate like a pacemaker and quantified self-sensors like a pedometer or pulse tracker. The mesh of things that we manage must be segmented into zones of trust for sensing data, transmitting data, receiving command and control administrative changes, and peer-to-peer mesh messaging. In his session a...
