In my last post, I asked about your color in Cloud Computing. If you are interested to read my posts, surely you know what it is? Or maybe not so well !
According to Wikipedia, “Cloud computing is Internet (“cloud”) based development and use of computer technology (“computing”)”. In simple terms it means running hosted services over the internet. Yet cloud services differ from traditional hosted services on several factors. Cloud computing allows a company to pay for only as much capacity as it needs and the user requires no more infrastructure than a computer and an internet connection. This technology has made possible much more efficient computing by centralizing storage, memory and processing.
Significant improvement in server virtualization, distributed computing and high-speed internet have contributed to the birth of cloud computing capacity. All this points to a rosy future in business computing, as Cloud based services can cater to all the IT demands of any organization. But roses apart, there are some thorns also.
Have you heard about ITIL? It stands for IT Infrastructure Library, ITIL was design before Cloud computing influence. Its present avatar being V3. It provides a detailed framework of guidance for IT Service Management and has been widely accepted worldwide as a standard. Their website address is http://www.itil-officialsite.com, look also at http://www.itsmfi.org for ITIL promotion. IT Service Management has five core books comprising the entire Service Lifecycle, namely, Service Strategy, Service Design, Service Transition and Continual Service Improvement.
I managed different programs for IT Service Management transformation. You can be sure that ITIL is a good framework. But migrating to Cloud computing will have a huge impact on the first two modules of the Service Lifecycle.
Key processes and activities in Service Design, such as, Capacity Management, Availability Management, Information Security Management and Supplier Management will be affected to the point of either being redundant or greatly weakened.
Does this means that Cloud computing and ITIL are as incompatible as chalk and cheese?
Both have emerged in the IT scenario as great assets and have indisputable plus points in their favor.
One possible solution is to use Cloud computing while keeping ITIL as the reference for IT Service Management concepts. One area, where ITIL will be useful, is making Cloud computing more accurate on Infrastructures Information Systems : keep using ITIL for your Infrastructure Information System as a reference. Structure your information model with all informations requiered for ITIL processes. After, integrate your processes with Cloud needs and usage.
A hand over is also necessary between the design teams (Service Design, Life cycle : Service Managers, Service portfolio managers) and the implementation teams (Service Transition : Architects and Solution managers).
I am convinced that success story about Cloud implementation are linked to the capacity of the organizations to manage transversal links between these two teams.
If this evokes more interest for you, books on ITIL can be found at the following: www.itil.org.uk and www.itilbooks.com. You can also read Thierry Chamfrault’s book (sorry in french, maybe an english version soon), he is my Master for IT Service Management / ITIL and Information System Design.
So now, are you going to marry ITIL usage with your Cloud implementation ?
