In my previous blog, I talked about the impact of the world going digital and the changes in the enterprise value chain amid today’s digital context. I stressed on how datacenters should sense, analyze and control their operating environment in today’s digital world and by rightly doing so, how they can bring about fundamental transformation amongst themselves.
Having spent many years in and around datacenters, there are many secrets and unpleasant facts that are never discussed broadly. Most datacenters have technology layers beneath it that are getting tested on hidden vulnerabilities, non-standard configurations, resiliency gaps, unsupported hardware, etc. Veterans in some of the acclaimed datacenters have confessed war stories and the truth of ticking time bombs that are not apparent. All of these doesn’t necessarily mean a dooms day scenario. Seasoned administrators, who takes these challenges head on know how to manage these and continue delivering uninterrupted services.
However, things can take a different note when a steady state of a datacenter is disturbed. One is challenged when it comes to transformation and the changes required to retrofit are far too disruptive to present deployments that even the strong-willed can shy away. Therefore it is a common topic of discussion on how can we retrofit and transform a working data center without creating business disruptions. I have always argued that a data center transformation is nothing short of brain surgery. It has a potential to cause irreversible impact to business. It is not to scaremonger but there are many stories when seemingly tried and tested procedure go wrong and create serious damages to organization reputations.
While all the above appear fine, shying away from establishing the much needed capabilities is not an option. With so much at stake for the businesses, how can we accomplish these changes and transform is the critical question.
In this blog, I wanted to share some insight based on the learning from many workshops, client engagements, advisor interactions, RFPs. At a high level, the transformation options can be summarized into two main approaches. The two possible approaches are:-
a) A big bang transformation that will establish a new footprint with all the desired capabilities and progressively move workload there and eventually retire all old setup.
b) An incremental approach in which new capabilities are introduced into the existing footprint over a period of time with short term and long term goals till all the required capabilities are achieved.
The comparison of the two approaches looks like this:
Transformation Approach
Big Bang Transformation
Incremental Approach
The pros and cons of the two approaches is captured below:

If we have to go by some recent trends, the approach is leaning towards a big bang approach. The external impact to business and the push from the stakeholders stands out as the key reason why the big bang approach is finding favor. I wanted to share a few insights from some of the recent engagements that we are executing and how the big bang approach was pursued.
It is an interesting time in the evolution of IT. There is need for pushing the envelope on various fronts for internal IT organizations and its partner ecosystem together to be able to accelerate key capabilities for business in the digital world.
