Infrastructure Optimization, Typically, the IT services buyer forecasts usage utilizing a number of factors at his/her disposal:
- Prior contracted capacity—that is, what was signed up for in the past.
- Forecasted business objectives, along with the inherited success criteria for objective completion, that will dictate IT demand—what will IT infrastructure needs look like over the upcoming quarters relative to in-budget and market-responsive projects.
- Risk tolerance by business line that dictate Service Levels which are acceptable in fulfillment of those aforementioned objectives.
A challenge exists in obtaining the right amount of IT capacity so there is minimum under-utilization (resulting in waste) and at the same time insuring that service levels can be achieved, especially given different business and service objectives.
It is important to consider and recognize the following differences in IT infrastructure demand versus supply as we see how a solution to efficiency and waste measurement of compute capacity based on the right set of metrics immediately adds value to the buyer of compute services/capacity:
- Contracted Capacity = Theoretical Maximum—What is the contracted maximum compute services the buyer has under commitment and SLA the supplier has agreed to provide.
