Accurately predicting capacity requirements for information technology resources in physical, virtual and hybrid cloud environments

摘要

A method, system and computer program product for accurately predicting capacity requirements for Information Technology (IT) resources in physical, virtual, cloud and hybrid cloud environments. The business demand is translated into IT application demand, which is translated into IT architecture layer demand. Resource groups are created for each IT application, IT architecture layer and resource type combination. The utilization for each IT resource group within the IT architecture layers is computed using the created resource groups, IT application demand and IT architecture layer demand. Under or over-utilized IT resource groups may be identified using the computed utilization for each IT resource group. Upon identifying such IT resources, an optimal resource profile (e.g., number of servers) for each resource group is computed. In this manner, the utilization of IT resources can be more accurately predicted thereby allowing the IT resources to be used more effectively without over-utilizing or underutilizing these resources.
