The recent adoption of virtualization technologies lowers the amount of hardware required and reduces power consumption to some extent. But it also raises management complexity since there is no longer a permanent and exclusive relationship between physical resources and the software that runs on it. If one then chooses to implement a Service Oriented Architecture (SOA) on top of that, the increase in complexity multiplies. Bridging the gap between service demands and IT capabilities requires a higher level of performance management for IT resources. Moving to mature Capacity Management tools and processes lowers costs, improves service quality and increases IT productivity since staff can focus on the most important duties rather than fighting fires.
