Before starting on a utility computing project, it is important to have business metrics for the existing environment in order to tell whether the new services offered by the ITO are actually better. The sections that follow give some examples. 1 Hard metrics r Deferred capital costs for storage and server infrastructure. By r r improving utilization and exploiting virtualization technology, existing resources can be used in preference to purchasing new ones. Reduced cost per TB or per server due to increased discipline of storage/server classiﬁcation.
2 Soft metrics r Accelerated service time for new capacity requests. This can be r r r measured through the request (or ticketing) system as the time from when the request is created to when it is satisﬁed. On a broader level, it can be measured as a more rapid time to market for the product that the business unit who is consuming the IT is delivering. Increased uptime due to better conﬁguration decisions and dynamic conﬁguration capabilities. Known good solutions based on templates ensure that problematic conﬁgurations are a thing of the past.
The concept is simple, by reorganizing IT and applying some new principles, IT utilization will increase, efﬁciency will improve and costs will go down. 2 The blind men and the elephant. 10 WHAT IS UTILITY COMPUTING? 3 IT seen from different perspectives. everyone is looking at it from a different perspective everyone concludes it to be something different. Recognizing that utility computing means different things to different people, and understanding that each has a different set of requirements that need to be satisﬁed from the outset actually makes it easier than trying to put them all together.
