Getting Virtualization Right-
The idea of multitenancy that is all the rage in the SAAS (software as a service) world has some relevance for chargeback. IT managers should look into usage measurement tools so that they can provide business users with fairly accurate figures of what it costs to get into the virtualized infrastructure. As energy and cooling costs escalate and rack space becomes scarcer, chargeback billing will become a core component of managing a virtual server infrastructure.
In my story about managing virtualization, I recommend some ways that IT managers can tame existing server sprawl. This sprawl can be avoided altogether at companies just beginning or planning a server virtualization if the following steps are taken.
