Is virtualization cloud computing?

Virtualization as an element of cloud computing
Cloud computing is as much a methodology as it is a technology. You cannot plan any single element without considering the effect on the others. You also have to add in practices and policies that govern chargeback, monitoring, procurement and many other facets of your IT infrastructure.

For example, the ability to rapidly provision virtual machines does no good if it still takes six weeks to order and install a host server. Furthermore, procurement will always be a problem if chargeback is not recovering costs, and that requires resource and utilization monitoring. If your storage and compute resources have different provisioning schedules, they'll have to be documented and reconciled to properly forecast demand. I could go on, but your business requirements ultimately drive everything.

Private cloud computing does not center on virtualization or any one technology. It uses a set of technologies that have been aligned to be highly flexible and provide a wide range of services. This approach does not require virtualization, but virtualization does lend well to the core concepts of cloud computing.

Virtualization and cloud computing are also so closely connected because the major hypervisor vendors -- VMware, Microsoft and Citrix Systems -- are putting a lot of emphasis on the cloud. They have closely aligned their products with tools and complementary technologies that promote the adoption of private cloud computing.

Cloud computing is a rapidly evolving discipline, and one that will reshape org charts as fast as it will change data center layouts. It closely aligns with virtualization, but it takes many technologies to be successful.
