Cloud Computing Helps Virtualization “Return to the Spotlight.”

“At first glance, cloud computing can appear to be “virtualization taken to its logical conclusion.” After all, if the main benefit of virtualization is to consolidate data center resources and increase the speed of provisioning, then cloud is the ultimate pay-off: don’t own the resources at all and cut provisioning down to a few minutes with instant self-service gratification.

But upon further thought, cloud seems to be giving virtualization a return to the spotlight. A recent Gartner study noted that cloud computing is the number two priority for CIOs – trumped only by virtualization. And many panel discussions and sessions at recent cloud-related trade shows have addressed the benefits of extending virtualization footprints within the data center and starting to turn these into internal clouds, or at least “cloud-like” environments.

Still More Virtualization To Be Done

So is virtualization “what’s old, but new again?” Remember that most enterprises have adopted virtualization in some way, but those that have are only about 20 percent virtualized so far. And many companies have large investments in existing hardware and virtualization licenses that they’d like to use more efficiently.

So there’s plenty of room left to penetrate, and there’s still lots of opportunity for optimization and better management. Virtualization has primarily been used for consolidation, not for optimizing workload management and self-service. And many companies have large investments in existing hardware and virtualization licenses that they’d like to use more efficiently. In many ways, cloud computing has emerged on the scene as a disruptive force while virtualization is still an evolution in progress.”
