While virtualization is part of any cloud offering, these applications in and of themselves do not comprise a complete private cloud deployment, stated consultant David Linthicum in a recent article for Info World.

"Virtualization is typically a part of most private cloud computing architectures and technology solutions, but it's not the solution unto itself," wrote Linthicum. "I hate to see somebody try to pass off a cluster of virtualized servers as a true private cloud, lacking auto- and self-provisioning or other features that make the use of private clouds valuable."

Instead, companies should look at virtualization as just one part of the private cloud puzzle, stated Linthicum in the report. Among these other considerations are security, valued added, infrastructure requirements and legacy system integration.

Once these complementary pieces fall into place, companies may find that their private clouds offer many of the benefits of their public counterparts, along with additional security measures to put data protection fears to rest.

According to a new survey by CompTIA, regardless of the cloud model being deployed, a growing number of small- and medium-sized business expect to spend more on the platform in the near future, as well as devote a greater amount of their IT budgets to the new computing mode.
