Myth 1: My legacy business-critical applications are married to the underlying hardware; changing the platform is a major undertaking.

Truth: Virtualizing an application is very different from re-platforming and is a much simpler undertaking, since a virtual machine encapsulates the entire OS and application. While infrastructure best practices must be followed, there's typically no modification at the application level.
Even though virtualization has represented a wave of change throughout enterprise IT for almost a decade, there remains skepticism about such a fundamental change in the way a corporate IT system operates. Most of this skepticism, certainly, can be found in older enterprises whose on-site IT works just fine, thank you. Nothing wrong with that, so why change something that isn't broken? The problem is looking ahead can be challenging, because it takes extra thought, work and expense to do it correctly. Virtualization requires planning. All hardware—mechanical or solid state—isn't going to last forever. Eventually, it will break down and die; software eventually is going to become outdated, corrupted or non-supported. Moving physical servers and their software into a virtualized environment takes away these age limits and enables more options for their owners. VMware, located in Palo Alto, Calif., is the world's largest provider of virtualization technology. A recent IDC market report indicated that more than 85 percent of the world's IT systems are running at least one of VMware's hypervisors. Following is a list of myths that Shruti Bhat, Product Marketing Manager for VMware, and her colleagues often hear about—and VMware's response to each.
