Virtualization is one of the hottest trends in IT, and for good reason. Virtualization can help save your organization plenty of money, as well as reduce your overall ongoing staffing, support and maintenance needs.
Still, virtualization isn't a universal remedy. There are several things virtualization can't do for your organization, and understanding the limitations of virtualization is as important as understanding the benefits.
Here are some of the biggest virtualization myths:
1. Virtual machines have higher availablility and reliability. This is one of the "features" of virtualization that vendors often talk about. They point out how applications can easily be restarted during an outage, for example. Unfortunately, virtualization also creates a single point of failure in the one physical machine. Complement your virtualization with orchestration management, however, and you can actually wind up increasing both availability and reliability.
