Application myth: The applications we use can’t be virtualized.

In the recent past, when computers and servers had a single CPU, making some applications’ work virtually (like Microsoft SQL or Exchange) was almost impossible. Today, with CPUs built with two, four or more cores; these and other applications are very successfully running virtually.

Virtualization platforms today offer larger hosts at the same cost as yesterday’s systems, which means far more available capacity for virtual workloads. The key to virtualizing more demanding workloads today is simply proper planning and a solid understanding of the technology. If your applications run today on a physical server, they’ll run on a virtual server. Red Hat is one company that guarantees successful physical to virtual migration for applications. Applications rarely connect directly to hardware resources in such a way that would make them unusable on a virtual machine.

The exception that gives this myth some reality is database-heavy applications. Those applications need to be on a virtual system with others that require less intense input/output requirements.

Virtualization, one of the fastest growing trends in IT, lets any organization run multiple server functions on a single computer. Virtualization also makes it easier to start up new server emulations quickly. In case of failure, organizations can move server functions to new computers without interrupting service. Beyond saving a lot of money on large sites, virtualization is also moving to PC networks and serves as a foundation for cloud computing. Many myths surround virtualization. Some started when past limitations still existed. Other myths get started and spread by those who have separate agendas or those who have a limited understanding of virtualization. Here are some of the most common myths, identified by Global Knowledge.
