Virtualize and Consolidate – Many companies are still thinking that, for
every server you need one dedicated hardware platform. However, very large
and successful IT organizations have fully adopted virtualized infrastructures. While there still remain some applications that cannot run in a virtual environment, those applications are becoming fewer and farther between. By virtualizing servers and their applications, you can leverage unused CPU cycles, idle memory, and shared drive space.
