Now that you know what virtualization is all about, it is time to find out if virtualization is indeed what you need. Jonathan Hassell, of LinuxInsider, writes a short guide to determine if virtualization will work for you and your enterprise. Run through the steps and determine if the solution works for you.
Personally, having limited hardware to serve 600-users, virtualization surely makes it easier for us to manage the different services. One container (in Solaris) running a mail server, another running as web server and another as Database server make it convenient for us to simulate a multi-tiered system for academic purposes. :)
