March 03, 2009, 5:30 PM — "What we like best about virtualization is the dynamic nature of it," say Nelson Ruest and Danielle Ruest, authors of Virtualization: A Beginner's Guide. "The server is no longer constrained in its physical envelope and because of this it becomes much more malleable which makes it so much easier to work with." Their advice to newbies: Start with the free versions of virtualization technologies available from Sun, Citrix, VMware, Microsoft, and many others and test, test, and retest.
This is part of a regular series that highlights new books and their authors. Also in this series: J. Peter Bruzzese on Exchange Server 2007, Raffael Marty on security visualization, Joel Scambray on exposing the hacker's advantage, and Scott Hogg on IPv6 security. (You can find all the installments in this series here.)
What do you like best about virtualization? The dynamic nature of it. The server is no longer constrained in its physical envelope and because of this it becomes much more malleable which makes it so much easier to work with. When machines are nothing but a set of files in a folder, they can easily be copied from one location to the other, they can easily be duplicated and they are much easier to back up. What's even better is that it is fun to work with virtualization technologies.
Words of advice for those just getting started with virtualization: The best thing to do for newbies is to start with the free versions of virtualization technologies. Free virtual engines are available from Sun, Citrix, VMware, Microsoft, and many others. They will help you get your feet wet without having to invest a lot of money.
