| A few years ago, the idea of running multiple operating systems concurrently on the same computer captured the imagination of the computing industry. Virtualization became the hot buzzword and projects were launched to fulfill the dream.
With virtualization, you don’t need an extra computer every time you want to bring up a new server. Extra demand on your infrastructure can be handled by simply launching new guest operating systems. An entire guest can be dedicated to a single application, and that guest can be different than the host operating system. Using features like storage virtualization, guests can be moved around on-the-fly to make the best use of your computing hardware.
Now you have been asked to pick the right virtualization solution for your business. Ahead of you is the daunting task of sorting through competing technologies, finding what best suits your situation, and getting it all to work within your IT infrastructure. What you need is a guide to virtualization choices that clearly describes how to implement those choices. Practical Virtualization Solutions is that guide.
All sorts of questions might be in your mind right now. What new computer hardware demands must I meet? Should I use Windows or Linux as my host operating system? How do I secure and maintain my guest operating systems? Should I use local or networked storage? What are the differences between server and desktop virtualization?
Besides helping you answer those questions, Practical Virtualization Solutions also answers some questions you probably haven’t even thought of yet. Where can I find prepackaged server appliances to quickly configure specialized Web, file, or CMS servers? How can I migrate an existing physical system to a virtual system? |
