Virtualization For Dummies

Virtualization has become a "megatrend"--and for
good reason. Implementing virtualization allows for more efficient
utilization of network server capacity, simpler storage
administration, reduced energy costs, and better use of corporate
capital. In other words: virtualization helps you save money,
energy, and space. Not bad, huh?

If you're thinking about "going virtual" but
have the feeling everyone else in the world understands exactly
what that means while you're still virtually in the dark,
take heart. Virtualization for Dummies gives you a thorough
introduction to this hot topic and helps you evaluate if making the
switch to a virtual environment is right for you.

This fun and friendly guide starts with a detailed overview of
exactly what virtualization is and exactly how it
works, and then takes you on a tour of the benefits of a
virtualized environment, such as added space in overcrowded data
centers, lower operations costs through more efficient
infrastructure administration, and reduced energy costs through
server consolidation.

Next, you'll get step-by-step guidance on how to:

• Perform a server virtualization cost versus benefit
  analysis

• Weigh server virtualization options

• Choose hardware for your server virtualization project

• Create a virtualized software environment

• Migrate to--and manage--your new virtualized
  environment

Whether you're an IT manager looking to sell the idea to
your boss, or just want to learn more about how to create, migrate
to, and successfully manage a virtualized environment,
Virtualization for Dummies is your go-to guide for virtually
everything you need to know.
