ComputerWorld Australia published an interesting article on virtualization: A Virtual Breeze. This article would be useful for IT managers or system administrators who are only thinking about implementation of virtual servers in their IT environment with practical examples of implementations and opinions from IT managers.
The article describes various aspects of virtualization such as
- Hardware used
- Reasons to virtualize particular server
- Licensing issues
- System management
- Costs and benefits (aka Investments)
Personally I liked the article.
P.S. Meanwhile, Brien M.Posey wrote an excellent article on actual virtual machines deployment: The How's and Why's of Server Virtualization
