What are the issues to watch out for?
• Software costs/Licensing: One of the largest issues to be aware of. Virtualization makes it easy to create new servers, but, each of those server environments require separate software licenses. If you are using open source, that server sprawl is merely something to be aware of; however, if you run proprietary server environments, that sprawl can quickly translate into high license fees. • Capacity planning: In order to realize the full benefits of virtualization, it is important to match hardware capabilities with server requirements. In practice, this comes down to fitting the greatest number of virtual servers onto a physical server without reducing the performance of those servers. • Training: Like any change or new product, introducing virtualization into the IT environment will require training. Businesses should factor that cost (both time and capital) into any virtualization plan. • Management: Though virtualizing servers does reduce the number of physical boxes, virtual mach
