There are many different good reasons for companies and organizations to invest in virtualization today, but it is probably safe to assume that financial motivation is number one on the list: virtualization can save a lot of money. Below is an overview of the key benefits of virtualization.
With technology budgets getting tighter, the advantages of running a number of operating systems and server functions virtually on one physical server instead of several can be compelling.
When does Server Virtualization Make Sense?
Virtualization is usually an ideal solution for applications such as Microsoft Exchange Server or interoffice file sharing and those that are meant for small or medium-scale usage. As a business grows, it is important to keep in mind that server virtualization is not recommended for use with high-performance applications where servers must be clustered together to meet performance requirements of just one application. In these situations the added overhead and complexity would reduce performance. Many industry experts suggest that you never let a server exceed 50% CPU (processor) utilization during the peak loads.
Multiple Operating Systems on One Computer
Server virtualization is a method of running multiple autonomous virtual operating systems on just one physical computer. It is an effective approach to maximizing both physical resources and the investment in hardware. Using the principle of virtualization, it is now possible to turn an inexpensive commodity server into 15 virtual servers running 15 virtual operating systems.
