Server virtualization is the partitioning of a physical server into smaller virtual servers to maximize your server resources. In server virtualization, the resources of the server itself are hidden, or masked from users and the software is used to divide the physical server into multiple virtual environments, called virtual or private servers. This is in contrast to dedicate one server to a single application or task. This technology brings positive transformations such as reduced hardware costs, improved server provisioning and deployment, better disaster recovery solutions, efficient and economic use of energy, and increased staff productivity to companies that adopt it. Industry will continue to adopt virtualization for many reasons: collections of inefficient servers can be replaced with fewer machines; software can be tested while isolated in harmless virtual partitions; and data centers can gracefully (and virtually) conform to shifting work models, new technologies and changing corporate priorities. The future of enterprise IT management will be based on virtual computing.
