Let's Get Virtual: A Look at Today's Server Virtualization Architectures

Abstract

In recent years, server virtualization has evolved from a technology with significant usage in development, training, and test environments to one that also has a viable place in the data center. Space and power limitations in the data center have fueled a large consolidation movement, with server virtualization and clustering at the forefront. While virtualization allows organizations to run multiple unique operating systems on the same physical host simultaneously, it also offers benefits in high availability and system portability. Naturally, the benefits come with tradeoffs. There is little room for error when it comes to managing data center resources. Understanding where each virtualization technology is best suited in the data center allows organizations to realize the benefits of virtualization without falling victim to its weaknesses.
