Today's data center managers often control networks populated by hundreds of servers, and often each server runs just one application and requires its own management console. This server glut has made administration a logistical nightmare, and IT managers have told us -- in surveys and interviews -- that they're exploring ways to move server workloads onto fewer servers. In the past, logical partitioning and clustering were the primary consolidation tactics. Today, virtualization promises a more robust and flexible alternative.
Virtualization combines software and hardware to support multiple applications and operating systems running on a single server, while isolating one workload from another. As a result, server utilization levels are increased, and the number of servers needed to support applications is reduced.
