Virtualization strategies
This document discusses virtualization strategies and trends. It outlines key IT challenges like simplifying management, reducing costs, and increasing security. Benefits of virtualization include reduced administration efforts, lower costs, improved resource utilization and increased availability. Server virtualization can enable server consolidation, support of multiple OS/applications, lab/deployment testing and disaster recovery. Application virtualization allows running incompatible applications in isolation. Planning for hardware virtualization involves ensuring appropriate licensing and addressing performance considerations.
