In an era of tight IT budgets, complex multitier computing
infrastructures, and dynamic and fast-changing business
and user needs, virtualization offers many potential benefits: lower hardware and maintenance costs, higher CPU
utilization, simplified systems management, high reliability,
and easy deployments, to name a few. IT organizations have
deployed virtualization technology to realize server consolidation, but they’re also looking for the benefits that virtualization can deliver to their business applications.
“The killer app for virtualization has been server consolidation,” says Al Gillen, program vice president for systems software
at market research firm International Data Corporation (IDC).
