The ability to virtualize application workloads has transformed IT and made application provisioning much faster. Organizations of all sizes, in all industries, have gained the cost benefits of being able to consolidate multiple application workloads on a few physical servers. This server virtualization has helped organizations to reduce capital expenses by minimizing the amount of hardware required. It has also reduced operational expenses as IT groups no longer need to manage hundreds or thousands of servers, each dedicated to its own application. Instead, IT teams can consolidate multiple Exchange, SQL, Web 2.0, e-commerce and other applications, each running in a virtual machine (VM) on fewer servers, using hypervisors such as those from VMware ®, Microsoft ® and Citrix ® .
