Virtualization in the large enterprise

Fortune 500 companies typically have a heavy dependence on technology. Hundreds of servers running internal applications and major web farms running internet facing customer applications. It is not unusual to find a marked disparity between the inward and outward facing applications. What drives this disparity? Typically the budget process is a major contributor. Budget equates to ownership. Ownership discourages sharing of equipment. This therefore leads to islands of applications. What is needed to break this cycle of isolated computing is to take some of the web 2.0 concepts that are emerging and apply them to the budget and service provisioning process.
