4. Virtualization of local networks in hypervisors

Our hosting provider is expanding its business, and the number of servers it hosts is growing rapidly, posing space, power supply and air-conditioning problems. What's more, our monitoring tools tell us that these servers are only using a minority of the hardware resources available to them.

The obvious solution is to virtualize its servers on a single physical machine. Numerous solutions exist on the market (VMware's vSphere, RedHat's REV, Xen, HyperV, KVM etc.), and our host has chosen VMware, the current market leader.

On the other hand, our host doesn't want to make any major changes to its network architecture, so the virtualization of its network into VLANs suits it perfectly and should be maintained using a hypervisor.
