When looking at a virtual technology such as Hyper-V, you have to ask yourself, "How will these two edicts be satisfied?" As a server virtualization technology, Hyper-V effectively offers users the ability to separate and share server resources amongst multiple VMs so that satisfies the virtualization piece. But how do we gain control so as to optimize resource usage and lower the total cost of ownership?
When used properly, we can all agree that virtualization is changing the datacenter in a positive way by providing operational and economic benefits. Yet virtualization by itself does not create economic benefits. After all, virtualization is just the ability to abstract and hide the physical computing resources through the creation of a virtual machine (VM) with no initial cost benefit in doing so. In fact, in many environments virtualization may increase costs long term due to the new licensing and administration overhead that VMs create.
To reel this in, we really need to remember the two main edicts of server virtualization:
- Eliminate under-utilized server machines that waste resources and increase the total cost of ownership
- Fully utilize through virtualization properly sized server machines to optimize resource usage while lowering the total cost of ownership
