Virtualization and over-subscription: breaking the 100% utilization barrier
I received an email from Andres Lagar-Cavilla about an interesting post from GridCentric, a virtualization startup.
Something that we think about a lot at GridCentric is how to ensure that resources are used efficiently. In fact, that’s what led us to create Copper in the first place — seeing how difficult it was to share large clusters amongst multiple users, groups or even software versions. We think that the ideas behind Infrastructure-as-a-Service have huge potential to revolutionize computing.
We realize that a lot of enterprises have focused on deriving maximum efficiency from their resources for a long time. I thought that I’d take a ground-up look at some of the mechanisms used by virtualization to do that, and introduce something that we’re developing for our next products in order to take resource multiplexing to the next level.
