The Microsoft Private Cloud: A Technology Overview
Friday, October 14, 2011
I've said it before, and I'll say it again: If I ruled the world, I'd make using the phrase "private cloud" illegal. Obviously, though, I don't rule the world, and so this term has (sadly) become the standard way to describe using IaaS technology in your datacenter.
Confusing as it is, however, I'd argue strongly that there's a clear definition of "private cloud" that pretty much all analysts and vendors in this space agree on. It's not the same thing as ordinary virtualization, nor is it legitimate to start calling your datacenter a private cloud without making any changes. Instead, the core of a private cloud is IaaS--VMs on demand--along with perhaps other services, such as deploying applications. Most people want to use private clouds in their own datacenters, although some also want to link up with IaaS offerings from service providers.
To help clarify at least part of this story, I've written a Microsoft-sponsored white paper describing the private cloud technology embedded in System Center 2012. I've come to believe that anybody interested in cloud computing shouldn't ignore private clouds, if only because they're likely to be where a majority of cloud-focused money gets spent in the next couple of years. If you're interested in learning more about this technology area and the Microsoft approach in particular, the paper is available here
