I would like to create my own private cloud, hosted on my servers, which can be Windows or Linux but I would like to use .NET/WCF in the service layer. I don't need a fancy/schmancy UI like Azure and I don't want use Amazon either. The data will be large i.e. images, video and lossless audio.

I know Hadoop/MapReduce is a central component to creating a cloud OS, what else is required?

Look, I know I cannot compete with Azure or Amazon, but I need a far smaller similar version of those services, how would you go about it?

Define "private cloud".

What do you need to do with it? What are the requirements? What makes you think that distributed massive storage components are required in your case?
