Building a Private Cloud
Private clouds are currently one of the most popular concepts in cloud computing. They promise the flexibility of cloud infrastructures without sacrificing the control of owning and maintaining your own data center. For a definition of cloud architectures see my previous blog on Cloud Types (http://www.definethecloud.net/?p=109.) Private clouds are an…

Part of the reason for this disparity in thinking is that there is no ‘one size fits all solution.’ The other part…
