Over the last year I have been working on the CloudStack Open Source Cloud Computing project. This month we are getting ready to launch CloudStack 3.0 which really raises the bar for cloud computing platforms. So what is CloudStack? It is an infrastructure-as-a-service(IaaS) platform that orchestrates virtualized servers into an elastic compute environment. The project was originally developed by Cloud.com and is now sponsored by Citrix since they acquired Cloud.com in July of 2011.
