The Stack Wars: OpenStack vs. CloudStack

Is it too confusing to have two different open cloud stacks? I guess not, as long as they’re clearly differentiated and targeted at different use cases…

Overall, CloudStack is better packaged for enterprise adoption, especially in environments not already familiar with open source. Its installation packaging and customizable admin/end-user portal are designed for quick, scalable adoption of the private cloud. OpenStack, on the other hand, can be best described as a foundation or framework for cloud computing, not nearly as polished.
