Note: Due to the variation in actual cloud requirements, different deployment model (private, public, hybrid) and use cases (IaaS, PaaS etc) the matrix will only list the available products and capabilities. It will not list evaluations (green, amber, red) rather than providing the information that will help you to evaluate it for YOUR environment.
After the acquisition of Cloud.com in July 2011, Citrix has centered its cloud capabilities around its CloudPlatform suite.
Citrix CloudPlatform (latest release 4.3.0.2) powered by Apache CloudStack - is an open source cloud computing platform that pools computing resources to build public, private, and hybrid Infrastructure as a Service (IaaS) clouds. CloudPlatform manages the network, storage, and compute nodes that make up a cloud infrastructure. Use CloudPlatform to deploy, manage, and configure cloud computing environments.
