CloudStack is open-source Infrastructure-as-a-Service cloud computing software for creating, managing, and deploying infrastructure cloud services. It uses existing hypervisor platforms for virtualization, such as KVM, VMware vSphere, including ESXi and vCenter, XenServer/XCP and XCP-ng. In addition to its own API, CloudStack also supports the Amazon Web Services (AWS) API^[2] and the Open Cloud Computing Interface from the Open Grid Forum.^[3]
