Apache CloudStack™ is an open-source software system designed to deploy and manage large networks of virtual machines, as a highly available, highly scalable Infrastructure as a Service (IaaS) cloud computing platform.

Apache CloudStack is open-source software designed to deploy and manage large networks of virtual machines, as a highly available, highly scalable Infrastructure as a Service (laaS) cloud computing platform. CloudStack is used by a number of service providers to offer public cloud services, and by many companies to provide an on-premises (private) cloud offering, or as part of a hybrid cloud solution.

CloudStack is a turnkey solution that includes the entire “stack” of features most organizations want with an laaS cloud: compute orchestration, Network-as-a-Service, user and account management, a full and open native API, resource accounting, and a first-class User Interface (UI).

Users can manage their cloud with an easy to use Web interface, command line tools, and/or a full-featured RESTful API. In addition, CloudStack provides an API that’s compatible with AWS EC2 and S3 for organizations that wish to deploy hybrid clouds.

Apache CloudStack Infrastructure for Virtual Machines and Bare Metal. CloudStack can manage tens of thousands of physical servers installed in geographically distributed data centers. It is a powerful laaS management solution, but it is still easy to use and implement with a small team.

CloudStack is hypervisor agnostic, supporting VMware, KVM, XenServer and Xen Cloud Platform. This gives CloudStack a unique position in the market: it is not proprietary technology and is not tied to any specific infrastructure.
