CloudStack is an open source cloud computing software for creating, managing, and deploying infrastructure cloud services. It uses existing hypervisors such as KVM, VMware ESXi and XenServer/XCP for virtualization. In addition to its own API, CloudStack also supports the Amazon Web Services (AWS) API and the Open Cloud Computing Interface from the Open Grid Forum.

CloudStack was originally developed by Cloud.com, formerly known as VMOps.

Cloud.com was first registered in 1992 as a BBS system offering telnet, ftp, lynx, gopher and archie services, "Cloud City Online" by John Bilik in Lake Zurich, Il. The domain was hijacked several years later and sold multiple times.

A company called VMOps was founded by Sheng Liang, Shannon Williams, Alex Huang, Will Chan, and Chiradeep Vittal in 2008. The company raised a total of $17.6M in venture funding from Redpoint Ventures, Nexus Ventures and Index Ventures (Redpoint and Nexus led the initial Series A funding round). The company changed its name from VMOps to Cloud.com on May 4, 2010, when it emerged from stealth mode by announcing its product.Cloud.com was based in Cupertino, California.

In May 2010, Cloud.com released most of CloudStack as free software under the GNU General Public License, version 3 (GPLv3). They kept about 5% proprietary. Cloud.com and Citrix both supported OpenStack, another Apache-licensed cloud computing program, at its announcement in July 2010.
