CloudStack is an open source cloud computing software for creating, managing, and deploying infrastructure cloud services. It uses existing hypervisors such as KVM, VMware vSphere, and XenServer/XCP for virtualization. In addition to its own API, CloudStack also supports the Amazon Web Services (AWS) API[3] and the Open Cloud Computing Interface from the Open Grid Forum.[4]

History

CloudStack was originally developed by Cloud.com, formerly known as VMOps.[5] 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.[6] Cloud.com and Citrix both supported OpenStack, another Apache-licensed cloud computing program, at its announcement in July 2010.[7]

Citrix purchased Cloud.com on July 12, 2011, for approximately $200 million.[8][9] In August 2011, Citrix released the remaining code under GPLv3 and continued moving towards more open processes.[6] In February 2012, Citrix released CloudStack 3.0. Among other features, this added support for Swift, OpenStack's S3-like object storage solution.[10] In April 2012, Citrix donated CloudStack to the Apache Software Foundation (ASF), where it was accepted into the Apache Incubator; Citrix changed the license to the Apache License version 2. As part of this change, Citrix also ceased their involvement in OpenStack.[11] On November 6, 2012, CloudStack 4.0.0-incubating was announced,[12] the first stable release after joining ASF. On March 20, 2013, CloudStack graduated from Apache Incubator and became a Top-Level Project (TLP) of ASF.[13] The first stable (maintenance) release after graduation is CloudStack 4.0.2.[14]

  • Hyper-V 2012 R2
  • CentOS 6.2+ and 7.1 with KVM

BareMetal Hosts

  • RHEL or CentOS, v6.2 or 6.3 and 7.1
  • Fedora 17
  • Ubuntu 12.04

Deployment Architecture

The minimum production installation consists of one machine running the CloudStack Management Server and another machine to act as the cloud infrastructure (in this case, a very simple infrastructure consisting of one host running hypervisor software). In its smallest deployment, a single machine can act as both the Management Server and the hypervisor host (using the KVM hypervisor).[15]

Multiple management servers can be configured for redundancy and load balancing, all pointing to a common MySQL database.

Users

Apache CloudStack has a number of users.[16][17] In July 2012 it was reported that Datapipe launched the largest international public cloud to be built on CloudStack, which included 6 data centers in the USA, Britain, and Asia.[18]
