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 (IaaS) 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 IaaS 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).

CloudStack currently supports the most popular hypervisors:
VMware vSphere, KVM, XenServer, XenProject and Hyper-V as well as
OVM and LXC containers.

Users can manage their cloud with an easy to use Web interface, command line
tools, and/or a full-featured query based API.

For more information on Apache CloudStack, please visit the [website](https://cloudstack.apache.org)

## Who Uses CloudStack?

* There are more than 150 known organizations using Apache CloudStack (or a commercial distribution of CloudStack). Our users include many major service providers running CloudStack to offer public cloud services, product vendors who incorporate or integrate with CloudStack in their own products, organizations who have used CloudStack to build their own private clouds, and systems integrators that offer CloudStack related services.

* See our [case studies](https://cwiki.apache.org/confluence/display/CLOUDSTACK/Case+Studies) highlighting successful deployments of Apache CloudStack.

* See the up-to-date list of current [users](https://cloudstack.apache.org/users.html).

* If you are using CloudStack in your organization and your company is not listed above, please complete our brief adoption [survey](https://cloudstack.apache.org/survey.html). We're happy to keep your company name anonymous if you require.

## Demo

## Getting Started

* Download a released [version](https://cloudstack.apache.org/downloads.html)
* Build from source with the instructions in the [INSTALL.md](INSTALL.md) file.

## Getting Source Repository

Apache CloudStack project uses Git. The official Git repository is at:

https://gitbox.apache.org/repos/asf/cloudstack.git

And a mirror is hosted on GitHub:

https://github.com/apache/cloudstack

The GitHub mirror is strictly read only and provides convenience to users and
developers to explore the code and for the community to accept contributions
via GitHub pull requests.

## Notice of Cryptographic Software

This distribution includes cryptographic software. The country in which you currently
reside may have restrictions on the import, possession, use, and/or re-export to another
country, of encryption software. BEFORE using any encryption software, please check your
country's laws, regulations and policies concerning the import, possession, or use, and
re-export of encryption software, to see if this is permitted. See [The Wassenaar Arrangement](http://www.wassenaar.org/)
for more information.

The U.S. Government Department of Commerce, Bureau of Industry and Security (BIS), has
classified this software as Export Commodity Control Number (ECCN) 5D002.C.1, which
includes information security software using or performing cryptographic functions with
asymmetric algorithms. The form and manner of this Apache Software Foundation distribution
makes it eligible for export under the License Exception ENC Technology Software
Unrestricted (TSU) exception (see the BIS Export Administration Regulations, Section
740.13) for both object code and source code.

The following provides more details on the included cryptographic software:

* CloudStack makes use of JaSypt cryptographic libraries.
* CloudStack requires a MySQL-compatible database (MariaDB or MySQL), and uses native database encryption functionality.
* CloudStack makes use of the Bouncy Castle general-purpose encryption library.
* CloudStack can optionally interact with and control OpenSwan-based VPNs.
* CloudStack has a dependency on and makes use of JSch - a java SSH2 implementation.
