Bitnami is an open source project that produces open source installers or software packages for web applications and solution stacks as well as virtual appliances. Bitnami is sponsored by Bitrock a company founded in 2003 in Seville, Spain by Daniel Lopez Ridruejo. Bitnami stacks are used for installing software on Linux, Windows, Mac OS X and Solaris .
BitNami stacks are available for popular web applications such as WordPress, Drupal, Joomla!, and MediaWiki. In addition to the application itself, the stacks include the other software required to run that application. For example, a WordPress stack will include WordPress, as well as the MySQL database to manage data, Apache Web server to serve the pages, and phpMyAdmin to administer MySQL. BitNami installers are released under the Apache License 2.0.
Using automated cloud computing management, BitNami offers users automated application deployments of open source server apps from Amazon EC2 servers.
Since July 2009 BitNami also offers ready-to-run virtual machines.
The distinct difference between installation of BitNami installers and native installs (e.g. rpms and debs on Linux) are that they are installed in a way as to prevent interference with existing software and libraries. If multiple applications are installed on the same web server considerations for resolving conflicts on specific ports must be made.
On February 13, 2009, BitNami announced the release of the Enano CMS web stack , which is unique in that according to BitNami and to the Enano CMS Project, the stack module was the first to be externally developed.
On February 2010, BitNami announced the release of BitNami Cloud Hosting  a service that allows deploying BitNami stacks on the Amazon EC2 cloud, with automatic monitoring and backups.
