Apache Incubator is the starting point for projects and software seeking to become part of the Apache Software Foundation’s efforts.
Requirements to enter a project into the Incubator include a working codebase, the intention to donate copyright and intellectual property ownership to the ASF and sponsorship by a foundation member or officer.
The ASF uses the Incubator project to ensure projects are free from legal conflicts and compatible with the open source foundation's guiding principles. The intention is to decide by meritocratic processes which projects most deserve the foundation's support.
Projects that have been through the Incubator include:
- Apache HTTP server: a freely available Web server that runs on most operating systems including UNIX, Microsoft Windows, Mac OS/X and Netware.
- Cassandra: an open source distributed database system designed for the management of large amounts of data across commodity servers.
- CloudStack: a platform for delivery of Infrastructure-as-a-Service (IaaS) in cloud computing environments.
- Hive: an open-source data warehouse system for querying and analyzing large datasets stored in Hadoop files.
- Hadoop: a free, Java-based programming framework that supports the processing of large data sets in a distributed computing environment.
As with the rest of the ASF, the Incubator is a virtual entity and has no dedicated buildings and no employees, although it has, at this writing, 2663 volunteers.
