This document provides an overview of the Apache Software Foundation (ASF) and how to get involved in Apache projects. It discusses that the ASF is a non-profit organization that provides legal, financial and infrastructure support for various open source projects. It operates under the "Apache Way", which is a meritocratic and consensus-based model. There are over 160 Apache projects spanning various technologies. The document then focuses on some integration-related projects, such as Apache ServiceMix, Camel, CXF and ActiveMQ. It provides guidance on how individuals can start contributing, such as by fixing bugs, writing documentation or testing code.

- 14. 2. How does it work? The Apache Way
- 15. The Apache Way ✗ A method of developing software ✗ A method of running communities ✗ A method of governing a Foundation ✗ Although the term is deprecated, The Apache Way relates to how the ASF (and its projects) work and operate ✗ Basically, the least common denominators on how PMCs operate
- 17. 3. Who does this work? Apache Projects
- 18. Apache Projects ✗ Responsible for their own code, community and direction ✗ Board provides oversight, but has no say on what code gets written, what direction projects take, what new projects we should start etc ✗ Foundation provides support (e.g. infra, branding, press) so that projects can focus just on their code + community
- 19. Apache Projects ✗ Over 160 top-level projects (TLPs) ✗ Diversity: Java, C, C++, Perl, … ✗ Leading technology ✗ Web servers, Java tools & stacks, search, cloud, big data, build tools, CMS/web framework, databases, OSGi containers, integration frameworks, graphics, … ✗ And end user Office suites! ✗ Over 40 projects currently in “pipeline”
- 20. Apache Projects ✗ It’s okay for projects to be in “same” space ✗ Ant/Maven, Pig/Hive, Axis/CXF... ✗ “Competing” project technology is OK ✗ If an active community following the Apache Way wants to join, great!
- 21. Apache Projects
- 22. Who pays? ✗ Apache does not pay for development ✗ Voluntary contributions only! ✗ Many (not all!) developers are paid by a third-party to work on the project ✗ Foundation bears indirect support costs ✗ Infrastructure, publicity, etc.
