    Apache Software Foundation for an open-source community

    Weerawarana co-founded the Apache Software Foundation (ASF) in 1999, which is a non-profit organisation dedicated to the development of open-source software projects.    The ASF provides a collaborative environment for software developers to work together on various projects, adhering to the principles of transparency, meritocracy, and community-driven development.

    Under Weerawarana’s leadership, the ASF has grown to become one of the most influential organisations in the open-source community, overseeing the development of numerous widely-used software projects. Some of the most notable Apache projects include the Apache HTTP Server, Apache Tomcat, Apache Kafka, Apache Hadoop, and many others.

    Weerawarana himself has been involved in various Apache projects over the years, contributing his expertise in areas such as web services, middleware, and distributed computing.

    ASF is meritocratic, which means that membership in the Foundation is only awarded to volunteers who have made positive contributions to Apache projects. ASF is considered a second-generation open-source organisation because it provides commercial support without the risk of platform lock-in.

    The ASF aims to provide legal protection for volunteers working on Apache projects and to prevent the “Apache” brand name from being used by other organisations without permission. ASF also hosts several ApacheCon conferences each year to highlight Apache projects and related technologies.
