Apache Projects are a collection of open-source software initiatives managed by the Apache Software Foundation. These projects cover a wide range of applications, including web servers, data processing, and cloud computing, allowing developers to collaborate and share their work freely. Each Apache Project is developed by a community of volunteers who contribute code, documentation, and support. Popular examples include Apache HTTP Server, which powers many websites, and Apache Hadoop, used for big data processing. The foundation promotes a collaborative environment, ensuring that software remains accessible and continuously improved.
