Startups and enterprises are increasingly using open source projects for architectures. AWS customers and partners also run their own open source programs and contribute key technologies to the industry (see DCS201). At AWS, we engage with open source projects in several ways. Through bug fixes and enhancements to popular projects, including work with the Hadoop ecosystem (see BDM401), Chromium (see BAP305) and Boto, and standalone projects like the security library s2n (see NET405) and machine learning project MXNet (see MAC401). We have services like Amazon ECS for Docker (see CON316) and Amazon RDS for MySQL and PostgreSQL (see DAT305) that make open source easier to use. In this session, learn more about existing AWS open source work and our next steps.
