Open source at AWS

Since its inception, Amazon Web Services (AWS) has been the best place for customers to build and run open source software in the cloud. AWS is proud to support open source projects, foundations, and partners. We believe that open source is good for everyone and we are committed to bringing the value of open source to our customers, and the operational excellence of AWS to open source communities.

The best place to build and run open source software

AWS regularly contributes to many open source communities like Apache Software Foundation, the Linux Foundation, and more. Here are a few additional ways in which we support our open source ecosystem.

AWS has a responsibility to advocate for open source, which is core to the continued development of technology and the internet. We leverage our strengths and resources to improve the long-term health and security of the entire environment in which we’re operating.

AWS contributes to open source communities for the long haul. We contribute significantly to a large number of projects. Some well-known examples include Apache Airflow, Apache Cassandra, Apache Flink, Apache Hudi, Apache Kafka, Apache Lucene, Containerd, Kubernetes, OpenJDK, OpenTelemetry, PostgreSQL, Project Jupyter, Rust, and Valkey.

AWS works with open source partners to improve the operational experience for their customers. We help partners exceed customer expectations. We also support foundations such as the Eclipse Foundation, Cloud Native Computing Foundation, Open Source Security Foundation and many others.
