From the AWS open source blog:

Today, we are introducing the OpenSearch project, a community-driven, open source fork of Elasticsearch and Kibana. We are making a long-term investment in OpenSearch to ensure users continue to have a secure, high-quality, fully open source search and analytics suite with a rich roadmap of new and innovative functionality. This project includes OpenSearch (derived from Elasticsearch 7.10.2) and OpenSearch Dashboards (derived from Kibana 7.10.2). Additionally, the OpenSearch project is the new home for our previous distribution of Elasticsearch (Open Distro for Elasticsearch), which includes features such as enterprise security, alerting, machine learning, SQL, index state management, and more. All of the software in the OpenSearch project is released under the Apache License, Version 2.0 (ALv2).

Did you listen to our epic Elastic vs AWS episode on The Changelog? I’d really love to hear from the community on this subject…is this a good thing or a bad thing for open source at large? Why didn’t AWS just work with Elasticsearch (the company)?

We plan to rename our existing Amazon Elasticsearch Service to Amazon OpenSearch Service.
