Amazon Elasticsearch Service has a new name: Amazon OpenSearch Service. This change coincides with the addition of support for OpenSearch 1.0. You can now run and scale both OpenSearch and Elasticsearch (until version 7.10) clusters on Amazon OpenSearch Service and get all of the same benefits you have enjoyed so far from Amazon Elasticsearch Service.

OpenSearch 1.0, is a community-driven, open source search and analytics suite derived from Apache 2.0 licensed Elasticsearch 7.10.2 & Kibana 7.10.2. It consists of a search engine, OpenSearch, and a visualization and user interface, OpenSearch Dashboards. With OpenSearch 1.0, we are adding support in Amazon OpenSearch Service for several new features such as transforms, data streams, and notebooks on OpenSearch Dashboards. To learn more about OpenSearch and the latest version, please refer to

Along with OpenSearch 1.0, we continue to support legacy Elasticsearch versions until 7.10 on the service. You can upgrade your existing Elasticsearch clusters on Amazon OpenSearch Service to OpenSearch 1.0, similar to how you upgrade to newer Elasticsearch versions. We have changed our configuration APIs to make them generic (e.g. CreateElasticsearchDomain to CreateDomain) and launched a new SDK version. We have maintained backward compatibility to help you continue to operate your cluster and to make this renaming as seamless as possible for you. As we roll out this name change, you will start noticing the new service name Amazon OpenSearch Service, as well as new resource types for OpenSearch, in consoles of various Amazon Web Services services, in documentation, and in APIs. Please refer to the FAQs for more information and the documentation to get a summary of the changes related to this rename.

OpenSearch 1.0 on Amazon OpenSearch Service is now available in 25 regions globally, including the Amazon Web Services China (Beijing) Region, operated by Sinnet, and the Amazon Web Services China (Ningxia) Region, operated by NWCD. Please refer to the Amazon Web Services Region Table for more information about Amazon OpenSearch Service availability.
