In 2021, Amazon rebranded its Elasticsearch service to Amazon OpenSearch, marking a significant shift in the open-source search and analytics domain. This change came after Elastic NV, the original creators of Elasticsearch, modified their software licensing model. Amazon OpenSearch continues to be fully compatible with the original Elasticsearch and provides a suite of robust, scalable search and analytics capabilities. This rebranding signifies Amazon’s commitment to maintaining an open-source alternative while enhancing performance and reliability.
