OpenSearch is an independently governed, community-driven search and analytics platform — and since forking from Elasticsearch in 2021, it's built its own roadmap around vector search, hybrid query support, and security-by-default. Whether you're running self-managed clusters, evaluating Amazon OpenSearch Service, or migrating from Elasticsearch, the decisions that matter most are the ones made early: shard sizing, replica strategy, index template design, and how you handle index lifecycle. We use OpenSearch in production across observability, enterprise search, and AI-driven retrieval applications. Our OpenSearch consulting covers architecture, performance tuning, and full migration support.
