OpenSearch

OpenSearch is an open-source search and analytics suite designed for real-time data exploration, log analysis, and full-text search at scale. Originally derived from Elasticsearch and Kibana, it provides a community-driven alternative for indexing, querying, visualizing, and managing large volumes of structured and unstructured data. OpenSearch includes a powerful distributed search engine, a dashboarding interface (OpenSearch Dashboards), and a rich ecosystem of plugins for observability, security, alerting, and machine learning. It is commonly used for application monitoring, security information and event management (SIEM), and data analytics in cloud and enterprise environments, offering flexible APIs and compatibility with standard Elasticsearch clients and tooling.
