Why use OpenSearch?

Fast, scalable full-text search	Application and infrastructure monitoring	Security and event information management	Operational health tracking
Help users find the right information within your application, website, or data lake catalog.	Easily store and analyze log data, and set automated alerts for performance issues.	Centralize logs to enable real-time security monitoring and forensic analysis.	Use observability logs, metrics, and traces to monitor your applications in real time.

Key features

OpenSearch provides several features to help index, secure, monitor, and analyze your data:

• Anomaly detection – Identify atypical data and receive automatic notifications.
• SQL – Use SQL or a Piped Processing Language (PPL) to query your data.
• Index State Management – Automate index operations.
• Search methods – From traditional lexical search to advanced vector and hybrid search, discover the optimal search method for your use case.
• Machine learning – Integrate machine learning models into your workloads.
• Workflow automation – Automate complex OpenSearch setup and preprocessing tasks.
• Performance evaluation – Monitor and optimize your cluster.
• Asynchronous search – Run search requests in the background.
• Cross-cluster replication – Replicate your data across multiple OpenSearch clusters.

The secure path forward

OpenSearch includes a demo configuration so that you can get up and running quickly, but before using OpenSearch in a production environment, you must configure the Security plugin manually with your own certificates, authentication method, users, and passwords. To get started, see Getting started with OpenSearch security.
