Why use OpenSearch?

OpenSearch is well-suited to the following use cases:

• Log analytics
• Real-time application monitoring
• Clickstream analytics
• Search backend

Component	Purpose
OpenSearch	Data store and search engine
OpenSearch Dashboards	Search frontend and visualizations
Security	Authentication and access control for your cluster
Alerting	Receive notifications when your data meets certain conditions
SQL	Use SQL or a piped processing language to query your data
Index State Management	Automate index operations
KNN	Find “nearest neighbors” in your vector data
Performance Analyzer	Monitor and optimize your cluster
Anomaly detection	Identify atypical data and receive automatic notifications
Asynchronous search	Run search requests in the background
Cross-cluster replication	Replicate your data across multiple OpenSearch clusters

Most OpenSearch plugins have corresponding OpenSearch Dashboards plugins that provide a convenient, unified user interface.

For specifics around the project, see the FAQ.

Docker quickstart

Docker {: .label .label-green }

1. Install and start Docker Desktop.

2. Run the following commands:

   docker pull opensearchproject/opensearch:{{site.opensearch_version}}
   docker run -p 9200:9200 -p 9600:9600 -e "discovery.type=single-node" opensearchproject/opensearch:{{site.opensearch_version}}
   

3. In a new terminal session, run:

   curl -XGET --insecure https://localhost:9200 -u admin:admin
   

To learn more, see Install and configure OpenSearch and Install and configure OpenSearch Dashboards.

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: your own certificates, your own authentication method, your own users, and your own passwords.
