## 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]({{site.url}}{{site.baseurl}}/opensearch/) | Data store and search engine
[OpenSearch Dashboards]({{site.url}}{{site.baseurl}}/dashboards/) | Search frontend and visualizations
[Security]({{site.url}}{{site.baseurl}}/security-plugin/) | Authentication and access control for your cluster
[Alerting]({{site.url}}{{site.baseurl}}/monitoring-plugins/alerting/) | Receive notifications when your data meets certain conditions
[SQL]({{site.url}}{{site.baseurl}}/search-plugins/sql/) | Use SQL or a piped processing language to query your data
[Index State Management]({{site.url}}{{site.baseurl}}/im-plugin/) | Automate index operations
[KNN]({{site.url}}{{site.baseurl}}/search-plugins/knn/) | Find “nearest neighbors” in your vector data
[Performance Analyzer]({{site.url}}{{site.baseurl}}/monitoring-plugins/pa/) | Monitor and optimize your cluster
[Anomaly Detection]({{site.url}}{{site.baseurl}}/monitoring-plugins/ad/) | Identify atypical data and receive automatic notifications
[Asynchronous Search]({{site.url}}{{site.baseurl}}/search-plugins/async/) | Run search requests in the background

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

For specifics around the project, see the [FAQ](https://opensearch.org/faq/).

## Docker quickstart
Docker
{: .label .label-green }

1. Install and start [Docker Desktop](https://www.docker.com/products/docker-desktop).
1. Run the following commands:

   ```bash
   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}}
   ```

1. In a new terminal session, run:

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

To learn more, see [Install and configure OpenSearch]({{site.url}}{{site.baseurl}}/opensearch/install/) and [Install and configure OpenSearch Dashboards]({{site.url}}{{site.baseurl}}/dashboards/install/).


## 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]({{site.url}}{{site.baseurl}}/security-plugin/configuration/index/): your own certificates, your own authentication method, your own users, and your own passwords.
