# Amazon OpenSearch Serverless
Integration version1.0.0
## Overview{% #overview %}

Amazon OpenSearch Serverless is an on-demand serverless configuration for OpenSearch, providing an easy way to query and analyze large volumes of data. OpenSearch Serverless collections provide the same benefits as self-managed clusters, without the added complexity of configuration and tuning.

Vector search collections are specifically designed for high-performance similarity searches in machine learning (ML) and artificial intelligence (AI) applications, and can be used to automatically create knowledge bases on Bedrock.

## Setup{% #setup %}

### Installation{% #installation %}

If you haven't already, set up the [Amazon Web Services integration](https://docs.datadoghq.com/integrations/amazon_web_services.md) first.

### Configuration{% #configuration %}

1. In the [AWS integration page](https://app.datadoghq.com/integrations/amazon-web-services), ensure that OpenSearch Serverless is enabled under the **Metric Collection** tab.
1. Install the [Datadog - Amazon OpenSearch Serverless integration](https://app.datadoghq.com/integrations/amazon-opensearch-serverless).
