# Loading streaming data into Amazon OpenSearch Service
<a name="integrations"></a>

You can use OpenSearch Ingestion to directly load [streaming data](http://aws.amazon.com/streaming-data/) into your Amazon OpenSearch Service domain, without needing to use third-party solutions. To send data to OpenSearch Ingestion, you configure your data producers and the service automatically delivers the data to the domain or collection that you specify. To get started with OpenSearch Ingestion, see [Tutorial: Ingesting data into a collection using Amazon OpenSearch Ingestion](osis-serverless-get-started.md).

You can still use other sources to load streaming data, such as Amazon Data Firehose and Amazon CloudWatch Logs, which have built-in support for OpenSearch Service. Others, like Amazon S3, Amazon Kinesis Data Streams, and Amazon DynamoDB, use Amazon Lambda functions as event handlers. The Lambda functions respond to new data by processing it and streaming it to your domain.

**Note**  
Lambda supports several popular programming languages and is available in most Amazon Web Services Regions. For more information, see [Getting started with Lambda](https://docs.amazonaws.cn/lambda/latest/dg/lambda-app.html) in the *Amazon Lambda Developer Guide* and [Amazon service endpoints](https://docs.amazonaws.cn/general/latest/gr/rande.html#lambda_region) in the *Amazon Web Services General Reference*.

You can send data from Amazon IoT using [rules](https://docs.amazonaws.cn/iot/latest/developerguide/iot-rules.html). To learn more, see the [OpenSearch](https://docs.amazonaws.cn/iot/latest/developerguide/opensearch-rule-action.html) action in the *Amazon IoT Developer Guide*.
