Announcing Amazon OpenSearch Serverless (Preview)
[Amazon OpenSearch Service](/opensearch-service/) now offers a new serverless option, [Amazon OpenSearch Serverless](/opensearch-service/features/serverless/). This option simplifies the process of running petabyte-scale search and analytics workloads without having to configure, manage, or scale OpenSearch clusters. OpenSearch Serverless automatically provisions and scales the underlying resources to deliver fast data ingestion and query responses for even the most demanding and unpredictable workloads. With OpenSearch Serverless, you pay only for the resources consumed. OpenSearch Serverless decouples compute and storage and separates the indexing (ingest) components from the search (query) components, with Amazon Simple Storage Service (Amazon S3) as the primary data storage for indexes. With this decoupled architecture, OpenSearch Serverless can scale search and indexing functions independently of each other, and independently of the indexed data in Amazon S3\. For example, when an application-monitoring workload receives a sudden burst of logging activities during an availability event, OpenSearch Serverless instantly scales the resources to ingest and store the data without impacting query response times. To get started with OpenSearch Serverless, developers can create new collections, a logical grouping of indexed data that works together to support a workload. OpenSearch Serverless supports the same ingest and query APIs as [OpenSearch](https://opensearch.org/), so you can get started in seconds with your existing clients and applications—all while building data visualizations with serverless [OpenSearch Dashboards](https://opensearch.org/docs/2.0/dashboards/index/). OpenSearch Serverless is now available in the following [AWS Regions](/about-aws/global-infrastructure/regional-product-services/): US East (Ohio), US East (N. Virginia), US West (Oregon), Asia Pacific (Tokyo), and Europe (Ireland). To learn more, see the [Amazon OpenSearch Serverless](/opensearch-service/features/serverless/) webpage and the [Amazon OpenSearch Service Developer Guide](https://docs.aws.amazon.com/opensearch-service/latest/developerguide/serverless.html).
