Amazon OpenSearch Serverless - Amazon OpenSearch Service

Amazon OpenSearch Serverless

Amazon OpenSearch Serverless is an on-demand, auto-scaling configuration for Amazon OpenSearch Service. Unlike provisioned OpenSearch domains, which require manual capacity management, an OpenSearch Serverless collection automatically scales compute resources based on your application's needs.

OpenSearch Serverless offers a cost-effective solution for workloads that are infrequent, intermittent, or unpredictable. It optimizes costs by automatically scaling compute capacity based on your application's usage. Serverless collections use the same high-capacity, distributed, and highly available storage volume as provisioned OpenSearch Service domains.

OpenSearch Serverless collections are always encrypted. You can choose the encryption key, but you can't disable encryption. For more information, see Encryption in Amazon OpenSearch Serverless

Benefits

OpenSearch Serverless has the following benefits:

  • Simpler than provisioned – OpenSearch Serverless removes much of the complexity of managing OpenSearch clusters and capacity. It automatically sizes and tunes your clusters, and takes care of shard and index lifecycle management. It also manages service software updates and OpenSearch version upgrades. All updates and upgrades are non-disruptive.

  • Cost-effective – When you use OpenSearch Serverless, you only pay for the resources that you consume. This removes the need for upfront provisioning and overprovisioning for peak workloads.

  • Highly available – OpenSearch Serverless supports production workloads with redundancy to protect against Availability Zone outages and infrastructure failures.

  • Scalable – OpenSearch Serverless automatically scales resources to maintain consistently fast data ingestion rates and query response times.
