Amazon OpenSearch Serverless slashes entry cost in half for all collection types

Posted on: Jun 5, 2024

We are excited to offer a new lower entry point for Amazon OpenSearch Serverless, which makes it affordable to run small-scale search and analytics workloads. Opensearch Serverless’ compute capacity for indexing and searching data are measured in OpenSearch Compute Units (OCUs). Prior to this update, highly-available production deployments required a minimum of 4 OCUs with redundancy for protection against Availability Zone outages and infrastructure failures.

With the introduction of fractional 0.5 OCU, OpenSearch Serverless can be deployed starting at just 2 OCUs for production workloads. This includes 1 OCU for primary and standby indexing nodes at 0.5 OCU each, and 1 OCU total for search across two 0.5 OCU active replica nodes in separate Availability Zones. OpenSearch Serverless will automatically scale up the OCUs based on workload demand. Additionally, for dev/test workloads that don't require high availability, OpenSearch Serverless offers a 1 OCU deployment option, further cutting costs in half, with 0.5 OCU for indexing and 0.5 OCU for search.

The support for the new fractional 0.5 OCU for lowering the entry costs in OpenSearch Serverless is now available in all 11 regions globally: US East (Ohio), US East (N. Virginia), US West (Oregon), Asia Pacific (Singapore), Asia Pacific (Sydney), Asia Pacific (Tokyo), Europe (Frankfurt), Europe (Ireland), Europe West (Paris), Europe West (London), and Asia Pacific South (Mumbai).
