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

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.
