OpenSearch Serverless collections are actually charged by hours?

0

I want to create a serverless collection of OpenSearch for testing, I've seen in many post people mentioning the price as 700$ minimun per month. My concern is: can I just create it for my tests, then delete it and just be charged for those hours the collection existed? This URL shows it charges by hour, but it worries me people warning it actually does not go off completely. How is that? https://aws.amazon.com/opensearch-service/pricing/ Please help me clarify these costs... Can I just create it for my tests, then delete it and just be charged for those hours the collection existed?

AOSS collection pricing is $0.24 per hour. For production use cases, you would need a minimum of 2 OCU (1 OCU per AZ) for ingestion and 2 OCU for Search/query - so a total of 4 OCUs. With 720 hours (30 days, 24 hours per day), that translates to roughly $691 per month. You can see more information on pricing here https://aws.amazon.com/opensearch-service/pricing/ But, if you delete the collection, you should get charged only for the hours your AOSS collection was used.

But we recently introduced new lower entry point for Amazon OpenSearch Serverless. https://aws.amazon.com/about-aws/whats-new/2024/06/amazon-opensearch-serverless-entry-cost-half-collection-types/

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. So, you will be paying half than the classic minimum workload.

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.
