OpenSearch Billing - Billed when nothing is running

Question

Hi,

We are trialling the AWS environment and we notice that we are being billed daily for the OpenSearch service even though nothing is running in the environment. This is around $45 per day.

Is this normal or is there something configured incorrectly?

Thanks for the help in advance.

Accepted Answer

You can review this by accessing to the Cost Explorer console , Filter by Opensearch Service . By filtering the usage type, you can further refine the charges.

Answer

Hi,

it depends on your usage, but it is probably expected. OpenSearch is not a 100% a serverless service per se, as it will not scale to zero( as typically lambda, for example, would do) and according to https://aws.amazon.com/opensearch-service/pricing/, once free tier is passed, then it runs per hour, so you will incur into costs.

Thus I would read this: https://repost.aws/knowledge-center/free-tier-charges to setup alarms to prevent getting charged after free tier.

Hope it clarifies ;)
