How to remove opensearch instances from code? about fhir-works-on-aws

[Bingjiling]

Hi @nkundella,

Thanks for reaching out! I'm sorry to hear about the unexpected bill.

To better assist you with cost reduction, I have a few questions for you. What stage have you deployed FWoA in? How long did the deployed instance run? What functionalities have you tested in the instance?

As a quick mitigation, you can try deploying FWoA in the dev stage. FWoA is configured to create smaller OpenSearch instance to save on cost in dev stage(Link code link here). You should see a significant reduce in cost when you deploy FWoA in dev stage instead.

To answer your question in removing OpenSearch cluster from codes, you can delete this file in CDK construct that creates the OpenSearch clusterLink and any references to this file. Note this will break the search functionality of FWoA, and could bring other side effects.

Thanks,
Yanyu

Hi @nkundella, can I ask what version of FWoA this is using? These look like CDK Nag issues, meaning they are addressable by updating certain properties on resources in the CDK Code. For example, two of the first few issues involve the fhirLogsBucket construct and the glueScriptsBucket construct not having default encryption enabled. However, this is set as of the latest code here.

If you'd like to avoid checking the CDK resources with CDK Nag (not recommended as this may miss best practices for creating AWS resources when customizing FWoA), you can simply disable the checks here by commenting them out.

Thanks,
