Cost effective AWS OpenSearch service for development

For a more cost-effective approach to using Amazon OpenSearch Service for development without creating a new free tier account, you have several options:

1. Consider using Amazon OpenSearch Serverless instead of provisioned instances. OpenSearch Serverless is cost-effective because you only pay for the resources you actually consume, eliminating the need for upfront provisioning or overprovisioning. This is particularly beneficial for development environments where usage may be intermittent.

2. If you need to stick with provisioned OpenSearch Service, implement Reserved Instances (RIs) which can provide significant discounts compared to On-Demand instances. Even for development purposes, if you know you'll be using the service consistently over the next 1-3 years, RIs essentially provide a billing discount on your instances.

3. Optimize your usage patterns by turning off your development cluster when not in use. Since you're billed hourly, this can significantly reduce costs.

4. Ensure you're using the right instance type for your development needs. While t3.small.search is already one of the smaller instance types, make sure you're not over-provisioning for your actual development requirements.

5. Monitor your usage and costs actively to identify any unexpected usage patterns that might be contributing to higher bills.

Remember that while t3.small.search instances are included in the AWS Free Tier (up to 750 hours per month), this doesn't apply to your account since you mentioned it's not a free tier account.

Into Free tier services it's shown as always free service but I'm charged for using it:

Maybe I don't understand something..........

I understand the confusion.

Some of our services have limits when it comes to our Free Tier plan. You can find more about those limits here.
