Identify any pending Amazon Elasticsearch (ES) Reserved Instances available in your AWS account and solve these incomplete ES reservations by requesting AWS Support to retry the necessary payments, as outlined in the remediation/resolution section of the conformity rule. A pending AWS Elasticsearch Reserved Instance is an incomplete reservation that receives the "payment-pending" status during the purchasing process due to issues with the payment method used by the AWS customer.
This rule can help you work with the AWS Well-Architected Framework
This rule resolution is part of the Cloud Conformity Cost Management tool for AWS
Using Reserved Instances to cut down on computing costs is one of the best cost optimization strategies when working with AWS Elasticsearch service. To fully receive the discount benefit, make sure that all your Elasticsearch reservation purchases have been fully processed (i.e. the purchase has been approved and the payment has been confirmed).
To identify any pending AWS Elasticsearch RI purchases available within your AWS account, perform the following:

To solve any incomplete Amazon Elasticsearch reservations, you need to retry the RI payments by contacting Amazon Web Services. To create the required support case using the AWS Support Center console, perform the following:Note: Requesting Amazon to retry pending Elasticsearch Reserved Instance payments using AWS Billing and Cost Management console or AWS API via Command Line Interface (CLI) is not currently supported.
