Rule Code: AWS-R-ES-02
Identify any pending Amazon Elasticsearch (ES) Reserved Instances available in your AWS account.
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.
Audit / Verification
Step 01: Sign in to AWS Management Console.
Step 02: Navigate to Elasticsearch (ES) dashboard, under Elasticsearch (ES). In the left navigation panel, select Reserved Instances.
Step 03: Choose the Reserved Instance (RI) that you want to examine and check the value listed within the Status column and check if the reservation current status is set to payment-pending.
Step 04: Repeat step no. 3 to verify the purchase status for other AWS Elasticsearch Reserved Instances provisioned in the current region.
Step 05: Change the AWS region from the navigation bar and repeat the process for other regions.
