New Features

New AWS RI Recommendations, new Best Practice Checks  

CloudCheckr has built a new AWS RI Recommendation report for payer accounts that can be generated against the following services:  

  • Amazon EC2 (Elastic Compute Cloud) – For virtual server instances
  • Amazon RDS (Relational Database Service) – For managed relational databases
  • Amazon ElastiCache – For in-memory data caching
  • Amazon OpenSearch Service – For search and analytics workloads
  • Amazon Redshift – For data warehousing and analytics
  • Amazon MemoryDB for Redis – For Redis-compatible in-memory databases
  • Amazon DynamoDB – For NoSQL database workloads 

These recommendations will help you identify cost-saving opportunities by analyzing your historical usage and suggesting reservations that could reduce your on-demand spending. 

When generating these recommendations, the engine automatically excludes any instance usage that's already covered by existing Reserved Instances, Savings Plans or Spot Instances. This ensures that you receive recommendations only for the actual uncovered On-Demand usage. Specifically, EC2 RI recommendations are now aware of purchased savings plans and now take them into account during the recommendation process.  

If utilizing CMx, access the report by navigating to Home > Cost Savings > RI Recommendations. If utilizing Core, access the report by navigating to Cost > Reserved Usage > Recommendations > RI Recommendation. You can also search for RI Recommendations in the report search bar at the top of the application. 

This new report replaces the legacy RI Recommendations page, which had reduced levels of functionality relative to the new page.  

Prerequisites 

To get the new RI Recommendation page and the below BPCs to work as expected, the IAM Policy configured for your account must have the following permission: ce:GetReservationPurchaseRecommendation  

If this policy is not updated, you will receive an error message prompting you to update the IAM policy with the needed permission.  

New Best Practice Checks  

Along with a new AWS RI Recommendations report, we are releasing several new Best Practice Checks (BPCs) to all customers (Core and CMx users) related to these newly supported services, and additionally have updated existing BPCs to utilize the new recommendation engine. 

New BPCs: 

  • MemoryDB Reserved Instance Purchase Recommendations

  • DynamoDB Reserved Instance Purchase Recommendations 

Updated BPCs: 

  • RDS DB Instances Reserved Instance Purchase Recommendations 
  • EC2 Reserved Instance Purchase Recommendations
