Commitment Discounts AWS - Not returning Recommendations for OpenSearch, Elasticache, DynamoDB

Products

• CloudHealth

Issue/Introduction

There are few circumstances in which Recommendations won't be made for existing infrastructure outlined below. 

 

Resolution

• Dynamo DB Recommendations are by nature Partial Upfront due to the Upfront + Hourly Payment that is made in purchased Reserved Capacity - https://aws.amazon.com/dynamodb/pricing/provisioned/
  
  In order to generate Recommendations please change the Payment Type to "Partial Upfront" to view Dynamo DB recommendations. 
  
  
• OpenSearch - There are number of Instance Types that do not have Reservations possible currently - https://aws.amazon.com/opensearch-service/pricing/#Reserved_Instance_pricing lists those Instance Types that do have recommendations possible.
  
  If the Instance Type doesn't appear under this section AWS Commitment Discounts won't recommend for that Instance Type e.g. - t2.medium.search doesn't appear in the above list.
  
  
• Elasticache -  A number of Node Types are now considered Previous Generation Node Types and will be listed under - https://aws.amazon.com/elasticache/previous-generation/ -> "Previous Generation Reserved Nodes for Amazon ElastiCache" 
  
  Previous Generation Reserved Nodes aren't possible to be purchased from AWS as of June 1, 2023 as mentioned under - https://aws.amazon.com/elasticache/previous-generation/ these Nodes won't have Recommendations made under AWS Commitment Discounts.
