Difficulty: Easy
We identified several DynamoDB tables in your account with high storage costs relative to access costs. The Standard-Infrequent Access (IA) storage class offers 60% lower storage costs with a small increase in throughput costs. This is ideal for tables with high storage volume but infrequent access patterns.
Selection Criteria
Table to be in STANDARD storage class
The table has a high storage cost compared to the access cost ( ration > 0.5 )
The storage savings (60%) outweigh the 25% up in throughput cost (RCU / WCU)
