description: |
|
|
Ensure Amazon RDS instances use General Purpose SSDs for cost-effective storage suitable for a wide range of workloads, except for applications needing over 10000 IOPS or 160 MiB/s throughput.
|
|
impact: |
|
|
Using Provisioned IOPS SSDs when not required can significantly increase AWS costs without providing necessary performance benefits.
|
|
remediation: |
|
|
Convert RDS instances from Provisioned IOPS to General Purpose SSDs to optimize costs without sacrificing I/O performance for most database workloads.
