To reduce AWS RDS costs while maintaining the same I/O performance, it is recommended to use General Purpose SSDs instead of Provisioned IOPS SSDs for your RDS instances. This is a cost-effective storage option that is suitable for a broad range of database workloads, as long as your database does not require more than 10,000 IOPS or 160 MiB/s of throughput. By migrating Provisioned IOPS RDS instances to General Purpose instances, you can lower your monthly AWS bill without sacrificing performance. For example, if your MySQL database requires 150GB storage size and 1500 IOPS, you can save approximately $110 per month by using instances with General Purpose SSD storage instead of Provisioned IOPS SSD storage.Using General Purpose SSD storage means you only pay for storage, whereas Provisioned IOPS SSD storage requires payment for both storage and IOPS. If you are already using PIOPS-based databases, it is often possible to migrate them to General Purpose by configuring larger storage, which will provide higher baseline performance of IOPS at a lower cost.However, it is important to note that before migrating your RDS instances to General Purpose SSDs, it is highly recommended to back up your RDS database instances. This is because all automated backups (snapshots) associated with the instances will be removed once they are modified.
To ensure that your RDS instances are using General Purpose SSD storage and not Provisioned IOPS SSD storage, you can take the following remediation steps:
By following these remediation steps, you can ensure that your RDS instances are using cost-effective General Purpose SSD storage instead of Provisioned IOPS SSD storage. This will help to reduce your AWS costs without sacrificing performance.
