Convert compatible RDS & Aurora Instances to Graviton

Opportunity Name:

Convert compatible RDS & Aurora Instances to Graviton

AWS Resource Type:

Amazon Relational Database Service (RDS) & Aurora

Opportunity Description:

Amazon Relational Database Service (RDS) and Aurora now support instance types powered by Graviton, which offer a better cost-performance ratio compared to their x86 counterparts. Graviton equivalents for RDS & Aurora instances offer 52% price-performance, and can effectively lower the instance costs of MySQL, Postgres and MariaDB databases.

Finder Criteria:

CloudFix identifies Aurora clusters which have exact Graviton equivalents (i.e., same burst capability, memory and vCPUs)  and have a Graviton-compatible version . It then excludes databases that have more than three months of reservations on the old instance type or databases with special configurations such as Global Databases and databases with custom endpoints.

Fixer Execution:

Once it has identified these easily fixable databases, the CloudFix fixer follows the upgrade process recommended by AWS. It avoids in-place upgrades to reduce downtime - instead, it creates a new node and swaps it out with the existing node.

For the writer node, Aurora failover is used to swap out the existing node during the maintenance window. After a day, the old nodes are deleted.

Potential savings (range in % on annual basis):

Graviton2 instances provide up to 52% price-performance improvement for RDS open-source databases depending on database engine, version, and workload. They also provide up to 35% price-performance improvement for Aurora depending on database size.

Can CloudFix implement the fix automatically once I accept the recommendation?

Yes, this conversion of RDS & Aurora instances from x86 to Graviton is automatic update once the Fixer Template is approved.

Is it possible to roll back once CloudFix implements the fixer?

One-click rollback is not possible but manual restore from snapshots is possible.

Does this fix require downtime?

No. CloudFix creates a new node and swaps out the existing node.

Do it yourself (DIY) Instructions:

If you have a CloudFix subscription, CloudFix will execute these upgrades for you. However, if you'd like to do it yourself, the steps for this manual upgrade are available on the AWS site.
