Amazon launched their ARM-based chip, nicknamed Graviton, within the last few years. Since its release AWS customers have been showing major interest in the chip for its better price-to-performance ratio. Oftentimes, the main point of discussion for leveraging Graviton processors is around EC2 as that tends to be the top cost-center for organizations.
However, Amazon has been making a major push to have other managed services, such as RDS and ElasticSearch, offer Graviton processors. Where normally there are considerations when looking to run workloads on ARM to ensure that your application isn’t impacted, these go away when leveraging AWS-managed services. As a result, this can be a very quick win from a savings perspective and have the added benefit of better performance as well.
How much you can save depends on what RDS instance you’re currently running on. Though in general, you can look to save around 10% of your bill when going from the previous generation x86 chip to the newer generation Graviton processor. Below is an example, using us-east-1 prices for a multi-AZ RDS deployment:

To see a comparison of what RDS instance you’re currently running and what an equivalent Graviton based price would be, check out the “RDS” section of ec2instances.info.
AWS makes migrating to Graviton is very straight-forward and there are only a few considerations you’ll need to make before planning to move forward:
To get started with the above, feel free to visit ec2instances.info to see your potential savings or take a look at the AWS CLI command for modifying instances on RDS here: https://docs.aws.amazon.com/cli/latest/reference/rds/modify-db-instance.html
