Challenge
-
Micro-services running on AWS ECS Fargate
-
RDS MySQL instances for each micro-service
-
To get better performance from RDS instances in terms of MySQL query operations
-
To reduce the cost of RDS instances
Solution
- In order to use Graviton for RDS MySQL instances, running MySQL version should be at least version 8. Therefore, our team upgraded the MySQL version of the instances from 5 to 8 first.
- In order to operate the migration with minimum downtime, our team got the advantage of the RDS Blue/Green Deployments feature.
With RDS Blue/Green deployments,
- We first created a Green environment from the existing RDS instances, including read replicas.
- Then we changed the RDS instance type to Graviton equivalent in the Green environment.
- And we completed the switch operation with minimum downtime, which is less than 1 minute!

Results
Graviton
All RDS instances have been moved to Graviton type.

Lower Resource Utilisation
As checked in the metrics, RDS instances perform better, and resource utilisation has decreased.

Cost Saving
The customer has the option to downgrade the RDS instance types for cost-saving purposes.
