AWS RDS mySQL - visible only t3, r5 and m5 instance types.

Question

Hi,
I try to create mySQL RDS DB t4g but I see only t3, r5 and m5 instance types.
Can it be a bug with my account?

Accepted Answer

Hi.

What version of MySQL did you specify?  
t4g requires MySQL 8.0.25 or higher for RDS.

Answer

What configuration are you using? Availability depends on configuration, including region and deployment options (cluster, instance, etc.) to name a few.

I've confirmed in us-east-1, us-east-2, us-west-1, and us-west-2 that t4g instances are available for MySQL. For other regions, check [this documentation](https://aws.amazon.com/rds/mysql/pricing/).

Another note is that the RDS creation wizard defaults to a `Multi-AZ DB Cluster` deployment type, which does not appear to support burstable instance types (T3, T4g, etc).
