c6a instance types for Batch compute environments

Question

Hi, I don't seem to be able to select the new c6a EC2 instance types for AWS Batch compute environments from the console (Ireland region). I haven't tested using the API. The instance type is available to launch as a separate EC2 instance. My workload is largely single threaded so I would prefer the fastest possible single vCPU performance.

I'm guessing this is just not configured properly yet, but I'm only on basic support so can't raise a technical support ticket about that. Or can anyone advise if it's a regional or technical limitation instead?

Answer

m6a is available for AWS Batch and may be your best option for now. We have a feature request which may allow selection of additional instance types (such as c6a) sooner after they're available in ec2. We don't yet have a timeline when that feature may be released.
