Deploy to a specific AWS AZ?

I have some services in AWS in a particular AZ, and they are called from services in Render.

To minimize latency, it would be ideal if I could group them in the same AZ. Is it possible to choose an AZ for your services, and if not, is it something that is on the roadmap?

Not at the AZ level - that’s actually almost nearly impossible.

AZs are mapped randomly between accounts to prevent this exact behavior so a given Region/AZ isn’t overloaded.

From the AWS documentation:

To ensure that resources are distributed across the Availability Zones for a Region, we independently map Availability Zones to codes for each AWS account. For example, the Availability Zone us-east-1a for your AWS account might not be the same physical location as us-east-1a for another AWS account.
