are AWS EFS Mount Targets supported in AWS Local Zones?

Question

I am trying to create an EFS mount target in us-east-1-atl-1a AWS Local Zone using Terraform, but I received following error. I attempted to create it manually using UI, but I don't see an option to select us-east-1-atl-1a as an AZ(See screenshot). Does anyone know if this AWS Local Zone supports EFS mount targets? AWS Local Zone info page doesn't mention EFS at all.

Terraform Error:

Answer 1

EFS is not currently listed as a service available in Local Zones. You can see the list of services here - https://aws.amazon.com/about-aws/global-infrastructure/localzones/features/

EBS and FSx are the only storage options currently available.

Answer 2

This is not supported and only standard availablity zone are supported as the error indicated. "us-east-1a", │ "us-east-1b", │ "us-east-1c", │ "us-east-1d", │ "us-east-1f"
