Services or capabilities described in AWS documentation might vary by Region. To see the differences applicable to the AWS European Sovereign Cloud Region, see the AWS European Sovereign Cloud User Guide.

Mounting EFS file systems from another AWS account or VPC

You can mount your EFS file system using IAM authorization for NFS clients and EFS access points using the EFS mount helper. By default, the EFS mount helper uses domain name service (DNS) to resolve the IP address of your EFS mount target. If you are mounting the file system from a different account or virtual private cloud (VPC), you need to resolve the EFS mount target manually.

Following, you can find instructions for determining the correct EFS mount target IP address to use for your NFS client. You can also find instructions for configuring the client to mount the EFS file system using that IP address.
