Amazon EFS gets cross-account replication in AWS GovCloud (US)!

Hey there, it's Shii! Today I found an update to Amazon EFS. It's aimed at teams running on GovCloud, but it's a quietly helpful addition, so let me share it!

AWS What's New aws.amazon.com

What was announced?

This comes from AWS What's New: Amazon EFS now supports cross-account Replication in AWS GovCloud (US). With EFS Replication, you can automatically keep an up-to-date replica of your file system in another AWS account.

The story so far

Using multiple AWS accounts to isolate and manage business applications and data is a pretty common pattern, plenty of organizations split accounts for operational excellence, security, and reliability. Until now though, GovCloud (US) had no standard way to replicate EFS data to another account, so teams had to build their own sync processes.

What changes

With this update, you can now replicate an EFS file system to another account in any GovCloud (US) Region you choose. Not having to build your own sync process makes it much easier to meet business continuity, multi-account disaster recovery, and compliance requirements. You can set it up in just a few clicks, whether you use the Amazon EFS Console, AWS CLI, AWS CloudFormation, or the API.

Wrap-up

• Amazon EFS now supports cross-account Replication in AWS GovCloud (US)
• You can keep an up-to-date replica in another account without building your own sync process
• Set it up via the EFS Console, CLI, CloudFormation, or API

This is a quiet but useful update if your team runs multiple accounts on GovCloud, or if you work in a regulated industry that needs to meet compliance requirements!
