Amazon MemoryDB now supports AWS PrivateLink in GovCloud!

Hey everyone, it's me, Shiichan! Today I've got a slightly buttoned-up but important Amazon MemoryDB update for you!

AWS What's New aws.amazon.com

What was announced?

According to AWS What's New, Amazon MemoryDB now supports AWS PrivateLink in the AWS GovCloud (US-West) and AWS GovCloud (US-East) Regions. That means VPCs in either of these two GovCloud Regions can now reach MemoryDB privately.

Why it matters

AWS PrivateLink gives you private connectivity between VPCs, AWS services, and on-premises networks, without exposing that traffic to the public internet. GovCloud Regions serve government agencies and heavily regulated industries, where keeping network paths tightly closed and avoiding the public internet is already a strong requirement. Getting PrivateLink support here fills in a small but welcome piece for anyone running MemoryDB in these high-security environments.

What changes

All you need is an interface VPC endpoint, and applications inside your VPC can reach the MemoryDB APIs privately. And it's not limited to the VPC the endpoint lives in — you can also reach it from:

  • Other VPCs, via VPC Peering
  • On-premises environments, via AWS VPN or AWS Direct Connect

So teams running MemoryDB in GovCloud now have another option for keeping their network setup more closed off.

Dive Deep

Setup is straightforward: create an interface VPC endpoint for Amazon MemoryDB in your VPC using the Amazon VPC console, the AWS SDK, or the AWS CLI. From there, you just call the MemoryDB APIs through that endpoint as usual, and you've got a private connection.

Wrap-up

  • Amazon MemoryDB now supports AWS PrivateLink in AWS GovCloud (US-West) and AWS GovCloud (US-East)
  • Just create an interface VPC endpoint to reach MemoryDB without touching the public internet
  • You can also reach it via VPC Peering or AWS VPN / Direct Connect through that same endpoint

If you're running MemoryDB in GovCloud and have been wanting a more private connection path, this update is for you!
