Invitation to private preview testing for App Engine Flex Private VMs (IPs)

[GCLB Serverless Contact]

You are invited to nominate your app to test a proposed feature for App Engine Flexible Private VMs

• What it does: It provides VMs with only internal IP addresses, and there is no external IP address.
• Benefits:  Regular ingress traffic will work using the regular URL, but without an IP address, it reduces risk for DDoS attacks (which can happen, regardless firewall settings!). It also saves you from getting external IP addresses.
• Additionally,  if the app needs internet access (egress), one needs to set-up Cloud NAT.

To apply for testing:

1. Collect the project IDs for projects you want to test with. These are strings: e.g. alpha-beta-123456, not the project numbers (all digits)
2. Enter the requested information in this form

What will happen when you apply:

If accepted, we will allowlist your project and we will share documentation on how to use this feature and provide feedback.

Thank you!

App Engine Flexible Team.
