App Engine Backends API Shutdown

The Backends API was originally introduced as way to provide non user-facing compute, with longer timeouts, different instance sizes, etc.

Beginning in 2014, we started recommending Modules, which were eventually renamed to Services. During that time, we added backend instances (B_*) and scaling controls to all Services, thus removing much of the need for a separate Backends API.

On March 13, 2019, we will shut down the Backends API and all existing Backend versions. You will no longer be able to deploy new Backends or modify existing Backends, and these versions will stop serving traffic.

Migration

Please follow our migration guides for Python, Java, and Go to convert your Backends to Services.

If you need to run code for longer than 60 seconds, consider migrating to Cloud Tasks (10 minute timeout), Kubernetes Engine, or Compute Engine (indefinite).
