Question

You are managing an application deployed on Cloud Run. The development team has released a new version of the application. You want to deploy and redirect traffic to this new version of the application. To ensure traffic to the new version of the application is served with no startup time, you want to ensure that there are two idle instances available for incoming traffic before adjusting the traffic flow. You also want to minimize administrative overhead. What should you do?

Options

  • AEnsure the checkbox "Serve this revision immediately" is unchecked when deploying the new
  • BConfigure service autoscaling and set the minimum number of instances to 2.
  • CConfigure revision autoscaling for the new revision and set the minimum number of instances to
  • DConfigure revision autoscaling for the existing revision and set the minimum number of instances

Explanation

In Cloud Run, setting the minimum number of instances ensures that a specified number of container instances are pre-warmed and ready to serve traffic immediately - this removes cold start latency. You need to apply this setting specifically to the new revision before redirecting traffic, which ensures two idle instances are ready. This approach minimizes administrative overhead by using native autoscaling settings rather than manual traffic simulation.
