1. The reason for manually scaled instances not having a 'Billed Instance Estimate' line in the App Engine Dashboard <https://console.cloud.google.com/appengine> 'instances' graph is due to the fact that you always pay for the amount of manually scaled instances you have set in your app.yaml (aka the blue 'Created' line). Therefore, instead of having two lines always equal to each other, it is cleaner to simply display one line.
2. The 'Active' instances line in the graph represents the amount of instances that are currently using resources to respond to your incoming requests. Where as the 'Created' line shows the amount of instances that are waiting to do work. 3. Unlike Manually scaling, Automatic scaling will start and stop instances for you based on your application requirements. It will therefore not charge you for 'Created' instances that have been idle for 15 minutes <https://cloud.google.com/appengine/docs/standard/python/how-instances-are-managed#instance_billing>. You will also not be charged for any 'Created' instances exceeding the amount of 'max_idle_instances' <https://cloud.google.com/appengine/docs/standard/python/config/appref#scaling_elements> that you set for each service. Therefore, the 'Billed Instance Estimate' line will appear for Automatic scaling in order to show you an estimate of what you are actually being charged (note that it is just a rough estimate based on averages and your actual bill will reflect the correct numbers). -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.
