Since you are using the Node.js runtime, you are deploying your application to the App Engine <https://cloud.google.com/appengine/docs> Flexible environment. By default, the minimum number of instances <https://cloud.google.com/appengine/docs/flexible/nodejs/configuring-your-app-with-app-yaml#automatic_scaling> for any GAE Flex app is set to '2'. This is why you are constantly seeing two instances serving your app.
You can edit your app.yaml <https://cloud.google.com/appengine/docs/flexible/nodejs/configuring-your-app-with-app-yaml#automatic_scaling> to deploy your app with a lower '*min_num_instances'. *Note that the hard minimum limit for App Engine Flexible apps is '1'. You can always stop or delete a version to completely removes its instances. If you instead wish to use a GAE Standard <https://cloud.google.com/appengine/docs> environment supported runtime, the hard minimum limit there is '0'. -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.
