Hello Artur, You may consider switching to other instance class, such as F2, all depending on your application's needs, and your design decisions. You can not readily refer to practice, all depending on your application. You set instance class in app.yaml. Details are available on the "App Engine Standard Environment" page <https://cloud.google.com/appengine/docs/standard/#instance_classes>.
You may check how come your app has become popular by reading its relevant logs. One has access to logs through Developers' Console. A possible explanation for your app's activity might come from side of health checking. The environment verifies periodically that your app is up and running by sending specific requests. You can configure health checking in the app.yaml configuration file <https://cloud.google.com/appengine/docs/flexible/python/reference/app-yaml#health_checks>. The entry looks similar to: health_check: enable_health_check: True check_interval_sec: 5 timeout_sec: 4 unhealthy_threshold: 2 healthy_threshold: 2 Related to your point 2: you may consider changing mentioned parameters in accordance with your needs. You can establish your app's needs by checking relevant information items from Developers' Console, and set up Stackdriver Monitoring <https://cloud.google.com/monitoring/> to get even more detail. You can use this information to determine that your app needs more memory or disc size, if usage is proven high for these resources. -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.
