So, I can set min_idle_instances in app.yaml instead of ping the instance every 5 mins. Is it right?
I actually made a test. I hit my instance *every second*. My daily quota ends in 8 hours, and I've consumed 16,29 of 28 instance hours in 47.165 requests. It's worth to say that I'm only returning a "hello world" message, nothing heavy.
