Just mentioning, i didn't knew Google Cloud does the .Net stack also. But i haven't had any bad experience with Azure ( small webapps, not huge ones). ( i chose Azure over Amazon)

I just publish and run. Some web apps have been running for over 4 years, without me touching it and paying customers ( 1-10). I only had one small "downtime" moment, but it was over after 15 minutes.

I wouldn't expect anything more from where i host it. The biggest annoyance i had was the redesign of the dashboard, which had me confused for a while ( it changed a lot, so that's normal), then again, i don't hate change. I switched to the new interface asap.
