It is not 0, it is just that if you manage cloud run and cloud spanner you don't manage all the other things you have to manage when you self host, and managing cloud run and spanner is really not a lot of effort, it is a lot less effort than managing a standalone database at least. > You also have to add the cost of adapting your solution to their infrastructure, which is not trivial either. Cloud run can run stock standard docker containers, you will have a bad time if your processes are not stateless though, and you will have the best time if you have a 12-factor app, but I would not count that as adapting to infrastructure. And you can use AlloyDB if you want Postgres.

> I'm fairly sure that google does a better job keeping cloud spanner and cloud run working, and their redundancy mechanisms working, than whoever runs your single linux box will do. Most of the uptime loss won't come from your provider but from your applications and configuration. If you use Cloud Run and mess up the configuration for the redundancy, you'll still have downtime. If your application doesn't work well with multiple instances, you'll still have downtime. > Keeping a whole linux box running is more complicated and requires more maintenance than Cloud Run and Cloud Spanner. Is it? I keep quite some linux boxes running and they don't really require too much maintenance. Not to mention that when things do not work, I have complete visibility on everything. I doubt Cloud Run provides you with full visibility. > It is not 0, it is just that if you manage cloud run and cloud spanner you don't manage all the other things you have to manage when you self host, and managing cloud run and spanner is really not a lot of effort, it is a lot less effort than managing a standalone database at least. Managing a simple standalone database is not a lot of effort. For most cases, specially the ones that can get away with running production on a single box, you'll be ok with "sudo apt install postgresql". That's how much database management you'll have to do. > Cloud run can run stock standard docker containers, you will have a bad time if your processes are not stateless though, and you will have the best time if you have a 12-factor app, but I would not count that as adapting to infrastructure. That definitely counts as adapting to infrastructure. For example, if I want to use Cloud Run my container should start fairly quickly, if it doesn't I need an instance running all the time which increases costs. I'm not saying Cloud Run/Spanner are bad. They'll have their use cases. But for simple deployments it's more complexity and more things to manage, and also more expensive. If doing "apt install postgres; git pull; systemctl start my-service" works and serves its purpose, why would I overcomplicate it with going to redundant systems, managed environments and complex distributed platforms? What do I stand to gain and at what cost?

You'd be surprised - the major cloud providers have outages all the time. Google in particular will have some random backing service firing 502's seemingly randomly while their dashboards say "all good".
