So if there's something always running .... isn't the same as having on always on server (with auto scaling of some sort)?

[steren]

When a container is kept warm via " min-instances" but is not receiving requests ("idle"), its CPU costs 10x less than when it's actively processing requests, see pricing: https://cloud.google.com/run/pricing

[jkaplowitz]

I don't see the pricing for idle billable time disclosed on that site, only an indication that there is pricing. Am I missing it, or alternatively, could it be clarified?

[giovannibonetti]

Interesting, if an idle CPU costs 10x less, it ends up costing the same as 1 GB of memory, which amounts to about US$ 6/month each (Tier 1 pricing).

For an app with low usage, you start getting a price that can compete with Heroku.

[YawningAngel]

How is this cost saving achieved? At the risk of being reductive, surely the container is either in memory and ready to serve requests or it isn't?

[lights0123]

You still pay for RAM, just not CPU.

It seems they want to replace their managed AppEngine service through Cloud Run in the long run.

[justicezyx]

Cloud run is developed by the same team that built AppEngine. They share the same technical leadership and a lot of the technical stacks, for example, billing and security (gVisor).

I dont think it's that simple to replace one service with another. It requires a lot of very sensitive dealing with external customers. And one cannot (easily) use the typical "Google deprecation" on a Cloud service offering, either.

So it's complicated. But your impression is not too far from the inclination.

[nojvek]

I’d imagine google would at-least make both appEngine run on the same core primitives that cloud run uses. So while the public facing api is the same, the internals are replaced. At-least that’s how I’d approach it. Deprecate app-engine in that it will be infinitely supported until the last customer, but all new stuff is advocated to be used on cloud run.

[zadokshi]

This definitely appears to be their trajectory.

One would assume transition from AppEngine to Cloud Run would be directed by establishing a pricing differential that incentivises moving off AppEngine.

[shishy]

Yes but still marginally easier to get it up and running
