Currently Cloud Run only supports the `runLatest` mode of the Knative Serving spec (https://github.com/knative/serving/blob/master/docs/spec/spe...) but we're working on other modes (e.g. `release`) which would allow for traffic splits.
Doesn't App Engine Flex essentially help you run an app in a container and handle scaling too?
For example, what if you're running a stateless JVM app like something on Play Framework. Could you run it on either App Engine Flex or Cloud Run, and if so, what considerations would there be for choosing one over the other?
1. Flex runs directly on VMs (sharing some GCE networking, access to GPUs, etc.), Run doesn't.
Those are the two that come up top of mind. We're working on a more comprehensive "choose your compute product" walkthrough in the near future.
It sounds like there's a bit of overlap. If I'm not up and running yet and just want the most managed solution (least work to run, with the most powerful high level features), is one of these a clear choice?
In my case, I don't care as much about low level access, but I just want my app to run quickly and efficiently. App Engine Flex's ability to run multiple services within an application, get load balancing set up, have versions of the app for testing and rollbacks, etc seems great. However, overall I just want to the easiest way to run my stateless set of services.
I noticed that the console shows a traffic percentage for each revision, but no apparent way to change it. Any plans to support traffic splitting, or at least a one-click way to re-activate (or re-deploy) an older revision?
