Correct me if I'm wrong, but these are actually not close to Cloud Run. Cloud Run's differentiator is its scaling metric; it scales with incoming requests, and has strict configuration to assert that each replica only handle N concurrent requests. You could maybe get something like this set up on ACI or Fargate, but it'd require stringing together five or six different products. You can also definitely wire up those to autoscale on CPU%, but (1) this is not scale-to-zero, and (2) CPU% kinda sucks as a scaling metric, right? Idk I've never been happy with systems that autoscale on CPU%.
