So far, I really enjoy how the UI seems consistent, compared to AWS where different products seem like they are from a completely different service.
As for the products themselves, everything just works. For their Kubernetes platform, GKE, they provide an excellent UI to do almost anything. Auto scaling any workloads, deploying new workloads all through the UI (no manual YAML creation), performing rolling updates, it all just works.
Their Stackdriver product automatically logs all output from your GKE pods, and can even alert you with a concise summary of crashing errors (I caught a couple panics from a Go service with it).
Overall I’d say it’s been great so far, and much cheaper than AWS. I haven’t used Azure in any capacity, so I’m unsure how it would stack up.
