The bigger question, for me, was: Why not use GCP instead of AWS, if you're running Kubernetes, a Google project that GCP is especially friendly towards?
Interesting! I would've thought Kubernetes on GKE would be the one offering Google's platform totally dominated - even if you have a lot of your other infrastructure on AWS.
I'm just getting started w Kubernetes and had seen some comments that I should be using GKE - so this was counterintuitive to me. I guess that once you get set up and running, AWS's offering is comparably good.
