Unfortunately, this is NOT really about Kubernetes - this is about GKE and GKE specifically. Nothing in this article except for the very general idea ("setup HA for masters then upgrade one master at a time") is useful for non-Google installations.
"In this episode of Kubernetes Best Practices, let’s take a look at how Google Kubernetes Engine can make upgrading your Kubernetes cluster painless."
This is the chief complaint I have about the Kubernetes community - vendors are vying to lock up the operational complexity in their commercial solution then leave no breadcrumbs to self-implementation.
Notice that nothing in that post can be used outside of Google except for higher level order of operations.
Check out the other posts in the series[1] if you feel this one is too much like an ad and let me know what you think. Trying to keep the series a good mix of OSS and GKE specific things with the majority being OSS.

The email just said "We can hardly contain ourselves. Tune in tomorrow for a live announcement about running containers on AWS." But that almost certainly means EKS.
Any other place to view it?
Just heard that Control plane is priced at $0.20/hr, yikes... that's not bad for HA masters in every AZ, but I think it's certainly going to have a hard time competing with "you don't pay for masters at all, on GKE"
