If I remember right (and this is going back a few years to when Sean first wrote that post), the rolling-updates feature never made it out of alpha status on GCE. I had to apply for an allowlist on my account to enable it (or a closely related feature) when I was experimenting with it. I’ve not tried it recently, but GCE instance-groups are probably the mechanism by which you activate zero-downtime upgrades now. Anil
