We have a couple of dozen clusters, two per client, and can't change the architecture. We use helm and terraform and can build new clusters quickly but we can't treat them entirely like cattle because we don't own all the DNS. Our clients are not the sort to do things quickly - or even slowly.
Does anybody have any good and up to date resources comparing the current options for K8 providers? I'd like to get a feel for what it would take to switch.
