I was shocked to see how much more the extended support (per hour) cost is for Kubernetes on AWS.
Haven't had that situation myself on AWS yet, but ran into it a few times on Azure
I can't remember to have paid extra on Azure though, but maybe we did. Certainly not 6x the price though.
PS: not sure why it got flagged the first time, but I think because I used a different title. Sorry.
