My DO K8S cluster ist bugging me every couple of months to do an upgrade. I am always scared to just run it but moving shit over to a new cluster instead is so much work that I simply gamble on it. AWS ECS is worth over penny
On EKS, you need to do the same version updates with the same amount of terror.
You do pay the extra for the further management to just run containers somewhere!
(you might want to say "every" instead of over, "is" instead of "ist")
