I strongly disagree. I've built a couple in house PaaS type systems in the past with various degrees of success on more classical tech like straight up EC2 using a variety of Terraform/Ansible/CloudFormation/Scripting but the dev experience has always been painful compared to Kubernetes.
Developers really love working with Kubernetes. It doesn't take a lot to get started and if you're not doing anything too crazy it is a huge productivity boon IMO.
Where things get hairy is persistence, but that's the case regardless of Kubernetes or not.
Ah yes, you're right. I am sure you have a much better understanding of the requirements each of these build outs sitting behind your keyboard over there.
