k8s is not a pain, I would never return to something like Pupet / Ansible / etc ... to deploy bare ec2 instances, it's just re-inventing the wheel badly.

Just use ECS / Fargate with an ALB in front if you need a simpler use case.

I've had the opposite experience. I used to run k8s on bare metal, troubleshooting something at least once a month (DNS going down was a recurring favorite). The breaking point came with the churn in the ecosystem, got bitten by the deprecation of the community darling weave net cni plugin, the killing of the nginx ingress was the nail in the coffin knowing I had way too many annotation tight to the ingress that it would take longer to migrate those than go the ansible way with k8s imposing tight upgrade schedules. While I agree ansible feels a lot more dirty than k8s, I spend much less time on infrastructure, sleeping betterat night and handling things like databases is much simpler
