Great that your setup work, i personally hate terraform and try to avoid it.

k8s is also KISS but it brings even more 'out of the box' like logging and monitoring, would highly recommend you to take a look perhaps you like it.

Terraforms state management is bad and a lot of people don't get that you store secrets in them. Bootstrapping this securly already needs infrastructure like remote stores.

Jenkins is fine i would say but with argocd you actually gain real insight. Argocd is also IaC and you can manage argocd through argocd.

The adoption of argocd in the platforms i have build, is great. Developer teams love it, get used to it very fast and don't need cluster access/ (in your case vm access).

With k8s you also get zero downtime deployment, blue / green basically for free.
