Ask HN: What are the production level hosting solutions for on prem

I am a software developer mainly have experience with kubernetes. Kubernetes is great, but we all know it is too much for a simple hosting solution. So what are the other hosting solutions, like something as web server, something to route traffic, ingress, proxy etc you use at production level for self hosted, or on prem deployments. Idealy something that can give flexibility, easy start and simplicity
