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
Docker Compose. You can have multiple containers for your components (application, server, database, monitoring, analytics, etc.)
Basic ubuntu server with Apache/Nginx/Caddy.
Trafiek is also a popular choice for proxying.
DHH is pushing Kamal.
Ansible gets the job done for me.
I use it to bootstrap new servers (security, dependencies, etc) and deploy apps on them both on prem and vps. I have playbooks and roles for everything I ever needed.
I don't really like it but it's a tool that you can bend to your needs and move along.
