Ops is a skill just like SQL/Backend/Frontend is. Most Devs here would recoil at thought of me writing Frontend with some LLM that swore up and down it would protect me from common SPA JS bugs/footguns I run into. I recoil at thought of vibing your way through Terraform/OpenTofu against Cloud Resources you don't understand and is loaded with footguns. Also Terraform/OpenTofu is riddled with footguns by itself. The fact 4 examples on their website is Kubernetes/Kubernetes/VM/Cloud Run is scary. If you need LLM to run Kubernetes, you shouldn't be running it. Cert Manager, External DNS and other things are complete grues that will eat you.
What would I recommend, something that takes a container you create and runs it for you. GCP Cloud Run/Azure Web App/AWS Something/Heroku/Fly.io. (I work with GCP/Azure) Database should be Cloud Managed. If that's outside budget, then cheap VPS from company like Vultr/DigitalOcean with Docker Compose is my recommendation. Simple, easy to understand and easy to write simple GitHub action for. Once you need scaling, you can hire an Ops person and they can wrangle Terraform/Kubernetes.
