Hosting options and how to choose

Learn the ladder from simplest to most control: (1) demo hosts — Hugging Face Spaces, Streamlit Community Cloud (free, for demos); (2) platforms (PaaS) — Render, Railway, Replit (push code or a container, they run it); (3) serverless containers — Google Cloud Run, AWS App Runner, Azure Container Apps (pay per use, scale to zero); (4) virtual machines (full control, you manage everything); (5) Kubernetes (many services, big scale, needs a team). Choose by: users and traffic, need for GPUs, budget, data rules, team skills.
