DNS + CDN + serverless + container PaaS deployment patterns. Choose by workload: **Cloudflare** (DNS+CDN+WAF+Workers+Pages+R2+D1+Zero-Trust; default for edge), **Vercel** (Next.js + frontend), **Railway** (monorepo + DB-included), **Fly.io** (global edge + Fly Machines), **Render** (low-config containerized). Skip when K8s is the right tool.
