Decision Tree

What are you deploying?
│
├── Static site / JAMstack
│   └── Vercel, Netlify, Cloudflare Pages
│
├── Simple Node.js / Python app
│   ├── Want managed? → Railway, Render, Fly.io
│   └── Want control? → VPS + PM2/Docker
│
├── Complex application / Microservices

    └── VPS with PM2 or systemd

Platform Comparison

Platform	Best For	Trade-offs
Vercel	Next.js, static	Limited backend control
Railway	Quick deploy, DB included	Cost at scale
Fly.io	Edge, global	Learning curve
VPS + PM2	Full control	Manual management
Docker	Consistency, isolation	Complexity
Kubernetes	Scale, enterprise	Major complexity

Deployment Workflow Principles

The 5-Phase Process

1. PREPARE
   └── Tests passing? Build working? Env vars set?

2. BACKUP
   └── Current version saved? DB backup if needed?

3. DEPLOY
   └── Execute deployment with monitoring ready

4. VERIFY
   └── Health check? Logs clean? Key features work?

5. CONFIRM or ROLLBACK
   └── All good → Confirm. Issues → Rollback immediately
