What are you deploying?
│
├── Static site / JAMstack
│ └── Vercel, Netlify, Cloudflare Pages
│
├── Simple web app
│ ├── Managed → Railway, Render, Fly.io
│ └── Control → VPS + PM2/Docker

├── Microservices
│ └── Container orchestration

└── Serverless
└── Edge functions, Lambda
| Platform | Deployment Method |
|---|---|
| Vercel/Netlify | Git push, auto-deploy |
| Railway/Render | Git push or CLI |
| VPS + PM2 | SSH + manual steps |
| Docker | Image push + orchestration |
| Kubernetes |
| kubectl apply |
| Category | What to Check |
|---|---|
| Code Quality | Tests passing, linting clean, reviewed |
| Build | Production build works, no warnings |
| Environment | Env vars set, secrets current |
| Safety | Backup done, rollback plan ready |
1. PREPARE
└── Verify code, build, env vars
2. BACKUP
└── Save current state before changing
3. DEPLOY
└── Execute with monitoring open
4. VERIFY
└── Health check, logs, key flows
5. CONFIRM or ROLLBACK
└── All good? Confirm. Issues? Rollback.
| Phase | Principle |
|---|---|
| Prepare | Never deploy untested code |
| Backup | Can't rollback without backup |
| Deploy | Watch it happen, don't walk away |
| Verify | Trust but verify |
| Confirm | Have rollback trigger ready |
| Check | Why |
|---|---|
| Health endpoint | Service is running |
| Error logs | No new errors |
| Key user flows | Critical features work |
| Performance | Response times acceptable |
| Symptom | Action |
|---|---|
| Service down | Rollback immediately |
| Critical errors | Rollback |
| Performance >50% degraded | Consider rollback |
| Minor issues | Fix forward if quick |
| Platform | Rollback Method |
|---|---|
| Vercel/Netlify | Redeploy previous commit |
| Railway/Render | Rollback in dashboard |
| VPS + PM2 | Restore backup, restart |
| Docker | Previous image tag |
| K8s | kubectl rollout undo |
| Strategy | How It Works |
|---|---|
| Rolling | Replace instances one by one |
| Blue-Green | Switch traffic between environments |
| Canary | Gradual traffic shift |
| Scenario | Strategy |
|---|---|
| Standard release | Rolling |
| High-risk change | Blue-green (easy rollback) |
| Need validation | Canary (test with real traffic) |
| Check | Common Issues |
|---|---|
| Logs | Errors, exceptions |
| Resources | Disk full, memory |
| Network | DNS, firewall |
| Dependencies | Database, APIs |
| ❌ Don't | ✅ Do |
|---|---|
| Deploy on Friday | Deploy early in week |
| Rush deployment | Follow the process |
| Skip staging | Always test first |
| Deploy without backup | Backup before deploy |
| Walk away after deploy | Monitor for 15+ min |
| Multiple changes at once | One change at a time |
Before deploying:
Remember: Every deployment is a risk. Minimize risk through preparation, not speed.
