[Trained model]
   │
   ├─ 1) INFER: CHOOSE DEPLOYMENT
   │     Online? Offline?
   │     Real-time(low-latency) / Serverless / Async / Batch
   │
   ├─ 2) DEPLOY SAFELY
   │     Shadow (zero-risk), Canary (gradual), Blue/Green (flip)
   │
   ├─ 3) MONITOR
   │     Data drift (no labels) vs Model Quality (labels delayed)
   │     CloudWatch (metrics), Model Monitor (distribution)
   │
   ├─ 4) OPTIMIZE
   │     Cost: Spot(learn), Serverless(inference), MME
   │     Speed: Neo, Inferentia, Elastic Inference
   │
   ├─ 5) INCIDENT RESPONSE
   │     Degradation → alarm → retrain (auto or manual)
