Deployment Strategies

| Strategy | Use Case | Risk | |----------|----------|------| | Rolling | Standard updates | Low | | Blue-Green | Zero-downtime critical | Medium | | Canary | Gradual rollout | Low | | Feature Flags | A/B testing, gradual release | Low |

# Canary Example
deployment:
  strategy: canary
  steps:
    - weight: 5    # 5% traffic
      pause: { duration: 10m }
    - weight: 25
      pause: { duration: 30m }
    - weight: 100

---

Environment Matrix

| Environment | Purpose | Deployment Trigger | |-------------|---------|-------------------| | Development | Feature testing | Every commit | | Staging | Pre-production | Merged to main | | Production | Live users | Manual gate/tag |

---

Mobile Optimization

Build Optimization

| Platform | Command | Output | |----------|---------|--------| | iOS | xcodebuild -archivePath | .ipa | | Android | ./gradlew assembleRelease | .apk/.aab | | React Native | npx react-native bundle | Bundle | | Flutter | flutter build | Platform-specific |

Performance Checklist

• [ ] App size < 50MB (ideal)
• [ ] Cold start < 3s
• [ ] Memory usage monitored
• [ ] No memory leaks
• [ ] Offline capability where needed

Infrastructure as Code

Terraform Pattern

resource "aws_lambda_function" "api" {
  function_name = "my-api"
  runtime       = "nodejs18.x"
  handler       = "index.handler"
  
  environment {
    variables = {
      NODE_ENV = "production"
    }
  }
}

Docker Best Practices

# Multi-stage build
FROM node:18-alpine AS builder
WORKDIR /app
COPY package*.json ./
RUN npm ci --only=production

FROM node:18-alpine
COPY --from=builder /app/node_modules ./node_modules
COPY . .
USER node
CMD ["npm", "start"]

---

Monitoring Essentials

| Metric | Tool | Alert Threshold | |--------|------|-----------------| | Uptime | Uptime Robot | < 99.9% | | Response Time | Datadog/NewRelic | > 500ms | | Error Rate | Sentry | > 1% | | CPU/Memory | CloudWatch | > 80% |

---

Rollback Protocol

1. DETECT
   └── Alert triggers (errors > threshold)

2. ASSESS
   └── Is it deployment-related?

3. ROLLBACK
   └── Revert to last known good

4. COMMUNICATE
   └── Notify stakeholders

5. ROOT CAUSE
   └── Post-incident analysis

---

Anti-Patterns

| ❌ Don't | ✅ Do | |----------|-------| | Deploy on Friday | Deploy early week | | Skip staging | Always test in staging first | | Hardcode secrets | Use secret managers | | One big deploy | Small, frequent deploys | | No rollback plan | Always have rollback ready |

---

Handoff Protocol

When handing off to other agents:

{
  "deployment_status": "success|failed|pending",
  "environment": "staging|production",
  "version": "1.2.3",
  "rollback_available": true,
  "health_check_passed": true
}

---

When To Use This Agent

• CI/CD pipeline setup
• Deployment automation
• Mobile build optimization
• Infrastructure provisioning
• Environment configuration
• Rollback procedures

---

Remember: The goal is boring deployments. If deployments are exciting, something is wrong.
