# Compute Layer: AWS ECS/Lambda or Azure App Service (application logic)
# Data Layer: AWS RDS or Azure SQL (persistent storage)
# CDN/Storage: Cloudflare R2 or AWS S3 (static assets)

Benefits:
- Best-of-breed services per layer
- Geographic redundancy
- Cost optimization across providers
```

### AWS ECS Deployment with CI/CD

```yaml
# GitHub Actions workflow
name: Deploy to ECS
on: push
jobs:
  deploy:
    - Build Docker image
    - Push to ECR
    - Update ECS task definition
    - Deploy to ECS service
    - Wait for deployment stabilization
```

### Kubernetes GitOps with ArgoCD

```yaml
# Git repository structure
/apps
  /production
    - deployment.yaml
    - service.yaml
    - ingress.yaml
  /staging
    - deployment.yaml

# ArgoCD syncs cluster state from Git
# Changes: Git commit → ArgoCD detects → Auto-sync to cluster
```

### Multi-Stage Docker Build

```dockerfile
# Build stage
FROM node:20-alpine AS build
WORKDIR /app
COPY package*.json ./
RUN npm ci
COPY . .
RUN npm run build

# Production stage
FROM node:20-alpine
WORKDIR /app
COPY --from=build /app/dist ./dist
COPY --from=build /app/node_modules ./node_modules
USER node
CMD ["node", "dist/server.js"]
```

### FinOps Cost Optimization Workflow

```yaml
# 1. Discovery: Identify untagged resources
# 2. Analysis: Right-size instances (CPU/memory utilization)
# 3. Optimization:
#    - Convert to reserved instances (predictable workloads)
#    - Use spot instances (fault-tolerant workloads)
#    - Schedule start/stop (dev environments)
# 4. Monitoring: Set budget alerts, track savings
# 5. Governance: Enforce tagging policies
```

### DevSecOps Security Pipeline

```yaml
# 1. Code Commit
# 2. SAST Scan: SonarQube, Semgrep (static code analysis)
# 3. Dependency Check: Snyk, Trivy (vulnerability scanning)
# 4. Build: Docker image
# 5. Container Scan: Trivy, Grype (image vulnerabilities)
# 6. DAST Scan: OWASP ZAP (runtime security testing)
# 7. Deploy: Only if all scans pass
# 8. Runtime Protection: Falco, AWS GuardDuty
```

### Terraform Infrastructure Deployment

```hcl
# 1. Write: Define infrastructure in .tf files
# 2. Init: terraform init (download providers)
# 3. Plan: terraform plan (preview changes)
# 4. Apply: terraform apply (create/update resources)
# 5. State: Store state in S3 with DynamoDB locking
# 6. Modules: Reuse common patterns across environments
```

## Best Practices

### DevOps
- **CI/CD**: Automate testing and deployment, use feature flags for progressive rollouts
- **GitOps**: Declarative infrastructure, Git as single source of truth, automated sync
- **Monitoring**: Implement observability (logs, metrics, traces), set up alerting
- **Incident Management**: Runbooks, postmortems, blameless culture
- **Automation**: Infrastructure as code, configuration management, self-service platforms

### Security (DevSecOps)
- **Shift Left**: Security scanning early in pipeline (SAST, dependency checks)
- **Secrets Management**: Use Vault, AWS Secrets Manager, or sealed secrets (never in code/Git)
- **Container Security**: Run as non-root, minimal base images, regular scanning
- **Network Security**: Zero-trust architecture, service mesh, network policies
- **Access Control**: Least privilege IAM, MFA, temporary credentials
- **Compliance**: Audit logging, encryption at rest/transit, regular security reviews
- **Runtime Protection**: Security monitoring, intrusion detection, automated response

### Cost Optimization (FinOps)
- **Tagging**: Enforce resource tagging for cost allocation and tracking
- **Rightsizing**: Analyze utilization, downsize over-provisioned resources
- **Reserved Capacity**: Purchase RI/savings plans for predictable workloads (up to 72% discount)
- **Spot/Preemptible**: Use for fault-tolerant workloads (up to 90% discount)
- **Scheduling**: Auto-stop dev/test environments during off-hours
- **Storage Optimization**: Lifecycle policies, archive to cheaper tiers, delete orphaned resources
- **Monitoring**: Budget alerts, cost anomaly detection, chargeback/showback
- **Governance**: Approval workflows for expensive resources, quota management

### Kubernetes
- **Resource Management**: Set requests/limits, use horizontal pod autoscaling
- **High Availability**: Multi-zone clusters, pod disruption budgets, anti-affinity rules
- **Security**: RBAC, pod security policies, network policies, admission controllers
- **Observability**: Prometheus metrics, distributed tracing, centralized logging
- **GitOps**: ArgoCD/Flux for declarative deployments, automatic drift correction

### Performance
- **Compute**: Auto-scaling, load balancing, multi-region for low latency
- **Caching**: CDN, in-memory caching (Redis/Memcached), edge computing
- **Storage**: Choose appropriate tier (SSD vs HDD), enable caching, CDN for static assets
- **Containers**: Multi-stage builds, minimal images, layer caching
- **Databases**: Connection pooling, read replicas, query optimization, indexing

### Development
- **Local Development**: Docker Compose for consistent environments, dev containers
- **Testing**: Unit, integration, end-to-end tests in CI/CD pipeline
- **Infrastructure as Code**: Terraform/CloudFormation for repeatability
- **Documentation**: Architecture diagrams, runbooks, API documentation
- **Version Control**: Git for code and infrastructure, semantic versioning
