Infrastructure as Code

All our infrastructure is managed through code, ensuring consistency, reproducibility, and version control.

Cloud Architecture​

Infrastructure Overview​

Container Orchestration​

Kubernetes Setup​

# Example deployment.yaml
apiVersion: apps/v1
kind: Deployment
metadata:
  name: api-service
spec:
  replicas: 3
  selector:
    matchLabels:
      app: api
  template:
    metadata:
      labels:
        app: api
    spec:
      containers:
        - name: api
          image: our-registry/api:latest
          ports:
            - containerPort: 8080

Resource Management​

  • CPU/Memory limits
  • Auto-scaling policies
  • Node pools configuration
  • Resource quotas

CI/CD Pipeline​

Pipeline Stages​

Deployment Strategies​

  1. Blue-Green Deployment
  2. Canary Releases
  3. Rolling Updates
  4. Feature Flags

Monitoring & Observability​

Monitoring Stack​

  • Prometheus for metrics
  • ELK Stack for logs
  • Jaeger for tracing
  • Grafana for visualization

Alert Configuration​

# Example alert rule
groups:
  - name: example
    rules:
      - alert: HighLatency
        expr: http_request_duration_seconds > 2
        for: 5m
        labels:
          severity: critical
        annotations:
          summary: High latency detected

Security​

Infrastructure Security​

  • Network policies
  • Secret management
  • RBAC configuration
  • Security groups

Compliance​

  • SOC2 requirements
  • GDPR compliance
  • Data encryption
  • Audit logging

Disaster Recovery​

Backup Strategy​

Recovery Procedures​

  1. Database restoration
  2. Service recovery
  3. Network recovery
  4. Data validation

Performance Optimization​

Infrastructure Optimization​

  • Cache strategies
  • CDN configuration
  • Database optimization
  • Load balancing

Cost Management​

  • Resource rightsizing
  • Spot instances
  • Reserved capacity
  • Cost monitoring

Environment Management​

Environment Setup​

Configuration Management​

# Example environment config
environments:
  production:
    replicas: 3
    resources:
      limits:
        cpu: 1
        memory: 2Gi
  staging:
    replicas: 1
    resources:
      limits:
        cpu: 0.5
        memory: 1Gi

Automation Scripts​

Infrastructure Automation​

#!/bin/bash
# Example infrastructure setup script
terraform init
terraform plan -out=tfplan
terraform apply tfplan

Deployment Automation​

# Example deployment script
def deploy_service(environment, version):
    update_kubernetes_config(environment)
    deploy_containers(version)
    verify_deployment()
    run_smoke_tests()

Documentation Requirements​

Infrastructure Documentation​

  • Architecture diagrams
  • Network topology
  • Security policies
  • Recovery procedures

Runbooks​

  • Deployment procedures
  • Incident response
  • Backup/restore
  • Scaling procedures
Critical Systems

Changes to production infrastructure require approval and thorough testing.
