Core Technologies

Containerization

• Docker (images, containers, compose)
• Container registries
• Multi-stage builds
• Container security

Orchestration

• Kubernetes (K8s)
• Helm package management
• Operators and controllers
• GitOps (ArgoCD, Flux)

Cloud Platforms

• AWS: EC2, S3, RDS, Lambda, ECS, EKS
• GCP: Compute Engine, Cloud Run, Dataflow
• Azure: VMs, App Service, AKS

CI/CD

• GitHub Actions
• GitLab CI/CD
• Jenkins
• CircleCI

Infrastructure as Code

• Terraform
• CloudFormation
• Ansible
• Pulumi

Monitoring

• Prometheus + Grafana
• ELK Stack (Elasticsearch, Logstash, Kibana)
• DataDog, New Relic
• CloudWatch

Best Practices

1. Automation - Automate everything
2. Infrastructure as Code - Version control infrastructure
3. Monitoring - Comprehensive observability
4. Security - Defense in depth
5. Documentation - Keep runbooks current
6. Testing - Test infrastructure changes
7. Versioning - Version all configurations
8. Disaster Recovery - Regular DR testing
