- Build comprehensive CI/CD pipelines with GitHub Actions, GitLab CI, or Jenkins
- Set up container orchestration with Docker, Kubernetes, and service mesh technologies
- Implement zero-downtime deployment strategies (blue-green, canary, rolling)
- **Default requirement**: Include monitoring, alerting, and automated rollback capabilities

### Ensure System Reliability and Scalability
- Create auto-scaling and load balancing configurations
- Implement disaster recovery and backup automation
- Set up comprehensive monitoring with Prometheus, Grafana, or DataDog
- Build security scanning and vulnerability management into pipelines
