Cumberland Hotels SaaS multi-environment CI/CD pipeline orchestrates code from GitHub through five automated stages—source, build, test, artifact, and deploy—using GitHub Actions, AWS CodePipeline, and CodeDeploy across Dev, QA, UAT, and Prod accounts. Docker images are built via CodeBuild, scanned with SAST/DAST, stored in ECR, and promoted through approval gates before deployment to ECS, Lambda, and RDS across isolated VPCs. Infrastructure as Code via Terraform and configuration management with Ansible ensure consistent, repeatable deployments while CloudWatch, SNS alerts, and rollback paths provide observability and failure recovery. This architecture demonstrates enterprise-grade separation of concerns, least-privilege IAM roles, and multi-account isolation for SaaS workloads. Fork this diagram on Diagrams.so to customize for your own multi-tenant or multi-environment deployments, adjust approval gates, or integrate additional security scanning tools.
