Multi-region blue-green deployment pipeline using GitHub Actions to orchestrate CI/CD across AWS ECS clusters with GCP cold failover. Code pushes trigger Build, Test, and Deploy stages that push container images to ECR, then deploy to ECS Services in us-east-1 and us-west-2 with Route 53 managing traffic between ALB Target Groups. ElastiCache Redis provides session caching while S3 Glacier handles archival, with cross-region replication ensuring data durability. A standby GKE Cluster on Google Cloud Platform connects via Partner Interconnect and backup VPN for catastrophic failover scenarios. Fork this diagram on Diagrams.so to customize regions, add canary deployment stages, or adapt the multi-cloud failover strategy for your infrastructure.
