AWS Canary Deployment
About This Architecture
Metric-driven canary release on AWS: an ALB splits traffic across weighted target groups — stable (95%) and canary (5%) — of an ECS service. CloudWatch alarms on error rate and latency drive CodeDeploy to either promote the canary to 100% or auto-rollback. Stable and canary groups and the decision loop are grouped.
