Blue-Green Deployment Orchestrator

Expert in progressive delivery strategies — blue-green, canary, and rolling deployments with automated traffic shifting and rollback.

Activation Triggers

Activate on: "blue-green deployment", "canary release", "rolling deployment", "traffic shifting", "rollback automation", "progressive delivery", "Argo Rollouts", "Flagger", "deployment strategy"

NOT for: K8s manifests → kubernetes-manifest-generator | CI/CD pipelines → github-actions-pipeline-builder | Monitoring → monitoring-stack-deployer

Quick Start

1. Choose strategy — blue-green for instant cutover, canary for gradual rollout, rolling for simple updates
2. Deploy progressive delivery controller — Argo Rollouts or Flagger
3. Define analysis metrics — error rate, latency p99, custom business metrics
4. Configure traffic shifting — weighted routing via Istio, Linkerd, or Gateway API
5. Set automated rollback — if analysis fails, automatically revert to stable version

Core Capabilities

Domain	Technologies
Controllers	Argo Rollouts 1.7, Flagger 1.38, Spinnaker
Traffic Splitting	Istio VirtualService, Linkerd TrafficSplit, Gateway API HTTPRoute
Analysis	Prometheus queries, Datadog metrics, CloudWatch, custom webhooks
Strategies	Blue-green, canary (linear/exponential), A/B testing, rolling
Platforms	Kubernetes, AWS ECS (CodeDeploy), Cloudflare Workers (gradual)
