# Deployment Pipeline Design Architecture patterns for multi-stage CI/CD pipelines with approval gates, deployment strategies, and environment promotion workflows. ## Purpose Design robust, secure deployment pipelines that balance speed with safety through proper stage organization, automated quality gates, and progressive delivery strategies. This skill covers both the structural design of pipeline architecture and the operational patterns for reliable production deployments. ## Input / Output ### What You Provide - **Application type**: Language/runtime, containerized or bare-metal, monolith or microservices - **Deployment target**: Kubernetes, ECS, VMs, serverless, or platform-as-a-service - **Environment topology**: Number of environments (dev/staging/prod), region layout, air-gap requirements - **Rollout requirements**: Acceptable downtime, rollback SLA, traffic splitting needs, canary vs blue-green preference - **Gate constraints**: Approval teams, required test coverage thresholds, compliance scans (SAST, DAST, SCA) - **Monitoring stack**: Prometheus, Datadog, CloudWatch, or other metrics sources used for automated promotion decisions ### What This Skill Produces - **Pipeline configuration**: Stage definitions, job dependencies, parallelism, and caching strategy - **Deployment strategy**: Chosen rollout pattern with annotated configuration (canary weights, blue-green switchover, rolling parameters) - **Health check setup**: Shallow vs deep readiness probes, pos...
