Blue/Green Deployment

Understands the fundamentals of Blue/Green Deployment. Applies basic practices in daily work. Follows recommendations from the team and documentation.

Understands blue-green deployment concept: two identical environments, traffic switching. Knows advantages (zero-downtime, fast rollback) and limitations (resources, DB migrations). Observes the deployment process under senior engineer guidance.

Studies blue-green deployment concept: two identical environments, instant traffic switching. Configures blue-green through AWS ALB target groups. Understands benefits: zero downtime, instant rollback. Practices switching between blue and green environments in staging.

Independently creates and maintains Blue/Green Deployment. Configures CI/CD pipelines. Automates routine operations.

Implements blue-green deployments in Kubernetes: through Service selector switch, Argo Rollouts or Istio traffic management. Configures automated post-switch health verification, rollback scripts. Manages database migrations for both-version compatibility.

Implements blue-green deployment in Kubernetes with ArgoCD Rollouts. Configures health checks and automated rollback on metric degradation. Introduces database migration strategy for both-version compatibility. Automates smoke tests during switching. Configures monitoring of both environments for comparison.

Designs CI/CD architecture with Blue/Green Deployment. Optimizes pipeline speed and reliability. Introduces progressive delivery.

Designs blue-green strategy for production: automated switching with pre/post-deployment hooks, monitoring integration for automatic rollback. Solves database migration, session management and cache invalidation challenges during switching.

Designs blue-green deployment strategy for multi-service architecture. Solves challenges: database schema compatibility, session management, cache warming. Introduces automated traffic shifting with rollback triggers based on SLOs. Develops runbooks for complex deployments with inter-service dependencies.

Defines DevOps strategy with Blue/Green Deployment. Establishes CI/CD standards. Introduces platform engineering approaches.

Defines blue-green deployment standards for the organization: when to apply blue-green vs canary vs rolling, validation checklists. Designs universal deployment pipeline with strategy selection, automated verification and SLO-based promotion.

Defines zero-downtime deployment strategy for the organization. Manages deployment platform supporting blue-green, canary and rolling updates. Builds deployment safety metrics: change failure rate, rollback frequency, MTTR. Introduces deployment windows and change management for regulated environments.

Shapes blue-green deployment strategy for cloud infrastructure: Route 53 weighted routing, ALB target group switching, ECS blue-green through CodeDeploy. Designs rollback automation, database migration strategy and smoke testing for zero-downtime infrastructure updates.

Develops zero-downtime deployment strategy for all infrastructure: standards for each service type (stateless, stateful, data pipeline). Defines deployment platform architecture with SLO-driven automatic strategy selection and rollback.

Architecturally defines enterprise deployment strategy. Designs multi-regional blue-green deployment for mission-critical systems. Defines deployment safety standards for dozens of teams. Develops deployment practices maturity assessment framework. Influences organizational SRE culture.
