Prompt
Our core order processing system stores session state and pending queue items directly on local disk instances. We plan to switch 100% of traffic from blue to green instantly. What critical data management requirement must be addressed before executing this switch?

What's inside
The instructions your model reads when the skill loads.
Enterprise-grade automation solution for deployment strategy operations across AWS, Azure, GCP, and on-premise environments to maximize operational efficiency while maintaining security and compliance standards.
When to Use
Production Releases: When deploying to production and need zero-downtime or safe rollback capabilities
High-Risk Changes: For database migrations, API breaking changes, or infrastructure updates
Multi-Environment Deployments: When coordinating deployments across dev, staging, and production
A/B Testing: When gradually releasing features to subsets of users
Emergency Rollbacks: When you need quick rollback capabilities for failed deployments
Blue-Green Switches: For instant traffic switching between identical environments
Canary Analysis: When testing new versions with small traffic percentages before full rollout
Gotchas
Common Pitfalls
Database Migrations: Never run database migrations in canary deployments - they affect all traffic
Stateful Applications: Blue-green deployments don't work well with stateful applications without data synchronization
Traffic Routing: Ensure load balancers properly route traffic and don't cache old endpoints
Health Check Timing: Health checks must be long enough to allow applications to start properly
Edge Cases
Resource Limits: Canary deployments temporarily double resource requirements during overlap periods
Session Affinity: Applications with session affinity may have issues during traffic shifting
External Dependencies: Third-party APIs may have rate limits that get exceeded during deployments
Cross-Region Deployments: Global applications need careful coordination to avoid region-specific issues
Performance Issues
Rollback Time: Blue-green deployments allow instant rollback, but rolling updates can take 10+ minutes to rollback
Health Check Delays: Applications with slow startup times (Java, .NET) need longer health check intervals
Traffic Shifting: Gradual traffic shifts in canary deployments can cause inconsistent user experiences
Resource Cleanup: Old deployment versions may not be cleaned up automatically, causing resource waste
Security Considerations
Secret Rotation: New deployments may need access to updated secrets or certificates
Network Policies: New pods may be blocked by existing network policies during deployment
API Keys: Ensure new deployments have proper API key access and don't use expired credentials
Compliance Logging: Maintain audit trails during deployments for compliance requirements
