Blue-green deployment
Blue-green deployment is a strategy where two environments, blue and green, are utilized for application deployment.
- Blue environment represents the live production environment, while green environment serves as an idle state.
- During a new deployment, traffic is switched from blue to green, allowing testing and validation.
- If the green environment performs well, the blue environment is decommissioned; otherwise, rollback is performed.
