Blue-Green Deployment Rollback Time Calculator

Calculate blue-green deployment rollback time: Rollback = time to switch load balancer from green to blue environment. With DNS routing: 0-60s (instant switch, TTL-dependent). With sticky sessions: drain time + switch.

How It Works

Calculate blue-green deployment rollback time: Rollback = time to switch load balancer from green to blue environment. With DNS routing: 0-60s (instant switch, TTL-dependent). With sticky sessions: drain time + switch

Each component has a specific meaning:

  • Green — The green recorded for the scenario being assessed.

Note: Interpret the blue-green rollback time result against the thresholds and context described above.

How to Use

Enter the green for the scenario you are assessing. Calculate blue-green deployment rollback time: Rollback = time to switch load balancer from green to blue environment. With DNS routing: 0-60s (instant switch, TTL-dependent). With sticky sessions: drain time + switch. Use the blue-green rollback time result to inform your calculation.
