Description of "Figure 2-4 Oracle Traffic Director"

The Blue-Green deployment process uses two identical environments-Blue and Green. Only one environment is active, serving all the traffic with the load balancer, and the other is in standby mode.

Once the traffic is diverted to the Blue environment using the Load balancer, health checks are performed for all the currently active Blue environment components with traffic.

For example, consider that Blue is on standby and Green is active. Then, when the updates are completed in the Blue environment, you can use the load balancer to switch the traffic to the Blue environment.
