+- **Test green**: Perform testing and validation in the green environment to ensure the new version works as expected.
 - **Switch Traffic**: Once the green environment is verified, switch the production traffic from blue to green. Optionally, the traffic switch can be done gradually to avoid potential problems from affecting all users immediately.
 - **Monitor**: Monitor the green environment to ensure it operates correctly with live traffic. Take your time, and make sure you’ve monitored every single major event before issuing the “green light”.
 - **Fallback Plan**: Keep the blue environment intact as a fallback. If any issues arise in the green environment, you can quickly switch traffic back to the blue environment. This is one of the fastest rollbacks you’ll experience in deployment and release management.

 A container is a runtime instance of a container image (which is a lightweight, executable package that includes everything needed to run your code). It is the execution environment that runs the application or service defined by the container image.
 
 When a container is started, it becomes an isolated process on the host machine with its own filesystem, network interfaces, and other resources.

 A virtual machine (VM), on the other hand, is an emulation of a physical computer. Each VM runs a full operating system and has virtualized hardware, which makes them more resource-intensive and slower to start compared to containers.
