Useful in case you need to continuously roll out updates with almost no downtime
  1. 1.
    Basically stands for copying your production container (🟦) to a new one (🟩)
  2. 2.
    Applying your changes to the new green container
  3. 3.
    Push this container to prod alongside the blue one
  4. 4.
    Perform any automated tests / QA
  5. 5.
    Gradually redirect your users to the new deployment (load balancing)
  6. 6.
    Once the transition completes, the blue container can become a backup in case you need to rollback or it can be dumped
