Immutable environment updates are an alternative to rolling updates. Immutable environment updates ensure that configuration changes that require replacing instances are applied efficiently and safely. If an immutable environment update fails, the rollback process requires only terminating an Auto Scaling group. A failed rolling update, on the other hand, requires performing an additional rolling update to roll back the changes.

Selected Answer: D
D immutable. In immutable deployment, you create new instances and deploy the new version there. In the meantime you keep the instances where you have the old version. If a problem occurs with the new version, you can always go back to using the instances that have the old version. Once and only after you make sure that the new version works as expected, you delete the instances that have the old version.
