Answer Description

The Blue/Green deployment strategy allows a new version of the application to be deployed alongside the old version before a full-scale switch. This method minimizes downtime and provides an immediate rollback mechanism if the new version fails, by simply routing traffic back to the old environment. Incremental deployments, such as Rolling and Rolling with additional batch, would still have a limited impact on availability as instances are updated in batches and do not provide an immediate rollback capability. Immutable deployments, while minimizing downtime by provisioning new instances, do not provide the immediate rollback capability that Blue/Green deployments offer.
