Using a rolling deployment approach replaces older replicas with newer versions in a staggered manner, which helps limit downtime and keeps service disruptions minimal. Initiating ephemeral pods that wait for an entire cluster rebuild prolongs service interruption. Freezing all services before applying changes imposes a full outage period. Pushing updates all at once with forced rollout tends to create noticeable downtime for users.
