Daily Term: Rolling Deployment

Rolling Deployment

Rolling Deployment updates servers with a new application version gradually, one or a few at a time, while keeping the system running. For example, in a 10-server cluster, a rolling deployment might update 2 servers at a time, ensuring the other 8 handle traffic. This minimizes downtime and allows monitoring during the rollout, but it can lead to version mismatches between servers during the update, requiring backward compatibility.
