Using rolling updates for Zoom Node

Admins can configure advanced rolling update options for Zoom Node deployments, including scheduling, batch sizes, and concurrency limits. They can monitor updates in real-time, view logs, and take actions like pausing, canceling, or rolling back. These features ensure efficient and flexible update management for large environments.  Services and modules can also be manually updated.
