The document discusses how to deploy Mule ESB applications using the Mule Management Console (MMC). MMC provides a centralized interface to monitor, manage, and administer Mule ESB instances. To deploy an application, users log into MMC and use the Deployments tab to provision applications by deploying, undeploying, or redeploying them to target Mule ESB servers. The Deployments tab displays all provisioned applications and their statuses. Users can create new deployment groups by specifying applications, servers, and server groups for the group.
