A Local Distributor is a proxy that optimizes the distribution and management of Remote Agents. Data centers can use Local Distributors to do the following:
Minimize network traffic during deployments. The Master Server sends one copy of a component to a Local Distributor, which replicates the component for installation on other servers.
Minimize firewall reconfigurations. If a firewall stands between the Master Server and a collection of servers, administrators can open the firewall only for the Local Distributors, rather than for every server involved in a deployment.
Minimize the load to the Master Server during large scale deployments.
