About Central Management

Central Management allows you to administer multiple Web Gateway appliances in your network as nodes in a
common configuration.

A configuration of multiple appliances administered through Central Management is also referred to as a
cluster.

When administering a Central Management cluster, you are dealing mainly with:

• Nodes — Appliances run as nodes that are connected to each other sending and receiving data to perform updates, backups, downloads, and other jobs.
• Node groups — Nodes are assigned to different types of node groups that allow different ways of transferring data.
• Scheduled jobs — Data can be transferred according to time schedules that you configure.
