Figure 1. System Resources

A VCLGroup contains one or more deployments, domains and VCL files. A deployment contain one or more tags. And an agent is tagged with one or more tags. The VCLGroup is then deployed (based on tags) to one or more agents.

A router can also have tags and be used for tagged based routing. A RoutingRule is an optional addition to a VCLGroup. Applied only if the VCLGroup should be used with traffic routing.
