Creating Services
A Service is a combination of a Virtual IP (VIP), and one or more TCP/UDP ports that the Service
listens on. Traffic arriving over the designated port(s) to the specified VIP is directed to one of the
Real Servers that are associated with a particular Service. The Barracuda Load Balancer determines
the order in which the traffic is distributed to the Real Servers based on the policy type for the Service.
To create a load-balanced Service, see Creating a Service on page 44.
