Auto-Discover
All models of the Barracuda Load Balancer support Auto-Discovery of Real Servers and Services, to
ensure quick and easy deployment of new servers. For common services, there's no need to manually
configure each port. The Barracuda Load Balancer can automatically detect which services are
running on a specified server and save deployment and configuration time.
Layer 4 IP Persistence
The Barracuda Load Balancer supports technology that directs clients back to the same server. In
environments where session persistence is required, Layer 4 IP persistence provides a fast and reliable
solution for most configurations including encrypted e-commerce traffic and database applications.
The length of time that session persistence is maintained during a time of inactivity can be enabled on
a Service level.
Layer 7 Cookie Persistence
Session persistence for many HTTP-based applications can also be tracked by using cookies. The
Barracuda Load Balancer supports all cookies that are generated or used by any application, as well
as cookie insertion for times when applications do not have or use their own cookies. Persistence in
all cases will last for as long as the cookie does unless a period of inactivity exceeds the configured
timeout value.
