High Availability Deployment
The High Availability deployment is configured in two separate networks and these networks are then
clustered to interact with one another. You can combine the Barracuda Spam Firewall appliance with
other nodes and appliances into a cluster. One node within the cluster functions as the master node,
and the others act as slaves. You can access and configure all nodes in the cluster from the same Web
GUI. You can configure cluster parameters on the master node, which then propagate to the slave
nodes.The Barracuda Spam Firewall scans the HTTP traffic for spam and viruses; it also provides
content filtering.
Figure 2.3 illustrates a basic installation using the High Availability Deployment..
