The Barracuda Web Security Gateway lets organizations benefit from online applications and tools without exposure to web-borne malware and viruses, lost user productivity, and misused bandwidth. As a comprehensive solution for web security and management, it unites award-winning spyware, malware, and virus protection with a powerful policy and reporting engine.
Due to an increasing number of users needing to access the web, organizations seek to augment their Barracuda Web Security Gateway deployments by clustering additional devices to their existing deployment. In such growing deployments, there may be a mix of Barracuda Web Security Gateway hardware models — from the lower end devices that the organization started with, to newer, more capable Web Security Gateway devices that can handle higher traffic loads. The issue with such clustering is in the distribution of the web traffic load across the various Web Security Gateways. A router would typically distribute all the web traffic evenly across all the devices, without considering the capability of the devices. This can lead to performance issues.
The Barracuda Application Delivery Controller
The Barracuda Load Balancer ADC enables organizations to add scalability, redundancy, and security to applications in their data centers with a single, integrated and cost-effective platform. When used with the Barracuda Web Security Gateway, it provides performanceaware load balancing and redundancy. This ensures higher performance from the Barracuda Web Security Gateway cluster — all without breaking the IT budget.
The Load Balancer ADC is deployed in between the clients of the Web Security Gateway cluster and distributes traffic across the various devices in the cluster. Using its built-in load-balancing algorithms, the ADC will perform performance-aware traffic distribution across the devices in this cluster. The Barracuda Load Balancer ADC queries each of the connected Barracuda Web Security Gateway devices in the cluster for performance and load information. The load-balancing algorithm will then send traffic to the devices with lesser load, improving the efficiency of the Barracuda Web Security Gateway.
By ensuring that the Web Security Gateway cluster is performing at its best, the Barracuda Load Balancer ADC enables faster Internet access through the cluster. In case one of the nodes in the Barracuda Web Security Gateway Cluster fails, the Barracuda Load Balancer ADC will remove this device from the load balancing scheme and direct traffic across other devices. Configuration of the Barracuda Web Security Gateway devices in a cluster is simple. Administrators can easily configure all devices in the cluster by using the link management configuration and synchronize the configuration across all the devices in the cluster.
