Introduction
The Barracuda Load Balancer Vx is designed to help organizations leverage their virtualized infrastructure to achieve continuous availability for their mission critical applications. The Barracuda Load Balancer Vx integrates IP load balancing and network intrusion prevention into an affordable and easy to use virtual appliance. It provides comprehensive failure detection and failover capabilities for servers, distribution of traffic across multiple servers, and integrated protection from network intrusions.
Barracuda Load Balancer Vx can be utilized by:
- Internet sites with high traffic requirements, including Web, FTP, media streaming, and content delivery networks
- Hosted applications using thin-client architectures, such as Windows Terminal Services
- Other IP services requiring optimal performance, including SMTP, DNS, RADIUS, TFTP
Technology
Barracuda Load Balancers enable you to scale up application delivery by adding additional servers to the server pool. All the incoming traffic is distributed using advanced algorithms that fully utilize all of the server capacity available for the application. The Barracuda Load Balancer’s integrated Service Monitor ensures that servers and their associated applications are operational. In the event of server or application failure, the Barracuda Load Balancer Vx facilitates automatic failover to ensure continuous availability. The Barracuda Load Balancer Vx also assists in orchestrating scheduled maintenance windows on specific servers while maintaining application availability through other servers in the server farm.
High Availability
To mitigate risks associated with failures of the load balancers themselves, two Barracuda Load Balancer Vx appliances can be deployed in an active/passive configuration. In the event of failure of a primary active Barracuda Load Balancer Vx, the secondary Barracuda Load Balancer Vx will automatically activate and assume the identity of the primary load balancer so as to maintain application availability.
Easy to use
The Barracuda Load Balancer Vx is extremely easy to deploy, featuring automatic discovery and configuration tools through an intuitive Web interface. To minimize ongoing administration associated with security, the Barracuda Load Balancer automatically receives current intrusion prevention and security updates from Barracuda Central, an advanced 24/7 security operations center that works to continuously monitor and block the latest Internet threats.
The Barracuda Load Balancer also facilitates automatic configuration through a Web-based application programming interface (API) and system monitoring through SNMP.
Affordable
With no per port or per server license fees, the Barracuda Load Balancer Vx is the most affordable enterprise-grade fully capable virtualized load balancing solution in its class.
Editions
Barracuda Load Balancer Vx is available in 2 editions with included support for up to 2 CPU cores capable of handling traffic up to 500 Mbps. The capacity and performance of the Barracuda Load Balancer Vx edition BBF 440 Vx can be easily expanded by licensing it to run on additional CPU cores on the virtual host cluster.
