Load balancing is the method to seemlessly spread a service across several servers. Reliability is also improved as a faulty server can be automatically removed from the pool.
The Barracuda Load Balancer is a scalable and comprehensive solution for distributing network traffic across multiple servers. The Barracuda Load Balancer offers network administrators reliability, speed and security through session persistence with cookie data, SSL acceleration and network intrusion prevention.
Designed to help organizations achieve their availability objectives, the Barracuda Load Balancer integrates IP load balancing and network intrusion prevention into an affordable and easy to use appliance. The Barracuda Load Balancer provides comprehensive failover capabilities in case of server failure, distribution of traffic across multiple servers, and integrated protection from network intrusions.
- 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
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 facilitates automatic failover to ensure continuous availability. The Barracuda Load Balancer also assists in orchestrating scheduled maintenance windows on specific servers while maintaining application availability through other servers in the server farm.
To mitigate risks associated with failures of the load balancers themselves, two Barracuda Load Balancers can be deployed in an active/passive configuration. In the event of failure of a primary active Barracuda Load Balancer, the secondary Barracuda Load Balancer will automatically activate and assume the identity of the primary load balancer so as to maintain application availability.
