Virtual appliance provides load balancing, high availability and application acceleration with intrusion prevention
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
High Availability and Scalability
The Barracuda Load Balancer Vx was designed to provide high availability and scalability by intelligently distributing traffic across multiple servers using several scheduling algorithms and persistence mechanisms. It performs intelligent network and application-layer server health checks to ensure the most efficient load distribution and resource utilization. The ability to transparently add or remove servers on the fly increases application uptimeswhile providing a smooth end user experience. For additional availability it can be deployed in an active/passive configuration wherein a hot standby immediately takes over services if the master unit fails.
Application Acceleration
Features such as content caching, data compression and connection pooling improve application response times and reduce network congestion. These features also lessen connection-management overhead from the servers. Content rules provide application-aware traffic distribution by redirecting requests to the subgroup of servers which can process the requests most efficiently. This allows architecting a highly scalable application-delivery network with optimal resource utilization. SSL offloading further reduces server load and consolidates certificate management.
Security
An integrated intrusion prevention system deep scans all incoming data, including SSL encrypted data, to filter malicious data before it reaches your servers. Web application data can be selectively inspected and modified for added protection. Automated IPS definition updates ensure immediate
protection from the latest attacks.
Affordable and Easy to use
With advanced load balancing backed by industry-leading customer support, the Barracuda Load Balancer Vx provides unmatched value. The intuitive web UI streamlines deployment and configuration. Multiple deployment options allow quick, seamless integration into any network topology. With features like automated discovery, it only takes a few minutes to set up server load balancing.
