The Barracuda Load Balancer is extremely easy to deploy, featuring automatic discovery and configuration too
through an intuitive Web interface. These include:
 •                                                 one-line                                            set
     Easy to set up: Barracuda Load Balancer one line configuration set up greatly simplifies service set-up. All

     that is required is the name to the service, the virtual IP on which the Barracuda Load Balan
     traffic and the Real Server IP address.
 •                                                                               Auto-Discovery.
     Automatic Discovery: All models of the Barracuda Load Balancer support Auto Discovery. This feature
     allows the Load Balancer to detect and present all reachable servers to the administrator for quick and easy
     deployment of new services
 •   Automated Service Monitoring: Barracuda Load Balancers support multiple types of server monitors. This
     enables the Barracuda Load Balancer to detect the availability of Real Servers to ensure that requests are
     sent only to healthy and active servers.
 •   Automatic Security Updates: To minimize ongoing administration associated with security, the Barracuda
     Load Balancer automatically receives current intrusion prevention and security updates from Barracuda
     Central.

Enhanced Application Delivery
Barracuda Load Balancers provide application acceleration capabilities that improve content delivery. These
include:
 •   SSL Offloading: SSL encryption / decryption are resource intensive operations that utilize significant
     amounts of processing power. The Barracuda Load Balancer can encrypt/decrypt on behalf of the Web
                               resources.
     Server, freeing up server resources
 •   Content Routing: The Barracuda Load Balancer can route traffic to different server based on incoming
     content. Routing of traffic based on content can be enforced either based on different parameters such
     header values, cookies, domain name and URL.
 •                                                                    ed
     Content Caching: The Barracuda Load Balancer provides integrated file caching for Layer 7 traffic.
     Caching stores commonly used information on the Load Balancer for quick retrieval rather than sending the
                                            s.
     request to and from the back end servers. This improves Real Server performance by reducing the amount
     server requests.
 •                                                                                me
     Traffic Compression: The Barracuda Load Balancer improves the response time for clients accessing the
     service through slow connections. The Load Balancer can compress traffic, thereby reducing the total
     amount of data sent to the client.
 •                                  nable                                                              T
     URL Rewrite: URL rewrites enable the modification of incoming and outgoing HTTP headers. This useful in
     applications that need original client IP address for logging purposes or for other operational requirements
     that require HTTP modifications.
 •   SIP Call-id persistence: Client’s connectivity to SIP servers is persisted using call id header ensuring that
     all the datagrams related to a particular call go to the same server.
 •   IPv6 support: Barracuda Load Balancer supports mixed mode of deployment for IPv6 services. Virtual IP
                                                                        addresses.

Availability & Security
Barracuda Load Balancers provide an extensive set of enterprise functionality. These include:
  •   High Availability: The Barracuda Load Balancer provides a number high availability capabilities that help
                                                                                 the
      keep mission-critical applications online. In the event of server failure, t Barracuda Load Balancer can
                                                                                    the
      detect primary failure and redirect traffic to a back up server. In addition, the Barracuda Load Balancer can
      be configured in a redundant active / passive pair for High Availability.
  •   Adaptive scheduling: The Barracuda Load Balancer offers dynamic scheduling algorithms to provide load
                              time
      balancing based on real-time server statistics. Server load distribution can be dynamically configured using
      Real Server CPU or load URL for custom load weights. For terminal session load balancing, the Load
      Balancer can use number of terminal sessions to distribute load.
  •   Global Server Load Balancing (GSLB): GSLB component resolves DNS queries allowing administrators
                                 er
      to direct traffic to a number of data center based on geographic distance, region or by priority.
  •   Server Persistence: The Barracuda Load Balancer supports Layer 4 and Layer 7 server persistence using
                             ,                headers.                                 persist
