Highly demanding enterprise networks require full-featured application delivery that optimizes application load balancing and performance on Amazon Web Services.

The Barracuda Advantage

  • Proven technology that has blocked more than 11 billion real-world attacks
  • High-performance platform designed for data centers
  • GeoIP-based application control
  • Pre-built application templates for rapid deployment
  • Available as a virtual appliance

Product Spotlight

  • Multiport platform with fiber and copper network interfaces
  • Advanced Layer 4 & Layer 7 load balancing
  • SSL offloading & application acceleration
  • Global Server Load Balancing for application delivery across data centers
  • Comprehensive attack protection and Data Loss Prevention


The Barracuda Load Balancer ADC is ideal for optimizing application performance. It offloads computeintensive SSL transactions from the server, preserving resources for applications. In addition, optimization features such as caching, compression, and TCP pooling enable faster application delivery and ensure scalability.


Using health and performance checks, the Barracuda Load Balancer ADC distributes traffic for efficient use of server resources and employs server failover for high availability. Global Server Load Balancing allows redundancy across multiple sites enhancing availability and speeding disaster recovery.


Content routing and content rewrites enable full control of application traffic and customized application delivery based on users, regions, and/or devices. Client controls gives administrators the ability to throttle requests to ensure application availability even during periods of heavy traffic.

"Barracuda has simplified everything. We set up two appliances within four hours, and the solution works great—for a fraction of what our previous solution cost."
