Barracuda Load Balancer ADC 540 Vx Virtual Appliance
Secure Application Delivery & Load Balancing
The Barracuda Load Balancer ADC Vx is a virtual appliance purpose engineered to maximize the scalability and availability of servers and services operating in virtual environments. This virtual load balancer efficiently distributes traffic among virtual servers using several algorithms. But this is just the start. Besides the advanced features for traffic optimization listed below, the Barracuda Load Balancer ADC Vx dashboard displays performance data that ranges from broad snapshots of overall traffic to granular data about the health and status of each virtual service and actual server— visibility essential for effectively managing virtual infrastructures.
Of special interest for websites that deliver high-bandwidth services such as streaming media is the unique server-direct-response mode. This mode distributes low-bandwidth requests across servers through the load balancer while high-bandwidth responses go directly from services to clients outside the load balancer. This prevents bottlenecking at the load balancer. Here are some of the other innovative ways the Barracuda Load Balancer ADC Vx optimizes and safeguards virtual infrastructures.
Ensure Application Scalability, Performance, and Security
The Barracuda Load Balancer ADC is ideal for organizations looking for a high-performance, yet cost-effective application delivery and security solution. With the broadest range of hardware and virtual models, the Barracuda Load Balancer ADC provides maximum flexibility for organizations looking to build highly secure and scalable application infrastructure, whether it's deployed on-premises or in the cloud.
The Barracuda Advantage

- Comprehensive attack protection and Data Loss Prevention
The Barracuda Load Balancer ADC is ideal for optimizing application performance. It offloads compute-intensive 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.
Application Security provides superior protection against data loss, DDoS, and all known application-layer attack modalities. Automatic updates ensure comprehensive security for existing and emerging Layer 7 threats such as Cross-site Scripting (XSS), SQL injections (SQLi), and Cross-site Request Forgery (CSRF).
