Highly demanding enterprise networks require full-featured application delivery controller that optimizes application load balancing and performance while providing protection from an ever-expanding list of intrusions and attacks. The Barracuda Load Balancer ADC is a Secure Application Delivery Controller that enables Application Availability, Acceleration and Control, while providing Application Security Capabilities.
Available in hardware, virtual and cloud instances, the Barracuda Load Balancer ADC provides advanced Layer 4 and Layer 7 load balancing with SSL Offloading and Application Acceleration. The built-in Global Server Load Balancing (GSLB) module allows you to deploy your applications across multiple geo-dispersed locations. The Application Security module ensures comprehensive web application protection, including against OWASP Top 10 and Application DDoS attacks, while monitoring outbound traffic for 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.
Barracuda Load Balancer ADC has been the preferred solution for organizations looking to load balance and secure Microsoft applications. Certified configuration and deployment guides ensure organizations can quickly and easily scale out their Microsoft applications while also securing them against targeted attacks or unauthorized access.
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, thereby optimizing application performance. Global Server Load Balancing allows redundancy across multiple sites enhancing availability, improving client response time, and speeding disaster recovery.
Application Authentication ensures that only known users are able to access critical applications. Unauthenticated traffic can be prevented from passing through the DMZ. 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 SQL injections (SQLi), Cross-site Scripting (XSS), and other OWASP Top 10 attacks.
Today, cloud computing has become a “must-have” to a majority of the enterprise IT community, for reasons ranging from economic gains to technology benefits. Intelligent traffic monitoring capabilities enable Barracuda Load Balancer ADC to distribute traffic efficiently to server resources and employs server failover for high availability. Meanwhile, Global Server Load Balancing enables redundancy across multiple sites, thereby enhancing availability and speeding disaster recovery. Barracuda ADC Load Balancer can be readily plugged into private cloud environments as well as third-party cloud platforms like Amazon Web Services.

Hundreds of thousands of organizations around the globe rely on Barracuda to deliver and protect their applications, networks, and data. The Barracuda Load Balancer ADC is part of a comprehensive line of data protection, network firewall, application delivery and security products and services designed for organizations seeking robust yet affordable protection from ever-increasing cyber threats.
SSL transactions are resource intensive and can slow down application performance. Offloading the SSL transactions to Barracuda Load Balancer ADCs frees up application server resources to focus on delivering rich applications to end users and ensure application scalability. Barracuda Load Balancer ADCs support offloading standard 1024-bit SSL keys, as well as the more secure and more process-intensive 2048-bit SSL keys.
The Load Balancer ADC can be deployed as a physical appliance or virtual appliance and can intelligently load balance hardware or virtual servers running any number of Layer 7 and Layer 4 protocols. These include HTTP/S, SMTP, IMAP, FTP/S, DNS, XML, TCP, and UDP, as well as a number of other common protocols. Additionally, it supports both IPv6 and IPv4 load balancing and can operate in full IPv6 or IPv4 networks, as well as mixed environments where an address translation is needed to bridge the IPv6 and IPv4 networks.
Intelligent traffic monitoring capabilities enable the Barracuda Load Balancer ADC to distribute traffic efficiently while ensuring high application availability. It monitors server health to determine that application servers are not only reachable, but alive. If the Barracuda Load Balancer ADC detects issues, it automatically removes downed servers from the server pool and rebalances traffic among the remaining servers. It has the ability to group servers in the application groups so that if a server in a group fails, it can automatically failover all traffic to the remaining application groups.
For scalability and high availability across data centers, Barracuda Load Balancer ADCs can be deployed to balance traffic among different sites in different geographic regions. Organizations can route traffic using a variety of methods such as primary disaster recovery (DR) or closest geographical data center.
The Barracuda Load Balancer ADC improves the user’s experience by improving server response time. Caching web content saves network bandwidth and reduces loads on backend web servers.
To maximize outbound bandwidth, the Barracuda Load Balancer ADC can automatically compress content to minimize network traffic between application servers and the end user. Best of all, this capability is compatible with most modern browsers, requiring no additional software.
The Barracuda Load Balancer ADC has full traffic control and can route requests to servers based on region, device, browser, or a number of other factors. This enables organizations to deliver customized application responses to users.
Barracuda provides a complete application delivery solution for Microsoft Exchange & Lync. Barracuda Load Balancer ADCs have been certified by Microsoft as a preferred Hardware Load Balancing solution since 2010. Our highly trained technical support engineers have worked with countless Barracuda customers and partners to design and implement robust solutions for scaling their Exchange and Lync applications.

You can find all of our technical guides and solutions at our Barracuda Campus.
Many organizations are using desktop virtualization (VDI) to securely delivery Windows and other desktop applications. Desktop infrastructure is a mission critical application that needs to scale as the organization grows. It is also important this infrastructure be resilient in the face of operational and natural disasters. The key to scalability and reliability is to load balance critical pieces of the VDI infrastructure.
The Barracuda Load Balancer ADC fully integrates Active Directory or any other RADIUS or LDAP-compatible authentication services. Combined with the strong access control capabilities, administrators can provide granular control over user/group access to resources. This ensures that only authorized users will be able to reach applications, guaranteeing that non-authenticated traffic never crosses the DMZ.
The Barracuda Load Balancer ADC provides industry-leading security to help organizations secure critical applications. It protects against OWASP Top 10 attacks such as SQL Injection, Cross-site Scripting (XSS), and Cross-site Request Forgery (CSRF). Additionally, Barracuda Load Balancer ADCs have the ability to granularly control the number of requests to protect against rate-based attacks like Denial of Service (DoS) or Distributed Denial of Service (DDoS). Administrators have the ability to intelligently fingerprint and throttle or drop traffic based on IP or client.
The Barracuda Load Balancer ADC also offers outbound content inspection for Data Loss Prevention (DLP). It prevents data leakage by either masking or blocking responses containing sensitive information such as credit card numbers or any other custom data patterns.
The security capabilities of the Barracuda Load Balancer ADC are augmented by an extensive network of more than 200,000 sensors deployed worldwide that feed into Barracuda Labs. The sensors provide valuable data for the security research team to build new security definitions and automatically update units in the field. The ability to apply new definitions and “virtually patch” ensure the highest security posture for critical applications.
Barracuda Load Balancer ADC provides full-featured application delivery along with unparalleled performance, plus greater control for applications hosted on Amazon Web Services (AWS).
