 Ensure Application Scalability, Performance, and Security

Barracuda Load Balancer ADC is an ideal choice for organizations that strive for high-performance, yet cost-effective application delivery and security solution. 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.

 Highly Scalable

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.

 Microsoft Certified

For organizations that look to load balance and secure Microsoft applications, Barracuda load balancer ADC is the perfect choice. The 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.

 Always Available Performance

Barracuda Load Balancer ADC distributes traffic for efficient use of server resources and employs server fail over 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.

 Secure Application Delivery

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.

 Enhance Application Performance on Public & Private Clouds

Cloud-computing has become a necessity to majority of the enterprise IT community because of its 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.





L4/L7 Load Balancing

Load Balancer ADC can be deployed as a hardware or virtual appliance and can 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 lload 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 Application Monitors

The intelligent traffic monitoring capabilities enables 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.Upon detecting any issues, it automatically removed downed servers from the server pool and re balances traffic among the remaining servers.Also, it has the ability to group servers in the application groups so that if a server in a group fails, it can automatically fail over all traffic to the remaining application groups.

Global Server Load Balancing

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.

SSL Offloading

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. It supports offloading standard 1024-bit SSL keys, as well as the more secure and more process-intensive 2048-bit SSL keys.

Authentication and Authorization

Barracuda Load Balancer ADC fully integrates Active Directory or any other RADIUS or LDAP-compatible authentication services. it is combined with the strong access control capabilities, administrators can provide granular control over user/group access to resources there by ensuring that only authorized users will be able to reach applications, guaranteeing that non-authenticated traffic never crosses the DMZ.

HTTP Caching

Barracuda Load Balancer ADC improves the user’s experience by improving server response time. Caching web content saves network bandwidth and reduces loads on back end web servers./p>

Data Compression

In order to maximize outbound bandwidth, 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.

Content Routing

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. In this way organizations can deliver customized application responses to users.

Application Attack and DDoS Protection

Barracuda Load Balancer ADC provides top-notch 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). It has 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.

Data Loss Prevention

Barracuda Load Balancer ADC 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.

Automatic Security Updates

The security capabilities of the Barracuda Load Balancer ADC are augmented by an extensive network of more than 150,000 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.

Microsoft Certified for Exchange and Lync

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.

Pre-Built Templates for Exchange, SharePoint, Lync, and more

For high availability, performance and security ,thousands of organizations from numerous verticals deploy Barracuda. There exists a number of certified deployments and solution guides for all commonly deployed models and versions of Exchange, SharePoint, Lync, Terminal Services, IIS, Threat Management Gateway (TMG) and other popular Microsoft applications.

Cloud Edition for Amazon Web Services

Barracuda Load Balancer ADC provides full-featured application delivery along with unparalleled performance, plus greater control for applications hosted on Amazon Web Services (AWS). It integrates with CloudFormation Templates to support fully automated deployments with bootstrapping and High Availability (HA).


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 flexible in the face of operational and natural disasters. The key to scalability and reliability is to load balance critical pieces of the VDI infrastructure.
