L4/L7 load balancing
The Load Balancer ADC can be deployed as a hardware 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 application monitors
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.
Global server load balancing
For scalability and high availability across data centers, Barracuda Load Balancer ADC 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 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.
Authentication and authorization
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 improves the user's experience by increasing 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.
Application attack and DDoS protection
The Barracuda Load Balancer ADC provides industry-leading security to help organizations secure critical applications. 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.
Data loss prevention
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.
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.
