Application Delivery Controllers (ADC) are networking devices normally deployed in datacenters as part of an application delivery network (AND). Today, due to exponential growth in Internet traffic contributed by cloud-based business applications and services, application delivery controllers are deployed to perform load balancing, DMZ buffering and application flow optimization.
In addition to load balancing, which is widely perceived as the main feature of ADC, there are other common features found in today’s application delivery controllers with various OSI layer 3-7 services including SSL offload, web application firewall, DNS application, proxy configurations and DDoS protections.
Recommended Lanner Network Appliances for Application Delivery
Lanner supplies powerful network appliances, on which several applications such as an application delivery controller, carrier deployment of IPv6 migration/transition and cloud deployment could be built. Lanner’s appliance can not only support multi-tenancy for deployment at data centers, but also a large number of sessions with a fast transaction rate. It had to have competitive advantage in both performance and power/cost efficiency.
