What is an Application Delivery Controller?

Application Delivery Controllers also known as ADCs, gaining traction within the last decade, largely due to increased demand for legacy load balancing appliances to handle more advanced application delivery requirements and improve application performance. Application delivery controllers (ADCs) are purpose-built networking appliances whose function is to improve the performance, security, and resiliency of Application Delivery over the web.

Application Delivery

Applications have evolved significantly over the years. The term delivery is now generally accepted as the means of bringing an application to the user in this new era of mobility and cloud. In the enterprise, business applications have moved away from desktop-bound software installed on a local server accessed by users across the LAN. Modern applications need to work across all types of networks, and at locations beyond the confines of the physical workplace.

Application delivery controllers, which are widely deployed as a key fixture in the enterprise, help applications adapt to the networks and protocols that are in place today. They also ensure that applications perform optimally, are always available and don’t present any security risks either to the user or business.

App Architecture

Application delivery is more than just enabling access to an application.  App architectures can be deployed in a manner that inherently increases overall security posture and accommodates very rapid delivery of new apps and functionalities without compromising compliance, i.e. The LKMethod™ Reference Architecture.
