Home Resource Center Glossary Application Delivery Controllers

Application Delivery Controllers are networking devices that reside in the data center and serve as a key part of an application delivery network. With the explosion in Internet traffic, business applications, and the number of Internet-enabled devices, application delivery controllers provide the front-end intelligence that supplements and enhances business application flows.

In addition to traditional load balancing, application delivery controllers provide a host of features that maintain the availability, speed, and security of Internet-based applications. More advanced application delivery controllers offer critical data center functions such as application acceleration, layer 4-7 load balancing, application health-checks, SSL offload, DNS application firewalls, and DDoS protection.

A10's Application Delivery Controllers, an evolution of traditional server load balancers (SLBs), ensure that customer data center applications and networks remain highly available, accelerated, and secure.

Application availability enables your Web and key infrastructure servers to scale and seamlessly redirect users in the event of an outage, using core advanced layer 4-7 load balancing and application health-checks. Acceleration capabilities provide fast and responsive service to your customers while reducing infrastructure server requirements, using features such as SSL offload, RAM caching, compression and TCP reuse. Security protection services are provided against advanced and emerging attacks for uninterrupted operations, with capabilities including Web and DNS application firewalls (WAF and DAF), application access management (AAM), SSL Insight™ and firewall load balancing (FWLB).

All A10 ADCs have advanced capabilities such as customized traffic transformation with our aFleX scripting tool, a comprehensive RESTful management API (aXAPI) enabling automated provisioning and support for multi-data center global server load balancing (GSLB).

A10 has a broad portfolio of ADCs, including our high-performance Thunder and AX Series ADCs as well as our virtual and hybrid ADCs vThunder and Thunder HVA, providing a wide choice of form factors and deployment options. Built on the Advanced Core Operating System (ACOS) with an advanced application networking feature set, A10 ADCs can achieve operational efficiency and high performance in a compact solution.
