Application Delivery Network (Adn)

What is application delivery?

Application delivery refers to the pool of services that combine to provide application functionality, usually web-based software applications, from the data centers or cloud environments where the required data processing and computing is executed to the application clients or end-users over the internet. The services for delivering applications on a network infrastructure aim to provide a reliable user experience by providing, load balancing, security latency and TCP optimizations which combine to provide application content seamlessly. Business IT teams’ role in application delivery focuses on how applications are architected and managed within the data center, and cloud hosting services.


What is an Application Delivery Network?

Today’s networks are focused on results. It’s not enough to have active connections with no errors. Customers expect that IT management teams do their best to deliver the applications that are essential to the success of the enterprise. The goal is complete service assurance. The environment in which these efforts at faultless application delivery take place is called the Application Delivery Network (ADN).

An Application Delivery Network (ADN) is a group of services deployed simultaneously over a network to provide application availability, security, visibility and acceleration from application servers to application end users.

An application delivery network (ADN) is also a suite of technologies that, when deployed together, provide availability, security, visibility, and acceleration for Internet 

An application delivery network (ADN) provides application availability, security, visibility and acceleration. The technologies are deployed together in a combination of WAN optimization controllers (WOCs) and application delivery controllers (ADCs). The application delivery controller distributes traffic among many servers. The WAN optimization controller uses caching and compression to reduce the number of bits that flow over a network. ADNs typically assist in the acceleration of content delivery, especially immediate and dynamic content such as online gaming and trading.

How does application delivery network work?

Application delivery networks (ADN) operate with two components: a combination of a WAN optimization controller (WOC) and an application delivery controller (ADC). The ADC is positioned at the data center end of the application delivery network. … It improves application performance by focusing on latency optimization.

Application Delivery Platform Definition

An Application Delivery Platform is a suite of technologies that handles application services like load balancing, security controls and traffic management in data centers and cloud environments. The application services platform’s role is to deliver applications reliably and securely to end users.

Application delivery controller

An application delivery controller (ADC) is a computer network device in a data center often part of an application deliver network (ADN), that helps perform common tasks, such as those done by web accelerators to remove load from the web servers themselves. Many also provide load balancing ADCs are often placed in the DMZ between the outer firewall or router and a web farm.


Features commonly found in most ADCs include IP Traffic Optimization, Traffic Chaining/Steering, SSL offload, Web Application Firewall, CGNAT, DNS System, and proxy/reverse proxy to name a few. They also tend to offer more advanced features such as content redirection as well as server health monitoring.

What is ADC solution?

ADCs Act as a Reverse Proxy Client requests interact with the ADC, and the ADC, acting as a reverse proxy, interacts with application servers on the client’s behalf. Since the ADC is in the data path, application acceleration, monitoring, management and security services can be performed in-stream.


What Are the Benefits of an Application Delivery Network?

Application delivery networki offers the benefits of security visibility and acceleration:
• Moves data through the network at increased speed by using compression technologies.
• Improved network security with IP filtering, delayed binding, application firewalls and SSL encryption.
• More efficient traffic management with load balances that also provide health checks and can automatically reroute traffic when needed.
