 What is an application delivery controller?

This whitepaper will help you understand what exactly an  application delivery controller (ADC) is and what it can do for your company. It also introduce many of the core services ADC provide and explains how they benefit both users and application administrators.

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. 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. ADCs, which are widely deployed as a key fixture in the organization, 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.

Application availability
The average consumer expects the devices and applications they interact with on a daily basis to always work, and for information to be instantly available
on demand. These expectations have carried over to the types of devices and applications that they use. To satisfy today’s workers, business applications
need to be as intuitive and easy to use as the ones they rely on for personal tasks and entertainment. Many employees are no longer restricted to using locked-down, company-owned equipment, and can use personal devices to work whenever they choose.

With people working at any time of the day or night, IT must make certain that workplace servers and applications are available around the clock. Businesses
invest heavily in IT infrastructure to ensure that employees always have access to applications and information when they are needed. Of course, servers can fail for a number of reasons ranging from mechanical problems to over-utilization and security breaches. If a server goes down, applications running on it become unusable or inaccessible.

IT organizations can plan for these occurrences by building fault tolerance into their environments. Deploying additional servers in the datacenter or at a co-located site are typical failover strategies. ADCs can help ensure high availability of applications by providing seamless failover. This is done by balancing application workloads across a cluster of active servers in one or multiple sites… Learn how you can improve the purposes, resiliency, and security with this tool.
