Application Delivery Network Basics
Global businesses increasingly use remote desktops, cloud-based services, and distributed WANs. However, as distances increase, performance lags. Users across an Nangs ocean may not experience the same speedy response as their colleagues located elsewhere. One way to improve the user experience is to use an application delivery network.
What is an Application Delivery Network?
An application delivery network is a special, private network built to improve and accelerate the availability, visibility, and security of applications across the network. This system consist of globally distributed “points of presence” (POPs) which ensure that a delivery point is close to globally distributed users no matter where in the world they may be.
Application delivery networks use a variety of techniques to optimize the network for performance. For example, TCP optimization, caching and compression, bandwidth scaling, and data deduplication are common optimization tasks used to accelerate application delivery.
Not only is the entire application network optimized to ensure accelerated, reliable application delivery, it is monitored in real-time to identify and resolve congestion, connectivity, and capacity issues. Preventative security measures are also implemented across the global network to combat security threats.
This technology is similar to content delivery networks. Content delivery networks consist of data centers located around the world. Local copies of content are stored on these global servers, ensuring that nearby users have a faster means of receiving the content that they want to consume. Content delivery networks work well for serving static content such as webpages, music downloads, and photos. However, they’re not as well suited for delivering content that changes frequently such as interactive content associated with Web applications. As Web applications have proliferated, this system have evolved to handle the demand for improved application performance.
The Benefits of Using an Application Delivery Network
Improved application performance is perhaps the biggest benefit of using this technology. That in turn delivers other important benefits:
- Improved employee morale– If your employees must wait a seemingly endless amount of time to log into their remote desktops or use a Web app, there’s bound to be a lot of grumbling. By using an optimized this technology, you can improve application performance and employee morale at the same time.
