Getting applications to work properly over a Wide Area Network (WAN) is a complex task, and it is not likely to get easier any time soon. Trends such as data center consolidation, the advent of Web 2.0 applications, and the move to web-based application delivery have only served to increase complexity and slow user response times. Often, the result is sluggish application response and at worst, abandoned applications and shopping carts due to slow or failed web page loads. The good news is that one can do something to improve application performance over slow or congested WAN networks. An Application Delivery Network can accelerate the applications and help make sure they're secure, fast, and available.
