Multilayer web application

As more complex web applications are being used today, the traditional means of deploying web applications on a single system is a story from the past. Placing all of your eggs in one basket is not a clever way to deploy a business-critical application, as it severely affects the performance, security, and availability of the application. The simple design of a single server hosting the application, as well as data, works well only for small web applications with not much traffic. The three-layer method of designing web application is the way forward.
