Web Application Architecture The average internet user gets to see a specific page on his/her system, through a series of interaction between various components of applications, user interfaces, middleware systems, databases, server and the browser. The framework which ties up this relation and interaction together is Web Application Architecture. In a nutshell, the flow of processes typically include the user browsing for an URL, following which the browser triggers a search. Consequent to the search, the network sends data to the browser from the server, and the browser displays the page that has been requested. To put it quite simply, Web Application Architecture, includes various components and external applications. The transition to progressively better applications has resulted in transformed capabilities in frontend and backend processes. With mobile becoming the preferred device for search, the need is for Web app development and architecture that meets requirements across all platforms. Additionally, applications are becoming more complex and developers who are tasked to build an app are increasingly veering towards full stack development architecture. I. The workings of web application architecture Web Applications include two different sets of programs that run separately yet simultaneously with the shared goal of working harmoniously for delivering solutions. Typically, the two sets of programs include the code in the browser which works as per the inputs of the user and the code in the server which works as per the requests of protocols, the HTTPS. In other words, web developers need to be able to decide on the functions of the code on the server and the functions of the code on the browser and how these two will function in relation to each other.
