Online is the New Cool: Your Simple Guide To Web Application Architecture

posted by Chris Valentine

The advent of elaborate Web Application Architecture has come with a host of user benefits in its wake. This has significantly enhanced the User Experience (UX) while also improving on the User Interface (UI).

With the basic building blocks of a web application being in its architecture, this is your simple guide to web application architecture.

What is Web Application Architecture?

Simply put, Web Application Architecture is the whole system of coordinated interactions. These are the interactions between the various components of the web application which include the browser, the server and database. Web application architecture also includes the sub-components and the entire external application interactions over a network.

In a nutshell, the Web application architecture could be defined with this easy flow that is all so common today.

  • The user opens a Browser and types a given Uniform Resource Locator (URL) and taps “search.”
  • The browser locates and requests the specific URL, over a network.
  • The server responds to this request by sending over the requested files to the browser.
  • The browser displays the request web information in simple and understandable form. The user can therefore interact with the page.

The web application architecture involves the use of codes by the interacting components and sub-components of the app. These codes are responsible for relaying relevant requested information. Users may not even have to know exactly what they are searching. Being the top read that the web app architecture is this year, it’s only fair that we see how it works.

Web application architecture is so critical in this age and era because every other application communicates via the web. It is, therefore, just as important because it includes the broad spectrum of efficiency, scalability, internet security and functionality.

How does web application architecture work?

Web application architecture is designed in two sides. These are the front-end and the back-end sides. Alternatively, you could call these sides the client side and the server side respectively. While the client is the web browser that seeks information online, the server hosts the entire website.

The client side

The client side often uses JavaScript because it scripts on the browser once you load a webpage. However, it also uses basic HTML and CSS codes. Because these languages need no Operating System adaptation, the browser is able to manage how users interact with the page.

The server side

Likewise, server side ordinarily runs its Scripts before the HTML from the browser is loaded. The server side could use Hypertext Preprocessor (PHP), Ruby on Rails or even ASP.NET, Python, among other server-based programming languages. The truth is that just any programming language that can respond by relaying data requested by the browser could be used on a server.

Web Application Architecture and the future

Web application architecture is absolutely important to the future trends. This is because it defines the interactions between applications, users and servers. It brings the whole spectrum of the front-end, the network, security, servers, databases and app marketing into perspective.

The organizational design of web app architecture will largely inform the way applications perform. These may range from how they relay HTTP data that both the client and server can relate to. The other features of modern web application architecture are its ability to grant users certain permissions to access restricted content.

Information security also happens to be a major concern going into the future. Web app architecture also contains critical security features to monitor keep malice out if bay. It also offers authentication to users and ensures all requests made have the right data.


Web application architecture involves the interaction between the user and the server databases via a network. The client side can exclusively perform certain functions. The same is true for the server side.

The future of the web application architecture cuts the picture of more interactivity, more predictability, more security and more value to the user. Similarly, the whole application infrastructure like A/B test capability, analytics, automated deployments, no crashes and self-healing properties.
