What is Web Application Architecture | How Does it Work?

Modern software application systems have reached such a high level of development that the term “web application architecture” is now also associated with it. Developing an effective and reliable information system from the ground level is as difficult as building a high-rise apartment structure.

Over 50 million people use the Internet daily, so we can’t imagine the world without the Internet today. Every entrepreneur who wants to grow his business and make a profit goes online.  An app is a useful tool that helps your business increase traffic, attract customers and increase revenue.

We know, you are curious to learn more about web application architecture !!!

Here we’re giving you a guide so that you can easily understand Web Application Architecture.


What is Web Application Architecture?

To ensure that an application can operate together, web application architecture describes the relationships between apps, middleware systems, and databases.

When a user types some queries on the browser and clicks on the search button; The browser immediately starts finding live web or app and gets the deep result (as a particular page).

The server also responds to the browser and sends the page data. Then User can enable to see the best result of its query and open the result.

Now in the next step users interact with the website or app and also with its layout.

The thing is it only takes milliseconds or even less time. 

The most important part is coding. The code you develop for building an app or web, do proper interaction with the browser, server, and with its keywords.

So, as you can read Web Application Architecture includes all the internal and external components to make the relationship between the entire Web Service Architecture.

Of course, this makes you satisfied when you are getting your demands and objectives.  

It operates effectively while satisfying its unique demands and objectives. Web application architecture is essential because web-based communication is used by most global network traffic and by every app and device. It addresses issues of scalability, efficiency, stability, and security.


How Does Web Application Work?

In Web Application Architecture, it works on the server vs. the client-side.

In it, 2 programs are running parallel. 

1) The code that runs in the browser and reacts to user input.

2) The server-side code that replies to HTTP requests.

Server-side code includes languages likes Javascript, Python, C#, PHP, etc.

It also includes some Stores data such as user profiles, tweets, pages + user-requested pages for email or other reasons.

Client-side code includes CSS, Javascript, HTML languages. This code is developed by the user, which communicates only through HTTP requests and reacts to user input.


Application Architecture Types

The development process works on both the front-end and back-end sides. The Web Application Architecture includes both these sides.


1. Frontend:


Frontend Development


•  Single-Page Application (SPAs)

Single-Page applications make for programmers’ work. A user does not need to load works networks pages every time. He or she performs an activity on a website. Instead, customers may interact with it to receive updates to the current page.

This type of architectural web design is designed in such a manner that it just asks for the most essential material and data. As a result, SPAs eliminate disruptions to user activities, resulting in a more natural and dynamic user experience. But, the most frequent programming language in this sort of design is JavaScript.


•  Server-Side Rendered Application (SSR)

On the server, Server-Side Rendered Application is converting a client-side Javascript framework webpage to HTML and CSS. With the help of this, it is possible to swiftly supply the most critical assets, therefore increasing the browser’s performance and reducing the time to render the page for the user.

When you create an SSR app, the server compiles all the data and provides a new HTML page with each request. And, once the CSS is loaded, the browser may design the UI without having to wait for JavaScript to load. This is how the website loads faster.


2. Backend:


Backend Development


•  Microservices

Microservices are a subset of SOA (service-oriented architecture). Microservices are tiny and lightweight services that perform a single purpose. This sort of web architectural design is effective and efficient. With its help, developers may save a significant amount of time.

Because the components of the microservices are not developed in the same programming language, they are not interconnected. It implies that developers may use whichever technology they choose, making microservices architecture development faster and easier.


Serverless Architecture

Serverless architecture, as the name suggests, works without servers. It means that configuring and administering management software-powered servers is no longer required. 

However, third-party companies sustain the entire infrastructure. A third-party supplier provides an outsourced server as well as infrastructure management.

In this type of web application architecture, an app developer works with a third-party could infrastructure services provided to outsource the server as well as maintain the infrastructure.

If you’re not interested in managing and supporting servers and hardware, serverless architecture is a gift. This method is excellent since it allows you to run the code logic while leaving the infrastructure free.


Importance of Web Application Architecture:

It is critical to have strong web application architecture because it serves as the roadmap for future development, which may result from increasing demand, future functionality, and higher dependability needs.

The organization structure of web application architecture describes how an application will work exactly using object-oriented programming. 


Some important features include:

• Delivering persistent data via HTTP in a format that client-side programs can understand 

• Create new updates and delete old records

• Ensuring that queries include correct data

• Provides user authentication

• Based on permissions, restricts what people can view


Web Application Architecture Trends 

As technology advances, the usage and design of service-oriented architecture are becoming a web application architecture trend. As services, this is where the majority of the application’s code is located. In addition, each includes an HTTP API. As a result, one aspect of the code might request another aspect of the code–which may execute on a separate server.

A single-page application is another popular trend. This is when a complex JavaScript application is used to display web UI. It then remains in the user’s browser because of a variety of activities. In terms of requests, it employs AJAX or Web sockets to send asynchronous or synchronous requests to the webserver without requiring the page to be loaded.

With the two mentioned trends, web applications are now much more suited for viewing across many platforms and devices. Even if most of the code for the apps stays unchanged, they may still be seen clearly and simply on a smaller screen.


Necessary Attributes For Good Web Application Architecture:

You may a good functions for an app, but you required solid web architecture to stand out in the competition. For it, you required following certain qualities:

• Solve user’s requirements easily

• Make it unique with a simple UI design

• Make sure that it supports all the latest updates, including A/B testing and analytics

• Its loading is less

• Use safety standards to decrease the risk of penetration attack

• It does not crash and Heals itself

• There is No Point in failure

• It scales out easily

• It makes known data easier to generate

• Automated deployments

Although the architecture of web applications is extremely important, do not forget to review our archives for BuildBetter for more advice and information on better applications for planning to post-production.

The above elements are important because the right features allow you to develop the best application.

Also, with horizontal and vertical extensions, and software deployment, your application becomes more efficient, user-friendly, and reliable.



Architecture is the most important factor in the success of a web application. More accurately the web application architecture gets fast and secures web-based communication for users. Your program may work without a proper web architecture, but remember – it will be light years behind in the competition for applications with a specific architecture.
