Fundamentals of Web Application Architecture

Fundamentals of Web Application Architecture

A web app is an application program that is saved on a remote server and delivered all over the internet through a browser interface. Web applications can be designed for a wide variety of uses and can be used by anyone from an organization to an individual for numerous reasons. Some of the web apps can only be accessed by a specific browser, however, most of them are available no matter the browser.

If we talk about the fundamentals of web application architecture then an average internet user gets to see a specific page on his/her system. And the framework is the component that connects and interacts together. This framework is known as Web Application Architecture. The various components of applications include:

i. User Interface

ii. Databases

iii. Middleware Systems

iv. Servers

v. Browser 

As we all know that mobile has become a preferred choice for the users, the need is for web app development and architecture that meets your requirements across all platforms. And since we are moving ahead, the app development is becoming more complex and it is becoming more difficult for the developers as they veer towards full-stack development architecture.

Web Application Architecture

Workings of Web Application Architecture

Let us understand it in very simple terms, we apps include two different sets of programs that run separately yet simultaneously with a simple goal of working together to deliver solutions. The first set of programs include the code in the browser which works as per the inputs of the user and the second set of code is in the server which works as per the requests of protocols, the HTTPS. So, the developers from the Web app development agency need to decide on the functions of the code on the server and simultaneously the code on the server and the functions of the code on the browser. And most importantly how will these two functions work in relation to each other.

What are the Three Types of Web Application Architecture

Single Page Applications(SPA)

These types of web application architecture include single-page web apps and they are very popular at the moment. This type of web development includes an impressive and interactive user experience. The single-page web apps allow you to create more dynamic interaction and make things easier for the user.


It is a really helpful web app architecture as it helps with the execution of a single and specific functionality through microservices. It also allowed developers to roll out applications quicker with great efficiency. As you know that different components need to be developed in different coding languages, but with a microservices architecture framework you get greater flexibility in choosing a technology of choice.

Serverless Architectures

This allows apps to execute without a correlation to infrastructure-related tasks, where the developers do not have to manage the backend servers, working on third-party infrastructure.

When it comes to website development then its architecture matters a lot just like in mobile app development. There are a series of interactions between various components of applications, user interfaces, middleware systems, databases, servers and the browser. And a framework ties up the relation interaction together in web application architecture. So, it becomes important to understand the architecture. So, here we have the fundamentals of web application architecture.


Components of Web Application Architecture

Web Application Architectures consist of several components that are segregated into two categories of components. The first one is user interface app components and the second is structural components. Let us have a look at them one by one:

User Interface App Components

This component is really important for web pages that want to incorporate amazing displays, settings, and configurations on their site. User interface app components are related to interface, rather than the development as it deals with display settings, dashboards, notifications that users see, and also the logs.

Structural Components

The structural components of a web application refer to the functionality of the web application with which a user interacts, the control, and the database storage. So, we can say that it has more to do with the structural features of web architecture. It comprises the web browser or client, the web application server, and the database server.


Web Browser or Client – It allows the users to interact with the functions available on the web apps that are usually generated using HTML, CSS and JavaScript.

Web Application Server – It usually handles the mid hub which supports the basic business logic on other multi-layer applications. It is developed using Python, PHP, Java, Ruby and Node.js.

Database Server – It offers business logic and relevant information that is stored and managed by the web app server. It basically stores, retrieves and provides the information to the user.

Web Server Architecture

By all definitions, this refers to the ideal layout of a web server, which will assist the design, development and deployment of the webserver. Its main motive is to make the web apps work, and mandate the need for increased emphasis on web server architecture. It includes the server’s physical capacity storage, memory, computing power, and performance, apart from the app tiers. It can be anywhere in the components – either inside the server, across the network, or the operating systems. The different types of web server architecture include:

Java Web Application Architecture

Java is one of the oldest and most versatile programming languages which is popular among the best Web app development company and web developers. Now when using Java, the complexity of the solution will depend on the nature of web application architectures. So, the solution could either be simple or multi-tiered applications.

Irrespective of the complication in the application, Java Web app architecture is the preferred platform for the developers for the native development and deliver the most amazing applications. The most unique benefit of Java Web App Architecture is that it has the ability to combine and rely on the Java native tools and frameworks to develop applications sitting on the entire spectrum.

Cloud-Based Web Application Architecture

The migration to the cloud is important these days instead of a choice, as it offers some of the best benefits which help businesses in terms of development. That is why cloud-based web application architecture has been developed. The cloud-based apps function and store information on local servers and the cloud.

Node.js web Application Architecture

Node.js is an open-source, cross-platform, back-end JavaScript runtime environment that runs on the V8 engine and executes JavaScript code outside a web browser. The Node.js web application architecture lies in the pattern of model view. For example, the model view controller, the Model view model, and the model view presenter.

Node.js allows the creation of patterns for the purpose of identifying code elements and apart from routing it is also used to configure the elements. Another advantage of Node.js web application architecture is that it helps build scalable web apps. Node.js also relies on entity relationships which helps to ensure that the application runs seamlessly, through data systematization, breaking logic into modules, dividing the code, along processing valuable insights from logs. 

Node.js is an open-source, cross-platform, backend JavaScript runtime environment that runs on the V8 engine and executes JavaScript code outside a web browser. And the demand for Node.js is on the next level as developers are using it more than PHP. There is an authority of node.js-based frameworks when it comes to web app development but which one do the professional app developers suggest?
