Web Application Architecture: Fundamentals You Need to Know

Before starting a new web project, we have to go through multiple stuff. And one of that is web application architecture. Without this, you can not start off. Picking the correct web application infrastructure is the first step of web development.

Choosing the structure will define many things, such as its functionality and future growth. Admittedly, architecture isn’t something that can get easily undone afterwards, so it’s wise to spend your time discovering the optimal balance.

Today, we are going to cover the fundamentals of web application architecture in a nutshell. We will go through what web app architecture is, its primary features, and layers, including the various types of web architecture.

Let’s continue reading!

The Overview of Web Application Architecture

To grasp the fundamentals of web application architecture, we should first learn the definition of the web application.

Basically, a web service is a software app that hosts a website. Comparatively, computer-based software applications reside natively on the device’s OS or filesystem.

Now, let’s gain some idea about the web application architecture. Web application architecture is the adhesive that keeps a web service-connected. It is the foundation of a web app and is in charge of the interactions between different configuration items such as user interfaces, middleware systems, and databases.

All modules, sub-components, and external application interchanges of the ultimate web application get included in the Web Application Architecture. An application’s architecture allows software developers to identify software systems rationally.

 The main purpose of web application structures is to execute requests based on specific aims and needs efficiently.

 This sector’s market is constantly upgrading one another while consumers’ needs are evolving, making improving project design for a web application a continuous effort.

The Features of Web Application Architecture

As you begin thinking about real development, give it time to become acquainted with architecture development standards. Here we created a checklist of the important features.

  1. Scalability

The infrastructure also plays a role in the web’s horizontal scaling. The architecture handles the need for traffic-related spikes by utilizing numerous servers spread across territories. In terms of bandwidth allocation, Cloud Services are becoming a norm.

  1. Efficiency

The execution of web-based applications architecture includes analyzing an app’s observed and predicted capabilities, potential improvements, and efficiency monitoring, consisting of a row of indications.

Furthermore, it enables the evaluation of optimization results and the use of measurement tools. These are the key component of this section.

  1. Security

We are all aware of a web app’s insecurity, so security is becoming increasingly vital. The primary worry is malicious payload exploitation.

As a result, the app must follow government regulations that ensure data protection and safeguarding.

  1. Extensibility

Extensibility is a notion in the web application system that enables the answer to be expanded and advanced. It indicates the solution’s capability to grow and the time and effort required for this procedure.

Further, extensions can be developed in two ways: by implementing new technologies or enhancing existing ones. The fundamental idea is to create software while preventing the decay of previously constructed pieces.

  1. Separation of Responsibilities

When it comes to features, an application should be flexible and self-contained. This aids programmers in problem-solving and incorporating innovations into the web app.

Furthermore, because of its minimalism, the web app is a key aspect of the architecture that can be dynamic, interesting, efficient, and troubleshoot bugs. In addition, stats, automatic release, and A/B testing are available.

Types of Web Application Architecture

Web servers are critical to the effectiveness of a successful web app. As a response, when presenting web application design principles, we must first address web server architecture.

Several factors determine the type of server to use, including the application tier, pace, space, and computing power. The main types of web server architecture are as follows:

  1. Micro Services

These systems are lightweight and durable, providing only a single process. Microservice design has numerous advantages for both users and developers.

This innovative web application architecture increases efficiency and speeds up continuous delivery.

One of the most appealing aspects of such a service architecture is that programmers can use any software system as attributes that make the app interdependent.

  1. Single-Page Applications

Single-page applications are good since they do not disrupt the consumer experience. It’s related to why SPAs do not necessitate the loading of totally different pages each time the user takes a new activity.

Rather, updated data gets transmitted without having to be reloaded. AJAX, a kind of Asynchronous JavaScript and XML, makes single-page apps possible and provides the most interactive user engagement.

  1. Multi-Page Applications

In the past, all web pages were MPAs, but now multi-page apps are becoming more common. Companies nowadays use MPAs when the solution is quite significant (like eBay).

Such methods refresh a web page to load or communicate data from/to a server through the clients’ browsers. Popular MPAS include eBay and Amazon.

Layers of Web Application Architecture

We will discuss here four common layers of web application architecture. Let’s take a look.

  1. Data Delivery Layer

It enables quick access to the information contained in specified storage, such as XML and file formats. This layer also handles CRUD (Create, Read, Update, Delete) activities.

  1. Data Service Layer

This layer communicates with the Presentation Layer by sending data generated by the Corporate Logic Layer. It keeps the business logic isolated from the client-side, ensuring information integrity.

  1. Business Logic Layer

This layer allows for proper file transfers. It establishes the reasoning for corporate activities and norms. Joining a website is a sample of a business logic layer.

  1. Presentation Layer

This layer highlights the user interface and simplifies user interaction. It has user interface elements that convey and show data. The system is also able to provide clients with all needed data.

The application gets geared towards executing user requests, accepting input, transmitting it to the database server, and displaying the results.


Lastly, we would like to say that web application architecture will significantly impact the performance and functionality of your program.

Additionally, it describes search engine optimization strategies, user interface/user experience techniques, data management, and privacy. Ultimately, architecture is what makes the application tick.
