by Nathan Zachary

Redefine, organize, and scale your organization with an antidote to web development services for lucrative outcomes and development.

These days, both users and developers are obsessed with web applications. The era in which native applications were prefer is long gone, and with the emergence of web app technologies, the landscape of mobile app development has undergone a full transformation.

Before selecting web application architecture for your project, you must take into account a number of factors. Your choice may be affect by the demands for scalability, the scope and objectives of your projects, and even the organizational structure.

Let’s go through some latest statistics related to the market of web applications.

The global market for progressive web applications was worth $1.13 billion a few years ago, but it has recently begun to gather tremendous pace and might reach $10.44 billion by 2027, with an astounding CAGR of 31.9 per cent.

According to Statista, there were 4.66 billion internet users in January 2021, where 4.32 billion people are using mobiles and other gadgets that are accessible to the internet.

What is the purpose of Web Application Architecture, and why is it Crucial?

Software architecture, in general, relates to the layout, structure, and key elements of the system and establishes how those elements interact and communicate with one another.

Consumer expectations, particularly for their online experience, have increased dramatically with the introduction of web technology and the availability of smartphones (both web and mobile).

Users are significantly influence by the usability, credibility, usefulness, desirability, and value of their online interactions and experiences.

Although the user cannot see the architecture of a web application, the decisions made at the architecture level can undoubtedly affect the user experience.

What are the components of web applications?

Various application components make up the web app architecture, which dictates how the programme will operate including Security, Authentication, user experience, automation, speed and reliability, analytics and testing, scaling, and error logging.

When we discuss the fundamentals of web application architecture, we first outline the connections between its major structural components:

  • A browser-based client programme that users can access,
  • A web server that handles requests and returns results,
  • Databases that hold and allow access to data
  • Using the cloud (for cloud-native solutions),
  • Integrations with third-party APIs, etc.

What is the type’s web application architecture?

2-Tier architecture

It is based on a client-side system which usually incorporates a database server. The businesses are usually incorporated into the user interface or database server. The downfall of 2-tier architecture is that it decreases its performance when the number of users increases.

3-Tier architecture

It is based on separate applications such as presentation tier, application tier and data tier. Each of the tiers runs on its own application and can be develop by different teams. This kind of structure allows us to update and scale every tier without impacting the other tier.

SPA- Single-page application

A SPA provides the user with only one web page that changes completely when the user clicks something or interacts with the page. Whenever the user clicks the page, instead of reloading the SPA updates only the required component making the entire web app fast, lightweight and instantly responsive. The famous examples are Facebook and Gmail.

SSR- Server Side Rendering

The client-side receives the data from the server in the form of a filled-out HTML page. We used to face load delays, but since introducing dynamic routing to send only the data needed for the following pages, SSR has greatly improved. The extremely well-liked React takes this tack.

CSR- Client Side Rendering

In this design, JavaScript is use by the browser to process and render the web application inside the browser. Developers employ general-purpose languages for the website server architecture, which are understood not only by browsers but also by other devices.

Serverless Architecture

With this design, scalable and high-performance online applications may be develope without having to worry about maintaining or setting up the servers and other computing resources that power the programmes or databases, such as those from Azure, AWS, or Google Cloud.

Multilayer Architecture

This architecture uses tiers and layers independently. This design allows for unrivalled resilience and allows each service to operate and scale to its full potential. You may have many tiers for user interfaces for mobile, online, or desktop systems in an n-tier architecture system.


A JavaScript solution named Isomorphic is based both on Front-end and Back-end. When the Javascript application is upload to the browser, the HTML is loaded by the client and it exactly works like SPA.

Monolith Architecture

A web application that performs all or the majority of the functions is known as a monolithic web application. It has layers of data, display, and business logic on the inside. It can be share with in-house servers or even in the cloud yet has an un-dividing characteristic.

Progressive Web Apps

A page created using the progressive web apps methodology functions as a cross between a website and a native mobile app. The software behaves like a mobile app even though it was develope architecturally as a web page.

What are the layers of web application architecture?

A layered modern web app architecture helps you to select the role of each component and make changes in accordance with the layer without changing the overall application. It helps you to easily write, manage and re-use the codes.

Below are the typical layers of website application:

PL- Presentation layer

The user interface is seen by the Presentation layer which makes the interaction more upfront. The UI components handle the display information for the user. PL provides all the necessary information to the front-end.

BLL- Business logic layer

This data is use for correct data exchange. The business logic layer, which also goes by the names Domain Logic and Application Layer, handles the processing of client requests coming in from the browser and directs users to the information they need.

DSL- Data service layer

DSL moves data from the Presentation layer to the Business logic layer. By separating business logic from the user-side, DSL protects the data of application web architecture by passing the information processed by BLL to the Presentation layer.

DAL- Data access layer

DAL gives the facility to save the data in binary XML files etc. it also performs operations of creating, reading, updating and deleting. The storage and presentation layer is merge with the business layer.

Famous Web Server Architecture

Databases, middleware platforms, and application components make up the architecture of web applications. The structural and UI/UX components of an app are further divide into two categories. Dashboards, statistical information, layouts, notification elements, etc. are among the UI/UX web app structure components.


It is the most popular technology for building architecture for web apps. Its web app architecture design provides a wide range of Java-based tools. Because it enables the construction of a dependable and adaptable framework for the long term, this language can be use with any scale app design.


Another popular technology for creating web app architecture is Python. For server-side scripting, it has a script. For web developers that are either new to Python scripting or are creating the architecture for the first time, this tool is a suitable solution.


With the help of model-view patterns, such as MVC (model-view-controller), MVVM (model-view-view-model), and MVP, Node.js can be use to build model-view-based web applications (model-view-presenter). Its advanced web app architectural patterns include the ability to define, configure, and direct script elements.

AWS Web Application

One of the most widely utilized cloud solutions for implementing popular patterns like microservices, mobile backends, and single-page applications is AWS serverless services. The below diagram demonstrates how the earlier described three-tier design logic may be apply to create a web application utilizing AWS web services.

Azure Web Application

You may create simple and secure serverless web applications using a range of cloud computing capabilities offered by Azure. Azure App Service and Azure SQL Database are use to creating a simple web application.

An Azure App Service web application’s scalability and performance are enhance by the use of Web App, Front Door, Function App, Azure DNS, Azure Cognitive Search, and Azure DNS.


To win customers’ trust in the highly competitive world of software today, businesses must offer more than just high-quality goods and services. The most important factor is how you provide your customers better services. Web-based tools make this possible.

Top Web Development companies in India develop and implement highly optimized web apps that cost-effectively provide clients with a superior UI/UX experience as well as speed and performance. Here, choosing the appropriate web development agency or web Development Company is essential.
