What is Web Application Architecture, Components, Types, and Best Practices

Web Application Architecture

This guide to web app development briefly covers the basics. We’ll be discussing what web application architecture is, its main components, and the various types of web app architecture. Our comprehensive guide will give you a solid understanding of web app architecture.

What Is Web Application Architecture?

The web application architecture is a way to connect different elements and create a seamless experience. It is the foundation of internet browsing. One way to explain web application architecture is by typing in a URL, viewing the site, and interacting with it while the browser communicates directly with the server.

The attributes of a well-built web app architecture:

  • Solutions for business problems
  • Supports visual aesthetic
  • Analytics and A/B testing are possible
  • Ensures fast user experience
  • Security
  • Self-regulating and sustainable
  • Easy way to scale out and log errors
  • A high level of automation guaranteed

Components Of Web Application Architectures

Application components, middleware, and databases are the core of web application architectures. You can divide them into two groups.

  • UI/UX components
  • Structural components

UI/UX elements include notification elements, dashboards, statistical information, notification elements, and layouts. These components are responsible for creating the visuals on a website and laying the foundation for the user experience.

structural includes the web application server as well as the database server. To create them, you will need to have knowledge of HTML, JavaScript, and CSS as well as Python and PHP, Java and Ruby,.NET, and Node.js.

There are many models available for building components.

1 webserver, 1 database
2 web servers and 2 database
More than 2 web servers or databases

The simplest model is one web server and one database. This web server architecture is crucial for the smooth operation of any application. The server’s stability is what will make the application work. The model can still be used for private sessions and testing.

The one database model for two web servers is more reliable since there is always a backup server. It is also important to ensure that the database is always up and running.

More than two databases or web servers are the best options. This model is ideal for enterprise web applications because it can handle large amounts of data.

Types Of Web Application Architecture

There are three types of web application architecture. Each type has its advantages and disadvantages and serves different purposes.

  • Legacy HTML web app
  • Widget web app
  • Architecture for a single-page web application

Legacy HTML uses very basics logic. A user is able to request the entire HTML. It refers to web server architecture in which all elements, namely web page logic, and the overarching business logic, respond to a full reload. This web application architecture works well for static pages but not dynamic web apps.

A widget is a more advanced type that allows you to load data without having to request a page reload. This web application architecture type allows widgets to send AJAX queries, and receive data in HTML or JSON. This widget web app type is better suited for mobile apps. Widget apps have security issues and take a long time to develop.

A single-page web application architecture allows users to simply request the page. This web app architecture relies on server requests in JavaScript and HTML, instead of exchanging data using JSON.

Web Server Architecture (website server architecture)

Web servers are crucial for the success of web apps. This is why web server architecture deserves special attention in the web architecture topic. Performance indicators such as speed, storage, processing power, and app Tiers (number and quality of connections established between various applications, operating systems, and networks) are used to select servers.

Let’s now look at the different types of webserver architecture.

Java Web Application Architecture

Java-based web architecture allows for maximum flexibility. It can be used to create both simple and complex pages. Java web architecture is able to build a reliable web app with a long-term view. This is crucial for any web application architecture.

A wide range of Java-based tools is available for web application architecture design. Java web architecture developers and businesses have the flexibility to achieve their goals.

Cloud-Based Web Application Architecture

Cloud-based web applications were born out of the trend to move operations to the cloud. Data decoupling is a major benefit of cloud-based web application architecture. A cloud-based app can run on both a local server as well as in the cloud and it is stored on both. Cloud-based web applications architecture allows access to app data and identity management.

Node.Js Web Application Architecture

Node.js web application architecture relies on model-view patterns, including MVC (model-view-controller), MVVM (model-view-view-model), and MVP (model-view-presenter). These patterns are used to identify code elements and provide a way to route them and configure them. Node.js allows you to create a directory and design patterns.

Node.js web app architecture uses an entity-relationship diagram to data systematize, divide the code into modules and process valuable insights from logs. This ensures that the application runs smoothly. Node.js allows you to build scalable web applications.

.NET Web Application Architecture

.NET web app architecture is essentially cross-platform support, microservices, and Docker containers. It also allows for side-by-side versions. Data Access Layer in the framework allows you to use stored data without having to apply a particular database code. This type of web architecture today includes ASP.NET Core (formerly.NET Core), which greatly enhances the language’s functionality in terms of optimization and support.

PHP Web Application Architecture

PHP is a popular web development language. It’s also one of the most simple and functional. A PHP web application architecture guarantees faster development, better security, and clear maintenance. It also allows for support from large communities.

Azure Web Application Architecture

Microsoft Azure web app architecture lets you design a solution that can be used as a bridge between traditional tools, and the cloud. Azure cloud platform uses the most advanced web application architecture practices.

AngularJS Web Application Architecture

Finally, AngularJS serves as both a platform and a framework to support HTML and TypeScript. This web architecture is built on Ng Modules, which are building blocks. Its key benefit is lazy loading. This improves the user experience and reduces code size.

Laravel Web Application Architecture

Laravel is a PHP-based framework that provides a rich and expressive syntax. It implements the Model-View-Controller (MVC) architecture and offers software engineers a simple web development experience.

Engineers can use Laravel’s web architecture to create seamless applications. These features include modular packaging, better routing and authentication, caching and sessions, and many others that allow developers to maximize performance and increase traffic. Laravel allows you to create multiple routes using unique URLs. The architecture helps software engineers complete their web projects quicker.

Python Web Application Architecture

Python is a well-known web development language that can help you create a secure architecture for your web product. It is easy to understand and concisely codes server-side scripting. This makes it accessible for those who are just starting to code in Python, or working on their first web application project.

Python supports a number of tools that can be used to maintain your web application architecture. This is in addition to speeding up the development process. This programming language is ideal for prototyping because it’s dynamic and uses shortcodes. You can combine multiple Python frameworks in one web app project, or you can use other programming languages.

Web Application Architecture Diagram

This is an example of what a web app architecture diagram looks like.

Here’s how a web app works from the user’s side and underneath the hood.

  • The user creates a request by entering the URL in the address bar of a browser.
  • The browser retrieves the user’s request, determines its location, and requests access.
  • The browser receives the request data from the server
  • The browser interprets the information received and displays it to users as a website

Best Practices In Web Application Architecture

A web application architecture that is ideal should be easy to use and maintain. The best practices to design web app architecture include the following:

  • Scalability
  • Efficiency
  • Problem-solving is seamless
  • Flexibility
  • Reusability
  • Rapid testability
  • Decipherable code

Developers can now create solid web apps architectures for any digital solution thanks to technological advancements. These are the top web app architecture trends for designing and developing a web-based application architecture.

Service-Oriented Architecture

A service-oriented web application architecture is software that can be used to provide a service for other companies. Service-oriented architectures have their own HTTP API. They can run on multiple servers simultaneously and work together by sending each other requests. Creating software-as-a-service (SaaS) products is a long-established trend that stayed essential throughout the years.

Single-Page Applications

Because they are less likely to cause page load interruptions and are easier to develop, single-page apps are growing in popularity. This web app has a one-page design and objects are stored in tables linked to an SQL database. Every user action loads an object from the site dynamically without having to reload the entire page. The back end is handled via AJAX web-development techniques or the WebSocket computer communication protocol.

Progressive Web Apps

These apps support all modern web browsers and offer enhanced offline support with improved cache management.

Progressive web apps are becoming more popular due to increased smartphone use. These apps are similar to regular websites, but they can be viewed on mobile devices.

A progressive web app is simply a website that looks like a mobile app and can be accessed in a browser. It does not have to be downloaded from an app store. This app type is compatible with most modern web browsers. It also provides solid offline support and better cache management.

Progressive web apps are able to reach a wide audience, even if they don’t have the latest apps on their phones.

These apps support all modern web browsers and offer enhanced offline support with improved cache management.

Prioritizing Search Engine Optimization

Google’s latest algorithm updates also consider web app architecture when ranking websites for SEO. Google crawler supports websites with an easily-understand hierarchy.

Developers who create progressive web apps must also take into account mobile search rankings when designing the architecture.

Blockchain Network

Blockchain technology can be integrated into your web application architecture to make it secure and fail-safe. Decentralized load balancing is also possible with blockchain technology since any blockchain system is distributed over a network.

How To Design Architecture For Web Application

Before you start designing a web app architecture, consider these key points:

  • The web project’s goal
  • How your web solution will scale, and future possibilities
  • Target audience
  • Timeframe to create the web application architecture
  • Features of Web Solution
  • Platforms are the solution that will work across all platforms
  • Budget

After carefully considering all of the above, you can now design and implement the web app architecture that you have chosen. These are the important things to keep in mind as you move forward with this task.

Backend Development:

Language: Select a language that is relevant to your domain.
Framework/Server Select a server that supports your chosen language.
Serverless/Microservices: You can also choose a serverless web app architecture by using the cloud storage of one of the cloud services providers for your CPU and memory needs. Microservices are used by some organizations to make their web solutions run on multiple servers that communicate via HTTP or Queue. This model supports multiple languages.


SQL/NoSQL – SQL databases and NoSQL databases offer different features. SQL databases come with tables and a predefined plan. NoSQL on the other hand has objects, key-value structure, etc., and is more flexible and scalable which makes them ideal for large-scale projects.

Replicability Replicable Databases have better load management because the data is copied into clusters. Backup You should have a backup of your database.


API Design The most common API design styles are REST, POST, and GET. These allow you to manage HTTP requests. Facebook introduced GraphQL, an innovative way to design APIs. This allows for lean calling by retrieving multiple parts from different objects from the server in one call. This is especially useful for mobile apps with limited internet bandwidth.

WebSocket – WebSocket sends messages to the client from servers in order to inform them about new data. WebSocket can be useful but is not mandatory, especially if the app doesn’t need to keep clients updated frequently.

Front-End Development:

Choose from Model View Controller (MVC), Single Page Application(SPA), or Server-Side rendering (SSR).
Platform: Vue, React and Web Components technology suites are the most popular platforms for front-end programming.
These are just a few of the key considerations. Other things to think about when designing your web app architecture include cloud storage, security, and app processing power.


The web application architecture is the foundation of any web-based solution. Its success is dependent on how well it has been thought out. Your product will be able to meet the technical requirements and reach the intended audience.
