The Internet is no longer characterized by static web pages and lengthy loading times. Over time, the Internet has shifted toward active user participation and expanded functionality through the deployment of aesthetically appealing and powerful web apps.

Selecting the sort of web app architecture and the model for web app components is crucial before starting a web Application development project. Making the proper decisions is crucial to a web app’s success.

In this article, we will go through Web Application Architecture meaning, types, components, and models. But first and foremost, let us begin with the meaning of web application architecture.

What is Web Application Architecture?

The architecture of a web app is the design and construction of a website or web app. It includes everything from database design, programming logic, and user interface design to user experience. The design of a web app can be a very complicated process that often involves a large team of people. The goal of web app architecture is to create a functional and efficient design that will meet the needs of the business and users.

It’s a collection of decisions about how the application will be built, how it will be deployed, how users will interact with it, and how it will evolve.

Types of Web Application Architecture

The single-page application (SPA) architecture 

Single page application is a way to build web applications that have a similar feel to traditional applications that are built for desktop and mobile platforms. The primary difference between SPA and traditional web application architecture is that the former uses a single page to serve the majority of the content on the application. This enables the application to be faster and easier to browse, which improves the user experience.

Microservices

The microservices architecture is an approach to building web apps that are designed to reduce complexity and improve scalability. The microservices architecture is composed of small units of code called services that work together to provide a single function or service. The services are independent of each other, making them easy to test, deploy, and manage.

Serverless architectures

Serverless architectures provide the freedom to focus on building their platform rather than managing infrastructure. The biggest benefit of serverless architectures is the ability to scale applications on demand, without having to worry about the underlying infrastructure.

Components of web services architecture

UI/UX Web Application Components 

These are the components that users interact with to access and use the functionality of a web app. They include the web app’s UI/UX design, which is the way the app looks and feels to users; the app’s functionality, which is the set of features and functions the app provides; and the app’s business logic, which is the set of rules and algorithms that help the app perform its functions. User interface app components help users interact with the app, providing a way for users to navigate around the app, perform actions, and view information.

Structural components

The functionality a user interacts with, the control, and the database storage are all considered structural components. It includes,

The client or web browser allows users to interact with web functions created using HTML, CSS, and JavaScript

The web application server serves as the core hub for business logic and multi-layer applications written in Python, PHP, Java, .NET, Ruby, and Node.js.

The database server stores information that is accessed by the webserver to supply data or provide services to users.

Models Web Application Components

One database, One Web Server

One web server is shared by all application services, each with a dedicated database. This architecture is ideal for applications that require low latency, isolation, and high availability across multiple data centers. The only downside is the increased operational complexity. This is where the Microservices architecture can help.

One Database, Multiple Web Servers

With this kind of web application component model, no data is kept on the webserver. The web server receives data from a client, processes it, and then inputs it into a database that is run independently of the server. The term “stateless architecture” is also occasionally used to describe this.

For this web application architecture model, at least two web servers are needed. All of this is done to prevent failure. The second web server will take over even if one shuts down.

Multiple Databases, Multiple Web Servers

The most effective model is this one. There are two possibilities available to users of the multi-server model: either they may store all of their data in the employed databases, or they can distribute it among these databases.

For the former instance, normally no more than 2 databases are needed, however for the latter case, some data may become inaccessible in the event of a database crash. However, both situations take advantage of database management system (DBMS) normalization.

Conclusion

The related technologies and best frameworks advance together with the web. The outdated legacy architecture and fundamental elements have been replaced with modern web app development.

Therefore, it is crucial to pick the appropriate web development architecture, as this will affect how well the web app runs. The web app’s speed, robustness, and security, as well as how responsive it is, are crucial factors that depend on the architecture chosen.

With what may be referred to as an intelligent blueprint, the proper web application architecture lays the way for future goals of extension and scalability.
