What Is Web Application Architecture?

Web application architecture is the design of simultaneous interactions between components, databases, middleware systems, user interfaces, and servers in an application. It can also be described as a layout that logically defines the connection between the server and the client side for a better web experience.

Web application architecture

  • Consisting of presentation, business, persistence, and database layers, the web application framework is layered. Small applications that consist of one layer have the business and persistent data layers as a single unit, while large applications have five or six layers.
  • The presentation layer consists of HTML, CSS, JavaScript, and their frameworks, which provide the HTML template for the presentation layer and enable interaction between the interface and the browser.
  • Business logic and rules reside in the business layer. This is where the browser request is processed, followed by the execution of the business instructions given in that request, and then passed to the presentation layer.
  • The data persistence layer is part of the persistence layer and is also known as the data access layer. It connects to the business layer and manages data storage in addition to loading data.
  • The business logic is connected to the client side through a database layer that protects the integrity of the data by separating it from the business.

Web application components

  • Web application UI/UX components – These include activity logs, dashboards, alerts, settings, statistics, etc. These components have nothing to do with the operation of the web application architecture. Instead, they are part of the web application’s interface layout plan.
  • Structural components – The two main structural components of a web application are the client side and the server side.
  • Client component – ​​The consumer thing is evolved in CSS, HTML and JS. Because it exists in the user’s web browser, there is no need to modify the operating system or device. The client component represents the functionality of the web application with which the end user communicates.
  • Server component – The server thing may be constructed the usage of one or a mixture of numerous programming languages ​​and frameworks, together with Java, .Net, NodeJS, PHP, Python, and Ruby on Rails.

Types of web application architecture

Single page application architecture

SPA tries to overcome the classic difficulties of creating smooth applications to provide an easy-to-use and intuitive user experience. SPA overcomes these difficulties. SPA loads a single web page and updates the data on that page with dynamically generated content instead of loading a new page.

Microservices architecture

Monolithic architectures are now being superseded by microservices architectures, which are built on a large number of services that can operate asynchronously to solve complicated problems. Because APIs are used to communicate between services, they are loosely coupled.

Serverless architecture

Cloud service providers such as Amazon and Microsoft manage servers that use serverless architectures, so no manual intervention is required on the server. Serverless architecture is a design pattern in which applications are built and run without any human intervention on servers managed by third-party cloud service providers such as Amazon and Microsoft.

Conclusion

The architecture of a modern web application must always keep up with changing requirements. Keeping up with current requirements is hard work and a small mistake can cost you the life of your product.
