Before starting a new web app project, you might get confused about picking the most apt web app architecture. The chosen architecture determines all specifics of developing an app, its functionality, & the interaction of its components. You must select the right pieces for your project’s success.

This article will shed light on the basics of web app architecture. Here we will talk about types, significant components, models, and features of web app architecture. Let’s get going!

Define Web App Architecture

It’s a framework that links various elements to qualify the web experience. It’s the basic of our regular web browsing.

One of the best ways to describe web app architecture is: typing a URL and viewing & interacting with the site when the browser communicates with the server.

How Does Web App Architecture Run?

Every web app has 2 parts - back-end (server) and front-end (client). The app’s visual aspect is the client-side. Users can interact with an interface as they can see it. Whereas users can’t look at the back-end, but it works on their command. It handles the business logic & answers to HTTP requests too.

Therefore, while filling the registration form, you manage the client-end, but when you tap ‘enter’ and get registered, the server-end runs it. If it goes well, server and client ends can create web app architecture.

Main Components of Web App Architecture

UI App Components

UI components are related to the display, settings, and configuration in the app. UX or UI is a significant part of this component instead of its function after web app development architecture. It includes the display of dashboards, notifications, logs, and configuration settings.

Structural Components

These components include the functions that determine user interactions. These even include database storage & control. The architecture in these components is mainly for three parts: the web browser, the web app server, and the database server.

Models of Web App Architecture

models of web app architecture

Several models are available to choose from when it comes to building the components of web app architecture.

1. One Database & One Web Server

This is the most simple model. An app’s effective operation depends on server stability. Therefore, the app will fail to work if there is a problem. However, the model is enough for testing and private sessions.

2. One Database & Various Web Servers

This is the most reliable model, as it has a backup server. Ensure the database is continuously running & protected.

3. Various Databases & Web Servers

This is the most trustworthy option. Due to its capacity for managing & processing vast amounts of data, this model is a strong base for building enterprise web app architecture.

Types of Web App Architecture

1. Single Page App

This web app includes a single page architecture that only has content elements. It renders the best UX with robust interaction. Users can just access a single page in a better way.

2. Multi-Page App

These apps are more desired on the web. These days businesses choose them in case their sites are massive. These solutions reload a site page for loading or sending data to or from a server via the users’ browsers.

3. Microservices Architecture

Microservices architecture focuses on a specific function and single page application for faster rollout and productivity. It is easily developed with codes that render the superior quality to the app and can be flexible.

4. Serverless Architecture

Serverless architecture has no infrastructure or correlation related tasks. Here, developers can work on the 3rd-party infrastructure instead of back-end server handling, thus making it easy for developers to apply the web app.

5. Progressive Web Apps

These web-based solutions are created for working like native apps on mobile devices. They render push notifications, offline access, and a chance for downloading an app to your home screen.

Features of Web App Architecture

1. Security

We all know web app’s weakness; hence, security becomes crucial. Harmful code manipulation is the primary concern. Therefore, the app must be secured for keeping the data secure as per government laws.

2. Scalability

This feature includes several regions & servers to manage the possible traffic or any type of change.

3. Extensible

Web app architecture’s lifetime is essential for mobile app creators. The modern web app architecture must have a steady and long lifecycle.

4. Separation of Concerns

An app should be independent and compatible with components. This helps developers resolve issues and include features in the web app. Also, the web app’s simplicity makes it an essential part of the architecture that can be unique, quick, responsive, and problem-solver.

How to Design Web App Architecture

how to design web app architecture

The primary aspects that you must consider while designing web app architecture are as follows:

  • Target audience
  • Budget
  • Architecture objective
  • Targeted platforms
  • Development timeframe
  • Web solution features and scale

1. Database

Here, you must choose the one that renders multiple features such as NoSQL and SQL. NoSQL is regarding key-value structure, objects, and more, whereas SQL concerns predetermined plans & tables.

2. Back-end

Here, you must choose a relevant platform regarding the static & changing nature of the domain. Pick the server & language that go perfectly with each other. There is a choice of microservices or serverless web app architecture that you can achieve with cloud services for memory needs and CPU.

3. Front-end

Choosing between the model view controller & the single page app is another factor about the web app architecture. Before selecting the type of architecture, consider the needs & what will be suitable in both cases.

4. API

API is another critical design factor that depends on REST, POST, and GET. These APIs can manage the HTTP request easily.

There is also GraphQL that is included by Facebook that allows us to bring in objects from the server & make slim calls.

There is also an option of PC communication incorporated in WebSocket that moves messages to the client from the server.

The Bottom Line

Web app architecture is necessary for each web-based solution. Therefore, its achievement highly depends on how properly it is assessed and developed. Hence, stand tight as per your tech requirements and goals of your web solution, and your product will function adequately, appeal to the right audience, and enjoy the perks.
