While starting a new web app project, you may get confused about choosing the right web application architecture. The chosen architecture decides all specifics of creating an app, its functionality, and the interaction of its elements. However, for a project’s technical success, you need to choose the right components.
This guide briefly describes the basics of web application architecture. We will discuss what web app architecture is, the types of web app architecture, its major components, models, and layers, as well as the types of web server architecture. Let’s read on!
What is Web Application Architecture?
Web application architecture is a framework that connects various elements to empower the web experience. Additionally, it is fundamental to our regular internet browsing.
One of the best ways of explaining what web application architecture is: typing in a URL and viewing as well as interacting with the website when the browser creates a communication with the server.
To get a better understanding, here’s a small working of web application architecture:
Properly built web application architecture’s attributes include:
- Offers security
- Fixes business issues
- Makes sure quick user experience
- Allows A/B testing and analytics
- Backs visual creative
- Assures a high automation level
- Logs and scales out glitches easily
- Self-regulating and sustainable
How Does Web Application Architecture Work?
Every web app contains 2 parts – server (back-end) and client (front-end). The app’s visual part is the front-end. Users can interact with an interface as they can see it. Also, the client-side code responds to user activities.
On the other hand, users cannot visualize the back-end, but it works on their requests. It manages the business logic and responds to HTTP requests also.
Hence, if you fill your credentials in a registration form, you manage the front-end, but when you click ‘enter’ and get registered – the back-end makes it work. If worked well, both server and client sides can create web application architecture.
Prime Components of Web Application Architecture
There are mainly two types of components of web application architecture:
1. User Interface App Components
User Interface components are associated with the configurations, display, and settings in the app. UI or UX is the major part of this component rather than what it will function after web app development architecture. Further, it incorporates the notifications, the display of dashboards, logs, and configuration settings.
2. Structural Components
These components incorporate the functions that decide user interactions. These also include database storage and control. The architecture in these components is primarily for 3 parts: the database server, the web browser or client, and the web application server.
Layers of Web Application Architecture
There are four common layers of web apps:
1. Data Access Layer
It provides easy access to data stored in decided storage like XML and binary files. This layer also deals with CRUD (Create, Read, Update, Delete) operations.
2. Data Service Layer
This layer sends data processed by the Business Logic Layer to the Presentation Layer. Besides, it separates the business logic from the client-side, assuring data security.
3. Business Logic Layer
This layer enables appropriate data exchange. On the other hand, it decides the logic for business standards and operations. An example of a business logic layer is signing in the website.
4. Presentation Layer
This layer showcases the UI and makes user interaction easier. It has UI elements that deliver and display data for users. Moreover, it gives all necessitous data to the client-side. Its main objective is to process users’ requests, receive input data, convey them to data service, and display the results.
Models of Web Application Architecture
There are many models to pick when it comes to developing the components of web application architecture:
1. One Web Server and One Database
This is the most straightforward model. With it, an app’s successful operation relies on server stability. Hence, the app won’t work if there is an issue. But the model is enough for private and testing sessions.
2. One Database and Multiple Web Servers
This is a more trustworthy model, as it has a backup server. Hence, make sure the database is continuously running and secure.
3. Multiple Databases and Web Servers
This is the most reliable option. Because of its capacity for handling and processing hefty amounts of data, this model is a sturdy base for developing enterprise web app architecture.
Types of Web Application Architecture
The major types of web application architecture used by the design and development team include the following:
1. Single Page Application (SPA)
This web application comprises just a single-page app architecture that contains just content elements. Additionally, it provides the best UX with dynamic interaction. In conclusion, users can simply access a single page in a better and more interactive manner.
2. Multi-Page Application
Multi-page apps are more in demand on the web. Nowadays organizations choose them in case their sites are very large. These solutions reload a website page for loading or sending data to/from a server through the users’ browsers.
3. Microservices Architecture
Microservices architecture concentrates on particular functions and single-page applications for quicker rollout and efficiency. Above all, it is easily developed with codes that provide the best quality to the application and can be flexible.
Microservices are the modules or small tasks that are built and then compiled for quicker application.
4. Serverless Architecture
Serverless architecture has no infrastructure or correlation associated with tasks. In this framework, developers can work on the third-party infrastructure rather than backend server handling, hence, making it simple for developers to implement the web app.
5. Progressive Web Applications (PWA)
These web-based solutions are made for working like native apps on mobile gadgets. Above all, they provide offline access, push notifications, and a chance for installing an application to your home screen.
Trends in Web Application Architecture
The two most popular trends in web application architecture are the following:
1. Client-Side Rendering
The prime difference between client-side rendering and server-side rendering is that when you visit a website that utilizes client-side rendering, just one request will be created to the server for loading the basic app skeleton. Then the content is produced dynamically utilizing JavaScript.
2. Server-Side Rendering
A request is sent to the server when you visit a site by clicking the URL. After the request is processed, the browser gets the JavaScript, CSS, and HTML files and the page content and finally renders it. Another request will be processed when the user decides to navigate to another page.
Features of Web Application Architecture
Here are some exclusive features of web application architecture:
1. Security
We all know about a web app’s vulnerability, which is why security becomes more important. Malicious code manipulation is the main concern. Hence, we should protect the app for keeping the data secure according to Government laws.
2. Scalability
Web apps’ horizontal scaling is another feature of the architecture. Similarly, it incorporates many regions and servers to handle the possible traffic or any type of fluctuation.
3. Extensible
Web app architecture’s lifespan is important for mobile app creators. On the other hand, the modern web application architecture should have a stable and long lifecycle.
4. Separation of Concerns
An application should be modular and self-contained in nature for components. Further, this helps developers solve problems and include features in the web app.
Moreover, the web app’s simplicity makes it an important part of the architecture that can be responsive, unique, fast, and fix issues. And there is analytics support, automated deployment, A/B testing.
Web Server Architecture and Its Types
Web servers play a pivotal in successful web app operation. Therefore, we must discuss web server architecture when it comes to describing the fundamentals of web application architecture. The servers are selected by performance indicators like app tiers, speed, storage, and processing power.
Here are the major types of web server architecture:
1. Java Web App Architecture
Java is a great programming language. This framework is the best for developing enterprise web app architecture according to the project’s complexity.
Java helps deliver the project with development solutions and the best expectations. Moreover, developers can utilize Java tools and frameworks that can easily work on complex apps.
2. Cloud-Based Web App Architecture
This architecture enhances the company parameters while working on server architecture.
In this architecture, the entire setup is built on the cloud that entails data separation for building a corollary. In conclusion, this architecture helps store the data on local servers or the cloud utilizing the cloud-based app functions.
3. Node.js Web App Architecture
Node.js is another aspect of the web server architecture that works on the web app’s model view aspect. This helps address code components with pattern development. It helps configure the components in the mobile web application without routing.
Moreover, to make sure the application runs smoothly, the entity-relationship helps process valuables, data systemization, and break modules’ logic.
We have covered the top reasons why you should invest in Node.js for your next web application development project in another article. Check it out for more details.
4. .NET Web App Architecture
