They achieve this by using JavaScript frameworks or libraries to handle client-side rendering and data manipulation. SPAs are commonly used for applications that require real-time updates and interactive user interfaces, such as social media platforms, messaging apps, and collaborative tools.

3. Microservices Architecture

Microservices architecture is an approach to building web applications as a collection of small, independent services that communicate with each other through APIs. Each microservice is responsible for performing a specific function and can be developed and deployed independently. This architecture promotes modularity, scalability, and fault tolerance, as each microservice can be scaled independently and can fail without affecting the entire application. Microservices architecture is commonly adopted in large-scale applications with complex functionalities and high traffic volumes.

4. Serverless Architecture

Serverless architecture, also known as Function as a Service (FaaS), is a cloud computing model that allows developers to build and run applications without the need to manage servers or infrastructure. In serverless architecture, developers focus solely on writing the business logic of their application in the form of functions, which are executed in response to specific events. This architecture offers scalability, cost-efficiency, and faster time-to-market, as developers can focus on writing code rather than managing servers. Serverless architecture is particularly suitable for applications with unpredictable workloads and event-driven functionalities.

These are just a few examples of the various types of web application architecture available. Each architecture type has its own strengths and weaknesses, and the choice of architecture depends on factors such as the nature of the application, scalability requirements, development team expertise, and budget. By understanding the different types of web application architecture, developers can make informed decisions and adopt the architecture that best suits their needs.

Renditions of Web Application Architecture

When it comes to web application architecture, there are two main renditions that developers can choose from: server-side rendering (SSR) and client-side rendering (CSR). Each rendition has its own advantages and considerations, allowing developers to tailor their approach based on the specific needs of their web application.

In server-side rendering (SSR), the web application is rendered on the server before being sent to the client’s browser. This means that the initial loading time of the web app is faster, as the server pre-generates the HTML content. However, subsequent interactions may be slower, as each interaction requires a round-trip to the server for rendering.

On the other hand, client-side rendering (CSR) involves rendering the web application on the client’s side using JavaScript. This allows for faster subsequent interactions, as the server only needs to send the necessary data to the client instead of rendering the entire page. However, the initial loading time may be slower, as the client needs to download and execute the JavaScript code.

“The choice between SSR and CSR depends on several factors, including the complexity of the web application, the desired user experience, and the target devices.”

In summary, the decision between server-side rendering and client-side rendering plays a crucial role in determining the performance and user experience of a web application. By carefully considering the specific requirements of the project, developers can choose the rendition that best aligns with their goals and delivers an optimal user experience.

Note: The table below provides a comparison between server-side rendering (SSR) and client-side rendering (CSR) in terms of performance, initial loading time, subsequent interactions, and search engine optimization (SEO) considerations:

	Server-side Rendering (SSR)	Client-side Rendering (CSR)
Performance	Fast initial loading time, slower subsequent interactions	Slower initial loading time, faster subsequent interactions
Initial Loading Time	Fast	Slow
Subsequent Interactions	Slower	Faster
SEO Considerations	Good for SEO, as the server generates HTML content	May require additional optimizations for SEO, as content is rendered dynamically on the client

Web Server vs. App Server Architecture

When it comes to web application architecture, it’s crucial to understand the difference between a web server and an app server. These two components play distinct roles in the functioning of a web-based application.

A web server is responsible for handling HTTP requests from clients, such as browsers, and serving the requested web pages or resources. It processes static content like HTML, CSS, and images. The web server acts as the intermediary between the client and the server-side scripts running on the app server.

On the other hand, an app server handles the dynamic processing of web applications. It executes server-side scripts, accesses databases, and generates dynamic content. The app server interacts with the web server to fulfill client requests and deliver the requested web app functionalities. In simple terms, the web server focuses on delivering static content, while the app server deals with the dynamic aspects of the web application.

Key Differences between Web Server and App Server Architecture:

Web Server	App Server
Handles HTTP requests from clients	Executes server-side scripts and processes dynamic content
Serves static content like HTML, CSS, and images	Interacts with databases and generates dynamic content
Acts as an intermediary between the client and the app server	Fulfills client requests and delivers web app functionalities

Understanding the distinction between web servers and app servers is crucial for building efficient and scalable web-based applications. Both components work together to provide a complete web application experience to users, with the web server handling static content delivery and the app server managing dynamic processing.

The image above provides a visual representation of the web server and app server architecture.

By comprehending the roles and functionalities of web servers and app servers, developers can design and optimize their web application architecture effectively. This understanding allows for better scalability, security, and performance, leading to an enhanced user experience and the successful execution of complex web applications.
