How to Design a Web Application Architecture: Components, Models and Types

Example of a serverless web app architecture.Client requests are routed to the app through an API gateway. While this one currently only allows direct requests to the home module of the app, in the future, it could allow for access to more components without going through the home module. Legacy monoliths are often migrated to this model to make use of its scalability and modularity benefits. However, managing apps built on such a model often requires seasoned developers, especially experience in DevOps and CI/CD. Apps made using this model are certainly more reliable than those with the previous model, as the presence of multiple web servers adds to the fault tolerance of the web app. However, since the database is still one common instance, it is the weakest link in the architecture and can be a source of failure.

  • You will receive quotes from qualified companies and will be able to hire the best candidate through a safe payment system.
  • Functions are stateless and can respond to different events – file uploads, API calls, updates.
  • The browser locates the URL and requests access by sending data from the server to the browser.
  • CDN or any server, that holds an already generated HTML page to be given to users upon request.
  • The business layer helps in processing the browser requests, performs the business logic of the requests, and shares the same back to the previous layer.
  • The web is a huge playground of a variety of applications, each designed in its own unique way.

Speaking of the business layer which is also referred to as the application layer, is a part of the app backend. The web app’s backend determines business logic and responses to browser requests that are sent to the presentation layer. It consists of the core application logic and outlines all internal flow for data and requests.

Node.js web application architecture

The auto loading facility dispenses with the need for special inclusion paths. As various components are developed in different coding languages, there is greater flexibility in choosing a technology of choice. Here are 8 of the most recognised architectural styles that have been applied in many popular structures around the globe.

What are the types of web application architecture

In 2021, 48% of users will be applying voice solutions for making search requests. What’s more, by 2023, 40% of entire user interactions will be fulfilled by using AI and machine learning. Most qualitative platforms with a modern web app architecture perform this process almost instantly, as no user wants to deal with time-consuming page loading. Thus, website application architecture comprises utter sub-components and external interchanges for the complete solution. Load balancing is another popular component of web application architecture. A load balancer is used to distribute HTTP requests between multiple identical web servers.

Data is stored in the cloud through cloud storage and is accessed online. Containers are a way of packaging up an application into a single file. They run the same way on any machine, and they can be shipped to different devices without worrying about compatibility. Containers are used by web applications and other types of software, including operating systems, databases, and even analytics tools like Splunk.

Multiple databases, multiple web server- I am the most reliable and efficient models of the three, as the web servers or the databases, none have a chance of failing the web application. One is to store identical data in all databases or evenly distribute it among the employee databases. However, there is a possibility of data crash which will lead to the destruction of the data.

When the user receives the info from the server, search results will be cached. SSR can’t handle heavy server requests, such as repeated HTML and CSS, hence the slow rendering when a full page is rebooted or the server is loaded. What’s more, interaction with the end-user is poor, and it’s impossible to create a full-fledged UI.

In other words, an Application Architect defines the framework for application-based solutions, then lays out a blueprint for implementing them. Apart from these, additional components like the database server will be sending the requested data to the server-side. The server always works for catching the request and sending it to the data storage for the page’s location and requesting for the data to get displayed on the browser.

Front-end Development:

So, enhanced scalability is nearly best practice web application architecture may be built with. As for microservices, this approach lets developers create a web app from a set of small services. The peculiarity of this web application architecture system architecture of web application lies in the absence of data storage. When a user provides a web server with data, it processes and saves it to the database, but its operation process happens outside the server.

What are the types of web application architecture

The server instance processes the request and calls any external APIs if needed. Web application architecture is, without a doubt, one of the most important parts of your web application. If you choose to develop your web app with a specific architecture in mind, you are certain to receive many benefits when it comes to maintaining and growing your application. To kick off the discussion, let’s start with the definition of web application architecture. In SPA dynamically loaded content is updated on the current page instead of loading new pages from the server.

Consider the Number of Users

The most important thing we need to notice here is the code which has been passed to the browser. This code may or may not have particular instructions telling the browser how to respond with respect to the different types of user inputs. That’s why a web application architecture includes all the sub-components and external applications interchanges for an entire software application. A web application architecture has to deal with the reliability, scalability, security, and robustness due to a large amount of global network traffic. Single Page Application architecture or SPA offers smoother app performance than websites and provides an interactive experience to the users.

That said, in this article, you would be getting the answer to what is web application architecture? You will also get access to highlights on the web application architecture layers, components, models and its types alongside the best practices for giving you enhanced results. Web app architecture basically represents relationships and interactions between such components as user interfaces, transaction processing monitors, databases, and others. The primary goal is to ensure that all elements work together correctly.

What are the types of web application architecture

So, two key components of a web application architecture are client-side and server-side. Under the client-side, we also mean front-end development and building UI/UX components that form the UI visual of an application . HTML, CSS, and JavaScript are technologies used for building the front-end of the application. Function-as-a-Service and Backend-as-a-Service are two types of serverless architectures. The former emphasizes more on events where it breaks the app into small functions that focus on code whereas the latter is more about frontend development tasks.

Progressive web apps or PWAs have been widely used in web app development for a very long time, but it is not going anywhere soon. Even though it runs on the browser, it provides users with the native mobile app experience. With a great conversion rate, user engagement, and less maintenance cost, one thing is sure progressive web applications will be a lasting trend in the industry.

Options of tech stack are limited when it comes to designing an isomorphic app. You only get to choose from a handful of JS-based libraries and frameworks. Web pages are generated in pure HTML, CSS, and JS; hence their performance is similar to that of apps built using vanilla JS. With the added ability of being installed on user devices , your users get a more uniform experience with your application.

But if your application is large or complex, then you should consider using a more complex architecture. The result is usually faster loading times and greater stability for your users’ experience with your site. For example, if you have an e-commerce site with 100,000 daily visitors and five web servers, you will want to make sure that each server is handling a similar number of users. If one server has 80% of the traffic while the others have 20%, it could cause performance issues or latency for the users on those other servers. You can use it to coordinate the execution of multiple AWS Lambda functions, for example, or to orchestrate the data flow between other AWS services.

The Design Phase

The amount of competition out there leaves little room for error. How can you ensure that you make the right choices in constructing your web-based application to create the best user experience possible? To answer these questions, it helps to know what web application architecture is so you can make an informed decision about how best to go about your project. According to the very basic web app architecture, a server, consisting of web page construction logic and business logic interacts with a client by sending out a complete HTML page. To see an update, the user needs to fully reload the page or, in other words, to have the client send a request for an HTML page to the server and load its entire code once again. Have a look at this type’s web application architecture diagram below.

What is the beauty of architecture?

These user interfaces don’t house a lot of your business logic since they’re exposed directly to your users. Apart from exposing an interface to users and handling their requests , there is another slightly less popular category of web app components. Jobs are often background services that are meant to complete tasks that are not time-sensitive or synchronous.

It connects to the business layer and, in addition to data retrieval, also manages data storage. Data is retrieved from the database servers by the data persistence layer. The different levels of web applications’ size and complexity all follow the same architectural structure, but their details are unique. In addition to learning how a request-response process functions and what components it includes, we’ll also cover how a simple request-response cycle works. When designing mobile-native applications, you can’t usually be certain of your users’ device specifications.

Definition of web application architecture

In this article, we’ll explain 3-tier application architecture, its layers and components, and the way all of this works. Web application architecture is the process of designing, constructing, and deploying a web application. Web applications are software applications that run in a browser. The browser is a client, and the server is the other end of the connection.

Design Patterns

This usually refers to back-end infrastructures such as cache server, database, and job queue. Besides, at least two servers, connected to the load balancer, process the user’s requests. The introduction was for overcoming the traditional limitations to achieve smooth performance. Besides, you can get an innovative and interactive user experience.
