Fundamentals Of Web Application Architecture



It describes the high-level internal structure of the software system and outlines the ways major parts of it are wired together. Appvneturez makes sure to keep the essential parameters in while developing the web app and including vital factors to it. So, if you are planning to develop the web app and need any guidance with its architecture then feel free to contact us. When we talk about trends, there are mainly two trends in the web app architecture that are counted as a priority. Let us give you an insight into it to give a glimpse into the web app architecture world. The Client or Web Browser is the one in which the users can interact with the web apps using the functions. To give you a better understanding of it, here is a small working of web application architecture that can explain it all.

  • HTML5 introduced explicit language support for making applications that are loaded as web pages, but can store data locally and continue to function while offline.
  • Of course, it is designed to function efficiently while meeting its specific needs and goals.
  • HTML, CSS & Javascript are used for writing client-side code, these codes can be seen by the user and it responds to user input.
  • To build a web application, you can start with an experienced freelance developer who will help you architect your project.

Moreover, you can use cloud servers to execute some of your operations. Modern web architecture should be as flexible as possible to allow you to easily and quickly adapt your product to the needs of the market and the expectations of your users. Moreover, if you are planning to launch an international project, the number of users of which can grow exponentially, the microservice model will be a safe option. It enables you to add new components to the system and fix any bugs without shutting everything down. Full webpage reloading takes time and degrades the user experience.


The goal of the UI and UX web application architecture components is to design a perfect user experience. At the same time, structural components are more about the smooth running of the web app and its features. You can use a web application model that consists of one server and one database, or you can design an application that operates on multiple servers and databases. The second approach is considered to be more sustainable and reliable. Despite the huge flexibility provided by the Java ecosystem, it isn’t uncommon to see projects with the Monolithic Architecture type face issues. Monoliths cause that business logic, various tests, and web resources, including templates, images, etc packed in a single unit and deployed to the server.

From the business aspect, a web application should stay aligned with its product/market fit. From a software engineer’s perspective, a web application should be scalable, functional, and able to withstand high traffic loads. The server side alone has to support many desktop and mobile browsers, be integrated with APIs, accommodate a lot of functionality, and connect to a database. Another major trend that we’ve already touched on are single-page applications. The UI of this web application is delivered via a rich JavaScript application, and it resides in the user’s browser over various interactions. It also uses AJAX or web sockets to make asynchronous/synchronous requests to the web server, eliminating the need to refresh the pages. This offers a more robust experience for users thanks to limited page loads and interruptions.

Controller The controller module acts as an interface between view and model. It intercepts all the requests i.e. receives input and commands to Model / View to change accordingly. The MVC design pattern consists of three modules model, view and controller. Utilize proper security initiatives to reduce the chances of malicious penetrations. Web server facilitates website traffic, which is not very resource-intensive.

This basically comprises The web browser or client, The web application server and The database server. With mobile becoming the preferred device for search, the need is for Web app development and architecture that meets requirements across all platforms. To put it quite simply, modern web app architecture includes various components and external apps.

SSR is the process of rendering a client-side Javascript framework website to HTML and CSS on the server. With the help of this tool, it’s possible to quickly deliver the most important assets, thus accelerating the browser’s speed rendering the page to the user takes less time. Single-Page applications or SPAs aim to facilitate programmers’ work. To make an action on a website, a user has no need to load completely new pages every time. Instead, they can interact with it receiving updated content to the current page. With a software architecture, it comes easier to see the big picture. The central aim of it is to identify both functional and quality requirements and handle them to improve the overall quality of an application.

Writing every feature in a single codebase would take no time in becoming a mess. A typical social networking application has various components such as messaging, real-time chat, LIVE video streaming, image uploads, Like, Share feature etc.

Web Application Architecture: Components, Types, Best Practices

Not to mention, by supporting horizontal and vertical growth, software deployment is much more efficient, user-friendly and reliable. As technology continues to evolve, so does web application architecture. One such trend is the use of and creation of service-oriented architecture.

For example, the client data would be accessed by calling a “list_clients()” function instead of making an SQL query directly against the client table on the database. This allows the underlying database to be replaced without making any change to the other tiers.

So, in such a failure, all the requests will automatically go to the new server, without affecting the web app’s functioning. However, if something happens to the database, the app will crash.

Since SPAs move the logic to the client-side, they have to be written using client-side scripting. This significantly reduces the server load, as opposed to server-side scripting. Along with its many frameworks, this language allows creation of both small and robust applications.

For example, the web interface can be changed to a console one without changing the business rules. When it comes to security, this web application architecture provides identity management and accessibility to secure app data. Structural Components – These components include the database server and web application server. To create them a good knowledge of CSS, HTML, JavaScript, as well as .NET, Java, Ruby, PHP, and Python is required. Single-page Web App Architecture – Here, a user simply needs to request the page. Instead of switching data in JSON, this kind of architecture depends on server requests in HTML or JavaScript.

Not only this, but it also helps in determining the progressive web apps future since it helps in showcasing what the app will look like. It is one of the most used mobile app architecture best practices in the past.However, it has its own issue, if the server is down, then the model will be down as well. For the web apps, now this model is not ideally used due to its limitation of one server. The model depends upon the web application architecture and database management trends.

All the web applications run on the client-side and the server-side. When a user makes a request there are mainly two programs run on both sides. Some of the beneficial features of the .NET framework are less coding and increased reuse of code, deployment, reliability, and integration with legacy systems.

Developers prefer this programming language as it is concise, easy to understand, and good for maintenance. Furthermore, Python is also suitable for newbies whether this is their time using Python or the first time they work on a certain project. This practice allows us to combine various Java frameworks or tools to develop the web app no matter how complex or simple it is. Thanks to this characteristic, it is preferred to use in multitier projects or in the enterprise development environment.

The server-side code is also responsible for creating any page requested by users as well as storing various types of data like user profiles and inputs. At the same time, if your task is just layout and animation of landing pages, then there is simply no room for Clean Architecture. However, it can serve as an excellent springboard for explosive growth of the application. Web development has come a long way, from simple JQuery scripting to the development of large SPA applications. And now web applications have become so large that the amount of business logic has become comparable or even superior to server, desktop and mobile applications. We would like to share an approach that we have been using for many years in applications development, including web applications.

The user’s web browser is the client tier component, as it accesses the rest of the application through the web tier. The serverless architecture uses servers to run a web application. The team outsourced server management and maintenance to a third-party vendor. Applications are developed as a set of functions, which are later connected to form a single application. Usually, add-ons are used for GPS, payment processing, camera, microphone, etc. The usage of APIs allows developers to expand the functionality of their web applications without having to write these features from scratch. The natural consequence is shortened development time and decreased budget of the project.

Progressive web apps can run offline, send push notifications to users, and interact with your hardware’s APIs.
