Web Application Architecture Explained

It is not surprising that businesses want to establish an online presence. One way to do this is to make your website. With the correct strategies in place, your website communicates with your potential customers 24/7. It helps you attract, appeal, and sell your product or service.

For a website to perform all these essential business functions, it must be robust, reliable, and safe. Web app development process helps you create an effective information system. In this article, we will help you understand web application architecture, its components, the best practices and trends, and how to proceed with a web app development.

What Is Web Application Architecture?

A website is composed of the backend, frontend interface, databases middleware systems, etc. Web application architecture is a layout that explains and articulates how these different components interact with each other. So, if you have a complex website, web application, mobile application, the architecture will ensure the smooth functioning of several features simultaneously.

Opening a webpage without any hitches requires an efficient architecture in place. When a user opens a webpage, the server sends the request to the browser. More often than not, the request is for web documents (PDF, HTML, etc.). With a robust architecture in place, this information retrieval will happen quickly without any hassle. Thus, architecture is crucial for the simple as well as complex functions of your website. Understanding it will help you navigate problems on your website.

Web Application Architecture Components

#1 DNS

DNS is the digital-analog for phonebooks. Like phonebooks had people's numbers and names, DNS or Domain Name System has domain names and IP addresses.

#2 Load Balancer

A load balancer prevents overcharging of servers. Web application servers mirror each other and have multiple copies. Thus, when a user asks for information, the load balancer distributes the task to enable smooth functioning by preventing overcharging.

#3 Web App Servers

When a user requests a document, it is web app servers that help fulfill that request. The web server refers to request backend infrastructures to process the request.

#4 Databases

The database stores information in an organized manner. When a user searches for a query, the server will retrieve information from the database.

#5 Caching Service

Have you ever noticed how fast a webpage reloads when you have visited it in the past? It's because of the caching services. The cache stores the user query and the data the user clicks. It makes the computation of a similar question faster.

#6 Services

For an efficient user experience, developers create different services in the form of separate apps. It occurs when the web application is on a specific level.

#7 Data Warehouse

A data warehouse is an essential part of any web application. It is a model of storage and exchange of data. It can store data in the form of videos, photos, etc.

#8 CDN

Content Delivery System delivers content on the last server globally to let people load data from different sources.

The Best Practices and Trends In Web Application Architecture

Now that we understand each architecture component briefly, a vital question to consider is the ideal architecture. How can one make their website's or application's architecture top-notch? Because if it is top-notch, then testing, debugging, modification, etc., is effortless.

Here are a few features that your architecture must have to perform well:

With well-structured and understandable code helps any developer solve problems in the code.

The code should be reusable because it would be a waste of time and resources to develop a new set of codes for a new website.

It should be efficient.

It should use go-to security standards to prevent any breaches or attacks on the database of your website.

Every code has problems. Thus, the code for architecture should be flexible for any changes.

Testing is a vital part of any process of web app development. Thus, the code should be easily testable.

Solves problems consistently and successfully to prevent any future hassle.

Scalable in the development process, so if you ever want to expand, you don't have to start from scratch or make any significant changes.

Wrapping Up

For an efficient and reliable web application architecture, an experienced web development company is essential. Outsourcing is a popular trend among businesses because it's convenient and cost-effective. Their years of experience provide the best web development service possible.

The benefits of a stellar architecture are immense in terms of security and user experience. We hope the blog was informative and helped you understand web application architecture and its related components and best practices.
