Typically a solid and a good practice for most of the entrepreneurs and business owners is to select the most appropriate system architecture for web application. At the same time, they should organise their ideas, such as app logic, features, functionality, business requirements, etc. A solid and correct application architecture in software engineering will determine the purpose of your product.

Regardless of how blurred the distinction between frontend and backend development has become, web applications require both. Let’s examine what are the different types of application architectures independently.

Application on a Single Page (SPAs)

Single-page applications, or SPAs, are designed to aid programmers in their work. A user does not need to load new pages each time they act on a website. Rather than that, customers can engage with it and receive updates to the current page’s content.

This style of web design architecture is developed so that it just demands the actual content and data. As a result, SPAs minimise disruptions to user activities, resulting in a more natural and dynamic user experience. By the way, the most frequently used programming language in this type of design is JavaScript.

Application Rendered on the Server (SSR)

SSR is the process of converting a Javascript framework-based client-side website to HTML and CSS on the server. With the use of this tool, it is possible to rapidly provide the most critical assets, thereby increasing the browser’s speed and reducing the time required to render the page to the user.

When creating an SSR application, the server compiles all the data and serves each request as a new HTML document. Once the browser receives the CSS, it can paint the UI without waiting for JavaScript to load. That is how the page gets rendered faster.


Microservices is one of the SOA architectures (service-oriented architecture). Microservices, in general, are small, lightweight services that perform a single function. That is a highly efficient and productive method of web architecture design. Developers can save a lot of time and money by utilising it.

Because the microservices components do not need to be written in the same programming language, they are not interconnected. That means that developers can use whichever technology they want, which speeds up and simplifies the creation of microservices web application architectures.

Architecture Without Servers

The name implies that a serverless application architecture overview is devoid of servers. That is not the case. Indeed, it indicates that deploying and operating management software-enabled servers is no longer necessary. However, third-party vendors sustain the entire infrastructure. A third-party vendor contributes the server and infrastructure management outsourcing.

In that case, the developer will consult with a chosen third-party cloud infrastructure provider to manage the infrastructure in the current online application architecture.

If you’re not enthusiastic about managing and supporting servers and hardware, serverless architecture is a godsend. This approach is advantageous because it allows you to launch the code while keeping the infrastructure intact.
