Which architecture is better suited for web    applications & Why?


Web application architecture defines the relationship between web application components (i.e., databases, user interfaces, and middleware platforms) and how they interact. Well-designed web application architecture makes sure that your entire system is in sync and provides an important foundation for further expansion of the application in subsequent phases of development.

What is the web application architecture function?

Two sub-programs or code sets are typical for every web application: client- and server-side. The two programs operate separately and simultaneously but with the common purpose of providing seamless web experiences for users.

The server-side software code lives on the server. It responds to HTTP requests.

When designing a web application, the programmer is responsible for deciding what code to put on the server and what the code will do about the client code. The server-side code is responsible for generating any page that is requested by users as well as storing different types of information such as users’ profiles as well as inputs.

However, the client-side code is communicated via HTTP requests and does not access the server’s files direct. Instead, it’s parsed by the browser that responds to user input. In contrast to server-side codes that are client-side, the code can be edited and reviewed by the user. It is a mix of HTML, CSS, and JavaScript used to create pages and web content.

Types of web-based application Architecture:

The most popular kinds of web architectures, and examples of each, are listed below:

1. Single Page Applications (SPAs):

SPA structure is designed so that only a small portion of the page’s content is updated each time the user is moved to a different page. Therefore there is no need to refresh the same elements. This makes it practical for users and developers! 

2. Multi-Page Applications:

Multi-Page applications are quite popular online because all web-based applications utilized MPA technology in earlier times. This type of architecture reloads pages on the web to send information from or to the server via the user’s browser. App Development London usually choose MPA architecture if their application is quite large.

Amazon, as well as eBay, are among the most popular multi-page websites in the world today.

3. Micro services:

Micro services are a type of service-oriented design (SOA) that is used to create distributed systems of software. In this type of design, UK app developers create web applications using a set of services that are loosely coupled and can be used independently. This functionality is made easier to create, expand and grow an application.

A few well-known Micro services architecture projects include Netflix, Uber, Spotify, and PayPal.

4. Server less architectures:

With this kind of design, developers do not require the configuration or management of servers with server management software. However, that doesn’t necessarily mean there’s a lack of servers. Third-party cloud providers such as Amazon and Microsoft provide virtual servers that can dynamically manage the allocation of resources to machines.

5. RAD Stack:

RAD stack allows developers to build apps of all sizes and deploy them in crucial situations. In addition, it’s the default stack of Crowdbotics Builder! 

Weaknesses and strengths of the various application architectures:

1. Single Page Applicant (SPA):


  • Performance that is super fast compared to traditional architectures
  • Great functionality on desktops as well as mobile devices.
  • Increased flexibility and responsiveness because there’s no need to load or re-refresh websites
  • Optimized and simplified development


  • A load of heavy browsers
  • They need high security for data because of the use of Cross-site scripting (XSS) that allows hackers to access the code on the client side and possibly add harmful scripts.

2. Multi-Page Applications (MPA):


  • Multi-faceted functionality, such as MPAs, enables the integration of multiple features, all while still maintaining an easy-to-use user interface.
  • The highest SEO optimization can be accomplished through multi-page applications as they permit the dispersion of keywords across different pages. This is not the case with SPAs which could cause a mess on just one page.


  • There is a lot of complexity involved in backend development. MPAs are heavily dependent on server-side programming and this means that developers need to spend more time working on developing backends.
  • Performance and speed are low. MPAs are much heavier than SPAs. This leads to slower loading speeds and lower responsiveness.
  • Debugging is complex as app development UK agencies have to verify every GUI (Graphical User Interface) and the relationships of every page to make sure there aren’t any broken requests.

3. Micro services:


  • A clearly defined division of the program by modules allows you to be aware of how every component of the code functions and adds new features easily.
  • Scalability is high. Apps Developers UK can create additional services at any time of development without changing the entire architecture.
  • It is easy to deploy compared to other architectures because services are not dependent on one another.


  • The complexity of the process
  • Support issues because each micro service must be managed separately that requires continuous or automated monitoring

4. Server less Architectures:


  • Lower cloud costs
  • Cost reduction for development
  • High Capacity
  • Faster release
  • Mechanisms for registration and control that are integrated


  • Limitation of resources such as memory, runtime throughput, CPU utilization
  • Security concerns arise from many applications that run on the same platform

5. RAD Stack:


  • Highly adaptable and flexible to changes
  • Because of code generators and reuse of code, There’s less requirement for manual code coding.
  • Utilizing code generators and code that is reused will mean that you don’t need an enormous amount of resources to accomplish your tasks. 
  • Using intermediate code, scripts, and abstractions at a high level makes it easier to send deliverables.

Its weaknesses:

RAD projects could be a failure if developers aren’t determined to deliver software on the deadline

Highly skilled developers or designers

Best Practices and Trends in the web application architecture:

Technology is evolving rapidly and so do web architecture for applications. One trend that you’ll notice is the usage of a service-oriented architecture. In this type of architecture, the majority of the code that runs the application remains in service and each service comes with an individual HTTP API. This allows a particular code segment to send requests to another section of code running on an entirely different server.

  • Another important trend we’ve discussed before is single-page apps. The user interface of this application is provided by the rich JavaScript application that is accessible to the user’s browser across many interactions. 
  • With the abovementioned changes, web apps have become advanced and can provide an optimal experience on various devices and platforms. While most of the code that makes up the application is the same, it can still be enjoyed on smaller screen sizes.
  • To provide your users with a pleasant experience on the internet, You must go far beyond running a functioning web application. These are the top ways to ensure you be aware of the following:
  • Consistency: Your chosen system should offer the same approach to solving all your development issues. You should also examine the requirements of your application to choose an approach that will meet the majority of your goals for development.
  • Speedy performance: Examine the best web applications in the market, and measure their speed on the web and their responsiveness to establish guidelines for your application.
  • Simple: If you can develop your application using a minimal structure, choose the most straightforward option. While it’s important to think about the possibility of scaling options but there’s no need to complicate things in the beginning.
  • Self-maintenance: The application’s architecture will be able to detect problems and fix them by itself.
  • Automation Automate the development testing, deployment, and testing as you can. Data management that is easy and error-free Think about your data’s storage and processing procedures and select the most efficient methods to manage your databases without incurring unnecessary expenses.


Application architecture is the base of web-based application development. Whichever architecture you choose is the basis for all the subsequent elements of the application’s logic and the interplay between its elements, as well as the functions. This is why it is crucial to recognize the unique characteristics of each type of architecture and pick the appropriate one before you begin developing your application.
