How to choose the right technology combination to create your web application ?


Whatever the software is, the technique used during its development has an impact on its performance. So, before writing a single line of code whether for a web application or a mobile one, it is necessary to determine the best technology stack. However, this is not always obvious and it is a determining element that can make the success or failure of your business. These are the technological possibilities that your idea of a web application needs. The possibilities offered are indeed numerous. Opting for the wrong language or the wrong framework could have serious consequences. We define below the concept of technology stack and how it can be used in the context of the implementation of an online application. We also present the different models of technology stack, their use and the factors that determine the right choice.

What is the definition of a technology stack ?

Let’s start from the beginning: What is meant by technology stack Or Tech Stack ?

The term « Technology Stack » refers to a series of technological strategies. Used in order to develop a web or a mobile application : a front-end, a back-end and a database. This refers to the different development languages, frameworks, libraries, patterns, servers, user/UX interfaces, software and instruments that designers use to realize web and mobile apps. The concept of the technology stack stems from the fact that several layers are superimposed when designing a web app. These different strata require the use of programming codes; distinct hardware components and elements which constitute a stack of various technologies.


The frontend corresponds to what authorizes a user to communicate with the system. Its main objective is to guarantee accessibility ease of handling, a user-friendly interface, a call to action and operations. It is important to know that several instruments and languages can be used for the design of the front-end. They are all related to the combination of HTML in order to generate and insert CSS content, so as to materialize and represent the JavaScript contents to allow interactivity on web pages.

HTML (HyperText MarkupLanguage) to generate and place the information.The Positioning and ordering of page elements are done through this language.

(CSS) Cascading Style Sheets are mainly used to apply letters, colours, layout characteristics, background content, etc.

JavaScript is used in browsers in order to support the interactivity of web pages. There are many JavaScript libraries. which are essential to integrate powerful features into your workspace. This includes jQuery, Bootstrap et Slick, integrated into tools such as Angular, Vue.js and React. In addition to HTML CSS and JavaScript, there are many other frameworks based on JavaScript.

Backend (server side)
The backend, also known as development server side is considered to be an internet application operating mechanism. This is the responsible component. This is the component responsible for responding to user actions, such as having access to a database and the execution of design operations, reading, upgrading and deleting.
Every component of the application can understand how and when to respond to user requests. This part of the application is not accessible to the user. It works behind the scenes and allows the front end to do its job. Backend design for internet apps consists of three parts: programming languages, databases and a server.

Programming languages Many development languages and frameworks are available for server-side web design.

Among these languages, the most common are :

  • JavaScript (NodeJS, MeteorJS, ExpressJS)
  • Python (Django, Flacon)
  • PHP (Laravel, CodeIgniter)
  • Ruby (Ruby on Rails)
  • Scala(game)

Databases: An internet application which does not have a database will have limited functionality. Nowadays, almost all internet apps require entering the person’s contact details as well as certain other necessary information.
The database is needed to store this data.

There are two kinds of databases: relational and non-relational.
The most common are:

  • MySQL (relational)
  • PostgreSQL (relational)
  • MongoDB (non-relational, document))

Server: The technology stack for web app design must include an application hosting server. This is where customer requests are received and processed.
Two servers in particular are most often used for web apps:

  • Nginx
  • Apache

Middleware: The middleware is the hidden stratum that connects the client side and the server side. It is not just a design tool. It includes application servers, web servers, CMS and other related items. This layer combines at least two frameworks, applications or components. To facilitate connection between client side and server side. The role that the middleware layer plays is essential in the process of distributing operations performed in real time, that goes beyond sending requests and responses to client and server.


How to choose the technology stack most suitable for your web application ?

Creating a web application, involves the use of a combination of technologies like:
The frameworks, the servers, the language, etc. which can work together in order to guarantee its proper functioning of the application. In order to be able to select the most appropriate technology stack for a web application, there are some key criteria to consider
Platform Kind: Before proceeding with the selection of Tech Stack for your web application, it is essential to be aware of what you expect from the project. First, identify the target audience, determine how it should use the application when and where. The answers to all these questions will allow you to decide if you need a unique solution or multi platform to choose the best technology stack to use. Even within projects of similar kind, the technology stacks you need may be different.

Project requirements: The choice of the technology stack basically depends on the problem you want to solve. Before you get carried away with choosing your technology stack,, you have to assess whether it is essential or not. For instance, if your project is small, you don’t need a big technology stack. Small-scale projects are usually faster to complete and do not necessarily require advanced tools and frameworks. On the other hand, the medium sized projects require a more important level of technological involvement. However, in case you plan to make a complex app to manage a complex process. The establishment of a robust technology stack is necessary. You may need a combination of different languages and development frameworks. It should be mentioned here that the dimension of your web application to be worked out depends on the requirements of the users.

Expertise: By choosing your technology stack, be sure to hire people with the required expertise so as not to waste time learning a new framework, language ou tool. In the event that you are determined to make your application work on a specific technology stack you can always hire new programmers for this purpose.

Scalability requirements: The role of technology stack in the possibility of a further development of an application, is to provide for an increase in the number of users and functionalities. Your web application should be scalable. To this end, the Tech Stack you employ must be able to scale sufficiently and be able to adapt to future changes. If you plan to invest in a new web project, opt for a scalable Tech Stack with flexible programming languages and various libraries and structures.
Tech Stack scalability can be :
Either vertical by adding new features to your app
Or horizontal by adding more physical machines or management units to your server.
Horizontal and vertical sizing protects protect your application against crashes.
Security: When setting up the technology stack for your web application, it is essential to ensure the protection of the application. Choose technological solutions offering a high level of protection, before starting the design process. Examine the degree of vulnerability of a programming language and see how it performs. This is essential, especially if your business processes a large number of online payments.

Switch-on delay: Development timeline is another determining factor. When choosing your tech stack, Some technologies tend to reduce development time, while others slow things down for your development. It is often recommended to consider out-of-the-box solutions for your technology stack which give access to a set of basic libraries…It is possible afterwards to add functionalities to your application through third-party integrations and to avoid writing the code from scratch.
This speeds up the development process. In addition, well-documented technologies can greatly facilitate the development of certain functionalities.
Maintenance: Your development team must be able to maintain the web application after its start. At this stage, the choice of technology stack can be motivated by two existing factors if you want feasible maintenance :
Lines of code
Your code should be short, simple, and easy to maintain. It helps developers spend a short time trying to review, debug and process codes.
Software architecture
Your choice of technology stack must be guided by your software architecture. Based on this, you should consider technologies that enable both static and dynamic component configurations. It makes the application performance transparent, even when the number of users increases or when you add more attractive features …

Some examples of technology stack

There are certain technology stack that offer a ready-to-use combination of tools to develop your web application

LAMP: LAMP (Linux, Apache, MySQL, PHP) is one of the most popular back-end technology for Web development.

  • Linux : Operating system,
  • Apache : Web server,
  • MySQL : database.
  • PHP : programming language

This technology stack is the most popular with developers for its security, flexibility and customization options.
Python-Django: The technology stack Python-Django is based on the python language and uses Django. Framework. The server used is Apache and the database is MySQL. This is an ideal choice when you want to create a fast web application
MEAN: MEAN (MongoDB, Express.js, Angular, Node.js) is used for full-stack development of Web applications. JavaScript is the programming language used for the front-end and back-end development.

This technology stack is recommended for building high-performance and scalable web applications.

  • MongoDB : database
  • Express.js : application framework
  • Angular : front frame
  • Node.js : operating environment..

MERN: MERN (MongoDB, Express.js, React/Redux, Node.js) is a popular choice for creating a responsive single-page application and large web applications .
This technology stack uses ReactJS for front-end development and NodeJS for back-end development.



Different Web applications require differents development tools. Choosing the right technology stack for web application development requires an in-depth knowledge of each of the technologies involved.
