A web application refers to application software hosted on a server and accessible via a web browser.
, Unlike traditional Software, a web application user does not need to install it on their computer. All they need to do is log into the application using their favorite browser. The current trend is to provide a user experience, and functionality equivalent to Software installed directly on computers. The technologies used to develop web applications are the same as those used in the creation of websites.
Cloud computing is therefore this rapidly expanding phenomenon that aims to evolve the traditional software model towards the Internet and mobile telephony is integrated as an extension of use to this model.

Usually, a potential user is used to purchasing Software and installing it on their computer. In a coherent logic of profitability, the software publisher will plan to offer many features to appeal to the widest possible audience. Therefore, the user will end up with a solution of which he will ultimately use only a tiny part.
The web application is approached differently. Indeed, the cost of tailor-made development for creating a web application is very affordable; the user can call on a web agency to develop a solution specifically adapted to his needs. Once developed, the solution will only offer the functionalities that users need and can easily evolve according to new needs.
The examples of web applications are of course endless. Each professional may have specific needs. As an example, we could cite:
reservation management for a hotel an online billing application for a business or merchant a patient file management tool for a doctor etc
The advantages of the web application
Today and more and more, it is possible to subscribe to web applications. The Internet user then pays monthly for his access to the online service. This is the so-called SAAS business model.
We can therefore summarize the main advantages of a web application as follows:
CONTROL OF YOUR BUDGET AND COST REDUCTION
the starting bet is non-existent no upgrade of your infrastructure the budget is predictable by a fixed monthly subscription investment spread over time you only pay for the features you use billing is proportional to your actual consumption adaptation, maintenance and improvement costs are included you save on computer equipment
implementation and deployment is faster (you sign up and everything is installed) circulation and sharing of data between users are optimized you avoid solicitations from IT staff more intuitive and easier use of applications
universal access from any type of workstation: PC, laptops, mobile phones, tablets, etc. no operating system incompatibility (all you need is a browser) you can work from anywhere on the planet your data is centralized your data is available 24/7
BETTER SAFETY MANAGEMENT
you benefit from the resources of large data center infrastructures your access to data is controlled by identification and certificates automatic backups hosting of your data in a contractual confidentiality framework
CONTINUOUS EVOLUTION AND INNOVATION
you always get the most recent version no risk of obsolescence application upgrades are automatic and transparent your experience feedback is directly taken into account for permanent improvements and innovations you reduce electricity consumption by promoting the pooling of resources on the same servers

In client-server technology, used for the World Wide Web, the Web browser sends requests for Web pages to the server. The server responds to requests by sending the pages to the web browser. The browser then displays the pages to the user.
Web applications use this technique to implement their graphical interface. This is made up of pages created from scratch by the Software during each request. Each hyperlink contained in the page causes a new request, which will result in a new page. Unlike a static website where the pages are previously saved files.
Web pages contain various widgets such as push buttons, icons and text boxes, allowing manipulation of the application. Each operation of a push button causes a new request to be sent. Web pages can contain applets.
, Unlike other Software, a web application installed on a server is immediately usable by the consumer without purchasing and installing on his computer, as long as the consumer’s computer is equipped with a browser. Web and network connection. This avoids interventions by system administrators, interventions which are often more expensive than the Software itself3.
The web application is often made available to the consumer by the software publisher on its servers3 – a technique called Software as a Service.
The use of the web browser as a client part – software that is available on many operating systems – ensures the portability of a web application.
