Web applications have entered the list of essential elements of the Internet facilitating easy access to services and tools within web browsers. Generally, these applications are implemented on web servers are easy to access, and provide simplified interfaces.
On the other hand, cloud applications are the extension of web applications where they take advantage of the availability of almost unlimited resources in cloud computing. They contain additional features and, in general, support more operational and user requirements.
Currently, due to the continuing development of technology, both web and cloud applications provide various characteristics and opportunities. This blog is dedicated to the comparison of these two application models, placing an emphasis on issues like back-end structure, possibility to scale, and general architecture.
What are Web & Cloud Applications?
Web applications are specifically created to operate in the web browser – JavaScript, HTML, CSS, and sometimes backend languages such as Java, PHP, and Python.
These applications can be easily distinguished from traditional applications as they do not need to be downloaded on a user’s device; rather a URL can be used to open the application and it is run through the web browser.Â
Cloud applications are even closer to the concept of web-based applications, or rather, their further development. Although they also work on browsers, they can be implemented in mobile and desktop applications that interface with cloud services.
Ultimately, while both apps rely on internet access, cloud-based apps provide greater flexibility, scalability, and robustness, suitable for more complex tasks like enterprise resource planning or large-scale data processing.
Web-based apps are often more straightforward and suitable for basic functions that require less computational power and infrastructure.

How Do Web Applications Work?
Web applications primarily reside on web servers and are executed over the Internet. They are designed with a client-server architecture, which involves two main components: between the server side and the client side.
Here’s how they work:Â
Server Side (Back-end)Â
Traditionally the server side of a web application is the portion of the application that deals with matters relating to the server as a software entity including but not limited to database operations, business logic, and more. All these tasks are on the server side of the web application, and their proper functioning is the responsibility of the server-side code.Â
Database Interactions: It is here that the data retrieval and storage with the help of database operations occur on the server side. This interaction is critical for dynamic content and user-specific information.Â
Business Logic: Business rules and logic of the application are executed on the server side and the user interface is coded by the client side. These include user-input processing, generating and using mathematical authentication tokens, and more.Â
Processing Requests: Whenever a user makes a request (for instance by following a hyperlink or submitting a form), the server responds to such a request and then processes that request, and a response is then sent. This response can be in a format like HTML formatted JSON data or any other form of data.Â
Client Side (Front-end)Â
Client-side in reference to a web application refers to the part of the code that will be interpreted by the client or the user’s web browser. This particular code is used to closely interface with the user, that is, to display the graphical user interface and manage the user’s inputs.Â
Rendering: About programming, when a user opens a web application, the browser takes HTML, CSS, and JavaScript files, and shows them. It includes the activity of presenting textual content, graphics, ActiveX buttons, and all other graphical objects.Â
User Interaction: End-user scripts, normally in JS, deal with functionalities such as submission of forms, click on buttons among other functions, or changes in portions of an HTML page. This script improves the usability by offering feedback as well as other things, which are in the following points.Â
Data Fetching: As for the client-side code, there are ways to download data from a server asynchronously for an ‘X’ amount of time, such as AJAX (Asynchronous JavaScript and XML). This makes it possible for the web application to refresh/reload every part of the page instead of the entire page.Â
How Does It Work Together?
User Request: A user accesses a web application by entering a URL in the browser or clicking a link.
Client Request: The browser sends an HTTP request to the web server hosting the application.
Server Processing: The web server receives the request and processes it using the server-side code. This may involve querying the database, processing business logic, and preparing the response.
Server Response: The server sends the response back to the browser. This response contains the HTML, CSS, and JavaScript needed to display the page.
Client Rendering: The browser receives the response and renders the page. Client-side scripts enhance the functionality and interactivity of the page.
User Interaction: The user interacts with the web application. Client-side scripts handle these interactions and may send additional requests to the server as needed.
Data Exchange: If further data is needed (e.g., form submission or dynamic content update), the client-side code sends asynchronous requests to the server, and the server processes these requests and sends back the required data.
This continuous interaction between the client-side and server-side components enables web applications to provide a seamless and responsive user experience.
