Web applications are tools or programs that enable communication between businesses and their users. With widespread cloud adoption and changing work protocols, web applications that can are delivered as Software as a Service (SaaS) are more in demand than ever. Understanding what they are and how these apps function can help professionals choose the right solution for them. So, let's get right to it.

What are Web Applications?

In simple terms, web applications are programs or tools that can perform functions with the help of a web browser. These apps share a client-server environment where the client or user inputs information and the provider stores and processes the data.

From a simple website contact form to emails, spreadsheets, photo/video editing tools, and file-sharing tools, web applications and SaaS can take many forms. Most businesses are now operating with a mix of internet-based transactions, and web applications play a crucial role within such a structure. SaaS applications are also vital in facilitating collaboration. Thus, intra and inter-organizational operations are heavily dependent on them too.

Significant Advantages of SaaS Apps

Web applications come with many benefits to both businesses and their users. Some of these advantages are:

  • No hardware or software installation is required. Apps can be used over an internet browser.
  • Requires lower technical requirements from the user
  • Faster maintenance and upgrades
  • Accessibility and compatibility across multiple devices and operating systems
  • Allows collaboration on the same files at the same time
  • Reduces software piracy and security threats

How Do Web Applications Work?

As mentioned, web applications, especially SaaS, work through web browsers. They require three major components - web servers to handle requests from the client, app servers to execute the input, and data servers to store the information. Often, the server-side and client-side programming are done in different programming languages and are integrated to form user-friendly interfaces for the parties involved. Here is a look at the steps involved in the function of web apps.

  1. User creates requests through the app's interface
  2. The request is sent to the app server
  3. App server executes the request sends the processed data to the web server
  4. The user gets the processed request on their interface from the web server.
