What is SaaS in cloud computing?
Software as a Service or SaaS in cloud computing is just a technical term for the software or applications we are using online. We all know about Netflix, Amazon Prime, Semrush, Ahref, Gmail, Google Drive, etc. These applications and many more are examples of SaaS because they offer software to end-users over the internet.
In SaaS, All the resources are controlled by the vendor, and end-users use the application on a subscription basis. The SaaS cloud services are easy to use as we don’t need to install them on our PC or smartphone. Only a browser is enough to use these applications.
SaaS applications execute on the cloud servers. Our system only needs a good internet connection to use the application. Whenever we perform any action in the application, our system sends the request to the server. The server executes the request and sends a response to the application. Our system receives the response and displays it to us. All the computation and execution is done on the cloud server.

Benefits of using SaaS Apps
Access from anywhere: When you opt for a SaaS application, it becomes very easy to access it from any place or device connected to the internet. Most SaaS applications are now mobile-first, i.e., the preference is given to mobile application versions. The desktop and web-based versions are also available for most SaaS applications.
No app management: The end-user doesn’t have to manage the application. If any fault occurs, then the official team will be responsible for rectifying it. In the case of mobile and desktop applications, the user has to update the application regularly. But it is not a concern if you turn on automatic updates.
Easy to use– The SaaS application usage mostly depends on their User Interface. If the application is great but doesn’t have a good UI, the user won’t opt for it. So, primarily SaaS apps are very focused on user experience, making them easy to use.
Disadvantages of SaaS
Dependency on the Internet: The whole cloud computing experience depends on internet availability. If you don’t have internet access, then there is no way to access your applications.
Loss of control: As an end-user, we don’t have any control over the application. We can only use the features provided by the vendor and nothing more.
Data Security: When we register for any SaaS application, then it takes personal data from us. This data need to be in a secured database to avoid data leaks. There are instances in which companies sold their customer’s data. It possesses severe risks of privacy violations.
SaaS is the simplest cloud service model to use. No worries about servers or application management. Register yourself and start using the application. The web application versions help in low storage situations in your device, as you don’t want to install new applications.
