If you have ever used tools like Google Docs, Zoom, or Dropbox, then you have already experienced SaaS in action. However, what exactly is SaaS, and why has it become the backbone of modern business technology?
In this guide, we will break down what SaaS is, how it works, what its benefits are, and why it is transforming the way individuals and businesses use Software.
What is SaaS?
SaaS stands for Software as a Service. It is a cloud-based method of delivering Software where users access applications over the internet, usually through a subscription model.
Instead of installing Software on individual computers or servers, SaaS applications run on remote servers, and users connect via web browsers or apps.
In simple terms:
SaaS = Software you use online without downloading or maintaining it yourself.
How Does SaaS Work?
SaaS operates through the cloud. The provider hosts the Software on their servers, maintains the infrastructure, handles updates, and ensures security.
All users need is:
- An internet connection
- A web browser or mobile app
- A subscription or log-in
The provider takes care of everything behind the scenes — hosting, maintenance, performance, and Scalability.
