What is the difference between IaaS, SaaS and PaaS?

Cloud computing has become the lifeline of all kinds of organizational set-ups- whether big or small. Through cloud computing, organizations can share unlimited virtual resources present in the cloud.


Cloud technology services are of three types:


  • IaaS (Infrastructure as a Service)
  • SaaS (Software as a Service)
  • PaaS (Platform as a Service)


What is SaaS:

SaaS or Software as a Service, as the name suggests, is a cloud technology service, where the SaaS provider hosts various applications on the cloud and makes them available to customers over the internet. SaaS is also known as cloud application services and is one of the most commonly used cloud services.

The SaaS provider, apart from making the application available to the end-users, will also be responsible for providing services such as managing the client’s data, storage, and managing the application’s updates. Most of the SaaS applications will run on the web browsers directly. This means that the end-users will just need a computer with an internet connection and a browser to access the applications.
