IaaS, PaaS, and SaaS may sometimes be referred to as cloud service offerings or cloud computing categories. But they all describe how you use the cloud in your company. Moreover, they define the level of service that you are in charge of in your cloud environments. "As a service" often implies that a third party offers the service model in the cloud. Platform as a Service (PaaS), Infrastructure as a Service (IaaS), and Software as a Service (SaaS) are the three main classes of cloud computing.

Moreover, organizations in the technology, financial services, entertainment, and utility sectors also influence the use of a SaaS platform. Additionally, users can also access the program online rather than installing it on their computers.

Before SaaS, businesses who wanted to update the software on their computers had to buy CDs holding the updates.
