How does Software As A Service or SaaS Work?

The emergence of SaaS is associated with cloud computing, it is regarded as one of the three categories of cloud-based computing. In past times, due to the need to constantly update computer softwares, early companies purchase compact disks containing updates before they are able to update software on their computers. But since SaaS came on board, updating softwares has been much easier for large companies. Once a copy of SaaS is installed on devices that need to access it, instead of purchasing compact disks, companies purchase software licenses which are available for downloads on the internet.
