What is on-premises?
On-premises (on-prem) refers to software deployed within the organization's internal system along with the hardware and other infrastructure necessary for the software to function. Cloud-based software, such as software-as-a-service (SaaS) is usually delivered and experienced through the internet and it can be accessed by users online regardless of the time and their location.
Unlike on-premises software, SaaS services only need to install an application or a web browser in order to access it—regardless of whether the SaaS app is sanctioned by IT administrators or security.
