SaaS (Software as a Service)
Software as a Service (SaaS) Software as a service (SaaS) is a software distribution model in which a cloud provider hosts applications and makes them available to end users over the internet. In this model, an independent software vendor (ISV) may contract a third-party cloud provider to host the application.
Those who use SaaS, are able to access it through a web browser of their choice. On-premise implementation is not only different, but is a longer process. It features in-house installation – hosted and accessed on both company grounds and computers and cannot be accessed outside of company grounds.
