Compared to desktop applications, web-based applications provide a whole range of business advantages. These applications can be accessed from any computer through the internet, instead of having to be individually installed on each computer that you wish to access it from. The use of web-based software is commonly called Software as a Service (SaaS), where apps run on a virtual, cloud-based environment; for example, the introduction of cloud-based email platforms has enabled users to access email on the go without installing a desktop email client. SaaS applications deliver tangible business benefits over on-premise software.
