In today’s digital world, Software-as-a-Service (SaaS) generally refers to a new and alternative way of accessing software, as opposed to more traditional methods of access.
Whereas in the past software would generally be purchased outright and loaded onto a device, SaaS normally refers to a subscription based model where the software is hosted in the cloud and accessed via the internet. There are a number of benefits of this to consumers, whether that is individuals using software for private purposes, or businesses.
There are many well-known examples of SaaS, including Office 365, Google Apps, Salesforce, Citrix GoToMeeting, Cisco WebEx and Netflix.
Examples of where SaaS can be used by enterprises:
- Accounting and invoicing
- Tracking sales
- Performance monitoring
- Communications (including webmail and messaging)
