Cloud-based applications — or software as a service — run on distant computers “in the cloud” that are owned and operated by others and that connect to users’ computers via the internet and (usually) a web browser.
Benefits of SaaS:
You can sign up and rapidly start using innovative business apps
Apps and data are accessible from any connected computer
No data is lost if your computer breaks, because the data is in the cloud
The service is able to dynamically scale to usage needs
