What is SaaS: SAP Software-as-a-Service

SaaS stands for software-as-a-service. It is a way of delivering applications/apps over the web/internet. Customers can access SaaS apps right from any web browser via any of their devices (mobile, PC, tablet), which means there is no requirement to buy, install, maintain, or update any hardware or software. The SaaS provider (here it is SAP) will take care of every next required operation– and the customer will always have the latest version of the application.
Following are the major SaaS products:

•  SAP SuccessFactors HR Solutions
•  SAP Hybris Cloud for Customer
•  Ariba Network: Sourcing, Procurement, & Finance
•  Concur: Travel & Expense Management
