SAAS: THE PAYOFF
SaaS customers have no hardware or software to buy, install, maintain, or update. Access to applications is easy: You just need an Internet connection.
A multitenant architecture, in which all users and applications share a single, common infrastructure and code base that is centrally maintained, because SaaS vendor clients are all on the same infrastructure and code base, vendors can innovate more quickly and save the valuable development time previously spent on maintaining numerous versions of outdated code.
The ability for each user to easily customize applications to fit their business processes without affecting the common infrastructure, because of the way SaaS is architected, these customizations are unique to each company or user and are always preserved through upgrades that means SaaS providers can make upgrades more often, with less customer risk and much lower adoption cost.
Improved access to data from any networked device while making it easier to manage privileges, monitor data use, and ensure everyone sees the same information at the same time.
