5. SaaS: The Past, The Present, The future
Why SaaS
SaaS vs. Initial ASP
most initial ASP focused on managing and
hosting third-party independent software
vendors' software
SaaS vendors typically develop and manage
their own software
many initial ASP offered more traditional client-
server applications, which require installation of
software on users' personal computers
SaaS solutions are predominantly web-based
and only require an internet browser to use
The software architecture used by most initial
ASP mandated maintaining a separate
instance of the application for each business
SaaS solutions normally utilize a multi-
tenant architecture
