What is SaaS?

Software-as-a-Service (SaaS) is an evolution in the way enterprise applications are delivered to customers. Based around vendor hosting, the SaaS model evolved to negate many of the risks attached to traditional software solutions. By spreading the cost and removing the burden of operational management from the customer, the SaaS paradigm has simplified access to enterprise applications by abstracting all but the value-generating application functionality from the view of the customer. All software and hardware needs associated with the application are outsourced – no desktop installs, application servers or databases within the customer organization – and replaced by a 100% web front-end allowing access any time, anywhere.

The SaaS Architecture

SaaS is based on a multi-tenanted architecture. The vendor hosts a single instance of the application on a scalable "cloud" of hardware and provides access to multiple clients. The application logic, server storage and processing capacity is shared by all clients, with data securely separated using partitions.
