Software as a service (SaaS) is a way of delivering applications over the Internet. Instead of installing and maintaining software, you simply access it via the Internet, freeing yourself from complex software and hardware management. SaaS provides IT with greater flexibility and a greater opportunity to deliver real business value to the organization through lower predictable costs.

SaaS removes the need for organizations to install and run their applications on their own computers with a third-party provider hosting the applications and making them available to customers over the Internet. This eliminates the costs associated with hardware acquisition, provisioning and maintenance, as well as software licensing, installation and support.
