What is SaaS (Software as a Service)?

SaaS Definition

SaaS (Software as a Service) is a cloud-based software distribution model in which a service provider centrally hosts applications for customers and makes them available to customers via the Internet. Organizations typically pay for SaaS applications through a subscription fee on a monthly or annual basis. This contrasts with the traditional model of paying for software through a perpetual license, with upfront costs and optional ongoing support fees.
