SaaS is a software distribution model in which a cloud provider hosts programs and makes them available to end customers via the internet.  In this case, an independent software seller could contract a third-party cloud provider to host the application. Alternatively, in the case of larger companies such as Microsoft, the cloud provider may also be the software provider.

Along with infrastructure as a service and platform as a service, SaaS is one of the three primary types of cloud computing. SaaS apps are used by a wide range of IT experts, commercial users, and consumer users. Personal entertainment, such as Netflix, to advanced IT tools, are all available. SaaS products, unlike IaaS and PaaS, are commonly offered to both B2B and B2C customers.

The cloud delivery model is used for SaaS. An ISV can hire a cloud provider to host the application and related data in the provider's data center or a software provider can use its own servers, databases, networking, and computing resources to host the program and related data. Any device with a network connection will be able to use the app. Web browsers are commonly used to access SaaS apps.
