What does SaaS stand for?

Meaning and background of SaaS
Full formSoftware as a Service
CategoryTechnology & computing
TypeAbbreviation

The abbreviation SaaS stands for Software as a Service. It is a cloud service model in which customers use applications supplied by a provider rather than managing the underlying cloud infrastructure.

SaaS describes a delivery model, not a promise that software is free, secure for every purpose or available without configuration. Customers may control some application settings. The application and its account settings should be distinguished from the provider's underlying servers and operating systems.

Describe the application

Explain the job the application performs, not just its subscription label.

The SaaS application manages staff shift requests.

Clarify responsibility

Separate customer account configuration from the provider's infrastructure.

Compare service models

Ask what you are consuming: an application, a deployment platform or computing infrastructure.

Using the provider's hosted shift-planning application is different from renting a virtual server and installing our own application.
