This refers to moving or discarding an existing application and replacing it with commercial software delivered as a service, or SaaS. SaaS provides a complete software solution that you purchase on a pay-as-you-go basis from a cloud service provider.

When you choose this option, all underlying infrastructure, middleware, app software, and app data are managed by service providers and located in their datacenters. The service provider manages the hardware and software and, with the appropriate service agreement, will ensure the availability and security of the app—and your data as well. SaaS allows your organization to get quickly up and running with an app at minimal upfront cost. Typically, you migrate existing data to the SaaS environment. Application data import/export is achieved with an API or configuration/admin console.
