Applications in the cloud (Software as a Service - SaaS).
This layer provides capability for consumers to use the
provider's applications running on a cloud infrastructure. For
instance, the applications are accessible from various client
devices through a thin client interface such as Web browser.
The consumer does not manage or control the underlying cloud
infrastructure including network, servers, operating systems,
storage, or even individual application capabilities. In this type
of cloud service model, the security and privacy protection is
provided as an integral part of the SaaS to the healthcare
consumers.
