Service Models

Cloud Infrastructure as a Service (IaaS)
The capability provided to the consumer is to provision processing, storage, networks, and
other fundamental computing resources where the consumer is able to deploy and run
arbitrary software, which can include operating systems and applications. The consumer
does not manage or control the underlying cloud infrastructure but has control over
operating systems, storage, deployed applications, and possibly limited control of select
networking components (e.g., host firewalls).

Cloud Platform as a Service (PaaS)
The capability provided to the consumer is to deploy onto the cloud infrastructure consumercreated
or acquired applications created using programming languages and tools supported
by the provider. The consumer does not manage or control the underlying cloud
infrastructure including network, servers, operating systems, or storage, but has control over
the deployed applications and possibly application hosting environment configurations.

Cloud Software as a Service (SaaS)
The capability provided to the consumer is to use the provider’s applications running on a
cloud infrastructure. The applications are accessible from various client devices through a
thin client interface such as a web browser (e.g., web-based email). The consumer does not
manage or control the underlying cloud infrastructure including network, servers, operating
systems, storage, or even individual application capabilities, with the possible exception of
limited user-specific application configuration settings.
