capabilities, with the possible exception of limited user-
specific application configuration settings.

Cloud Platform as a Service (PaaS). The capability provided
to the consumer is to deploy onto the cloud infrastruc-
ture consumer-created 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 Infrastructure as a Service (IaaS). The capability pro-

vided 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 ap-
plications. The consumer does not manage or control the
underlying cloud infrastructure but has control over op-
erating systems, storage, deployed applications, and pos-
sibly limited control of select networking components
(e.g., host firewalls).

Deployment Models

Private cloud. The cloud infrastructure is operated solely
for an organization. It may be managed by the orga-
nization or a third party and may exist on premise or off
premise.
