The document discusses cloud security and the risks associated with cloud adoption. It begins with an introduction to cloud computing models including infrastructure as a service (IaaS), platform as a service (PaaS), and software as a service (SaaS). The document then outlines public, private, community, and hybrid cloud deployment models and trends in cloud adoption for 2017. It identifies policy/organization, technical, legal, and generic risks of cloud computing and concludes with recommendations around effective onboarding, vendor analysis, risk management and contract management when adopting cloud services.

4. CloudEcosystem
Cloud computing is the delivery of computing services—servers, storage,
databases, networking, software, analytics and more—over the Internet (“the
cloud”).

Cloud Service Models
Infrastructure as a Service
Platform as a Service
Software as a Service
Application platform or
middleware as a service on
which developers can build and
deploy custom applications
Compute, storage, IT infra as
a service, rather than as
dedicated capability
End-user applications
delivered as a service rather
than on-premises software
SaaS
(consume)
PaaS
(build)
IaaS
(host)
