The document provides an overview of cloud computing including its essential characteristics, service models, and deployment models. It discusses the cloud computing model as composed of on-demand self-service, broad network access, resource pooling, rapid elasticity, and measured service. The service models are described as software as a service (SaaS), platform as a service (PaaS), and infrastructure as a service (IaaS). The deployment models covered are public, private, hybrid, and community clouds.

3. Cloud computing is a model for enabling
ubiquitous, convenient, on-demand network
access to a shared pool of configurable
computing resources (e.g., networks, servers,
storage, applications, and services) that
can be rapidly provisioned and released with
minimal management effort or service
provider interaction. This cloud model is
composed of five essential characteristics,
three service models, and four deployment
models.

24. Questions to Ask Yourself
How would we be harmed if
the asset became widely
public and widely distributed?

25. Questions to Ask Yourself
How would we be harmed if an
employee of our cloud provider
accessed the asset?

26. Questions to Ask Yourself
How would we be harmed if
the process or function were
manipulated by an outsider?

27. Questions to Ask Yourself
How would we be harmed if
the process or function failed
to provide expected results?

28. Questions to Ask Yourself
How would we be harmed if
the information/data were
unexpectedly changed?

29. Questions to Ask Yourself
How would we be harmed if
the asset were unavailable for
a period of time?
