The document discusses different cloud computing models including public, private and hybrid clouds. It explains that cloud computing refers to applications delivered as services over the internet, as well as the hardware and software that provides those services. Public clouds provide services to the general public in a pay-as-you-go manner, while private clouds are owned by a single organization. Hybrid clouds use a combination of private and public clouds. The document also discusses infrastructure as a service (IaaS), platform as a service (PaaS) and software as a service (SaaS) models and how they differ in terms of flexibility, abstraction and control.

- 26. What is The Cloud ? Slide 26… RossJimenez.com
- 27. The Cloud Defined Cloud Computing refers to both the applications delivered as services over the Internet and the hardware and systems software in the datacenters that provide those services. The services themselves have long been referred to as Software as a Service (SaaS). The datacenter hardware and software is what we will call a Cloud. When a Cloud is made available in a pay-as- you-go manner to the general public, we call it a Public Cloud. http://www.eecs.berkeley.edu/Pubs/TechRpts/2009/EECS-2009-28.pdf RossJimenez.com
