This document discusses cloud computing and different types of cloud models. It defines cloud computing as internet-based computing where shared resources, software, and information are provided on-demand over the internet. The document outlines characteristics of cloud computing like elasticity and pay-per-use. It distinguishes between public clouds, which are off-site resources provided by third parties, and private clouds, which emulate public clouds on private networks but require more management. Examples of public and private cloud providers are also given. The presenter's contact information is provided at the end.

3. What is Cloud ComputingCloud computing is Internet-based computing, whereby shared resources, software and information are provided to computers and other devices on-demand, like electricity.It is a paradigm shift following the mainframe and client-server shifts that preceded it. Details are abstracted from the users who no longer have need of, expertise in, or control over the technology infrastructure "in the cloud" that supports them. Cloud computing describes a new supplement, consumption and delivery model for IT services based on the Internet, and it typically involves the provision of dynamically scalable and often virtualized resources as a service over the Internet. It is a byproduct and consequence of the ease-of-access to remote computing sites provided by the Internet.

6. Public CloudPublic cloud or external cloud describes cloud computing in the traditional mainstream sense, whereby resources are dynamically provisioned on a fine-grained, self-service basis over the Internet, via web applications/web services, from an off-site third-party provider who shares resources and bills on a fine-grained utility computing basis

7. Private CloudPrivate cloud and internal cloud are buzzwords that some vendors have recently used to describe offerings that emulate cloud computing on private networks. These (typically virtualization automation) products claim to "deliver some benefits of cloud computing without the pitfalls", capitalizing on data security, corporate governance, and reliability concerns. They have been criticized on the basis that users "still have to buy, build, and manage them" and as such do not benefit from lower up-front capital costs and less hands-on management, essentially "[lacking] the economic model that makes cloud computing such an intriguing concept"
