This document provides an overview and introduction to cloud computing concepts. It discusses the myths and facts about clouds, advantages like economies of scale, and definitions including the notion that clouds provide abstraction of hardware and software infrastructure. It also covers different cloud types (private, public, SaaS, PaaS, IaaS), open source cloud platforms, cloud utilities, major cloud users, cloud standards, and the Amazon EC2 and EBS cloud services.

4. Cloud Talk
The Myths
(The Big Switch “Nick Carr” Syndrome)
Cloud computing will eliminate the need for IT
personnel.
There will only be one super computer in the future.
Cloud Hype
Everything is a cloud.

5. Cloud Talk
The Facts
Cloud technology is real
This technology should not be ignored
This presentation will try to separate the hype

6. Cloud Talk
The Advantages
Economies of scale 10’s->100’s->1000’s
Common cloneable infrastructures
Elastic and Autonomic
The possibly of green computing

7. Cloud Talk
What is the Basis of a Cloud
Abstraction of the hardware infrastructure from the
service.
Some say it must have an API.

8. Cloud Talk
What is my definition of a
“Holy-Grail” Cloud
Abstraction of the hardware infrastructure from the
service.
