The document introduces cloud computing, defining it as an abstraction of the underlying internet infrastructure that allows users and applications to access scalable resources via the cloud without needing knowledge of the specific technology. Cloud computing abstracts the details of infrastructure from users, allowing applications hosted on the cloud to be dynamically scalable by using more resources when needed or releasing unused resources, saving companies from maintaining excess hardware.

1. CloudComputing.AtoZBible.com Introduction to Cloud Computing

2. Cloud = The term cloud is used as a metaphor for the internet

3. Internet = Internet is an abstraction of underlying infrastructure it conceals.

4. Cloud Computing =

5. Abstraction = The idea is to abstract the details from the users

6. Abstraction = Users no longer need knowledge of technology infrastructure in the cloud that supports them.

7. Applications Applications host on the cloud

8. Dynamically Scalable Applications host on the cloud are dynamically scalable.

9. Dynamically Scalable They can use more resouces if need be.

10. Dynamically Scalable They can release resource not needed at that time

11. Dynamically Scalable Companies dont have to worry about maintaining the extra hardware “just in case”.
