What is Cloud Computing?

Last modified on May 26th, 2013 by Joe.

Some time back I created a presentation (ppt) for a session on introduction to cloud computing. The PPT slide used will help to understand “what is cloud computing?”. I thought of sharing the PPT with you. Download the presentation (PPT) on what is cloud computing.

Cloud Computing Origin

“Comes from the early days of the Internet where we drew the network as a cloud… we didn’t care where the messages went… the cloud hid it from us”
– Kevin Marks, Google

“The emerging cloud abstracts infrastructure complexities of servers, applications, data, and heterogeneous platforms”
– Jeff Bezos, CEO, Amazon.


What is Cloud Computing?

Cloud computing is a model for enabling 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 promotes availability and is composed of five essential characteristics, three service models, and four deployment models.
– National Institute of Standards and Technology (NIST) def–v15.
