Introduction to Cloud Computing
“There is no such thing as ‘the cloud,’ it’s just somebody else’s computer” – Did you ever hear that one?I have, and it’s what prompted me to create this course!
In this introduction to Cloud Computing, we answer the key question “What is the cloud?” With a solid, standards based approach and examples from the real word, we look at all the definitions that come together to mean cloud.
After this course you will have the foundation you need to launch into a career using cloud, to spearhead the cloud initiative within your organisation, or simply hold your own in that infuriating water cooler conversation with Simon the datacentre manager about how “there is no such things as ‘the cloud’”.
