Cloud – from Conception to Completion
- 1. Cloud – from Conception to Completion Rob Gee Datacentre Architect
- 2. What is your perspective of Cloud Computing? “Once upon a time, there were six blind men. The blind men wished to know what an elephant looked like. The six blind men all perceived one aspect of the elephant and were each right in their own way, but none of them knew what the whole elephant really looked like.” Your definition of something may depend on your perspective… It’s like a rope! It’s like a wall! It’s like a fan! It’s like a snake! It’s like a spear! It’s virtualisation! It’s automation! It’s statelessness! It’s on-demand computing! Cloud Computing It’s a self-service portal! Its “Anything as a Service” (XaaS)! “Once upon a time, there were six IT people. The IT people wished to know what cloud computing looked like. The six IT people all perceived one aspect of the cloud and were each right in their own way, but none of them knew what the whole cloud really looked like.” Elephant It’s like tree!
