Computing Evolution
Now40’s 70’s 80’s
•Mobility explosion
•Collaboration
•High level of interconexion between users
•Web platform growing
•Pressure over companies data centre.

Why
Contrary to last “big innovations”, cloud computing didn’t sprout from a young genius from Silicon valley. “is the logical result from the last 30 years in computation. In certain way, is a return to past, time sharing taken to the maximum”.
•Just 6% of currently installed servers capacity is used•30% aren’t used but weren’t unplugged from the network.
Definition It combines a lot of concepts from latter years in computing: a huge number of multicore PCs and servers (both physical or virtual) running together trough broadband networks..
Why Amazon was pioneer: they have a critical mass in Christmas, but during the rest of the year, they have the infrastructure available and developed a lot of technology so support their business.

How we see it
The subject is still blur, and opinion of experts and executives from customers and suppliers are diverse:
▲Definitive
▲Will kill another ways of computing
▲Will be the computing itself
▼Another fade
►Just a name for “Network virtualization”
