•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”
