Cloud is the new paradigma for IT transformation. It makes possible to introduce a kind of revolution in your IT model. It helps you to make efficiency and improve company's income since Cloud shifts your IT expenditures from capex to opex. When you move into the Cloud you can think to evolve your business model in a way you never thought before since the Cloud makes you available all the resources you need with dynamic provisioning, great scalability, and paying for use.
Or perhaps do you think that Cloud is nothing new and it is just that a marketing guru changed the name to something that already existed since long ?
Every day I can talk with people thinking one way or the other.
Personally I'm convinced we're talking about something revolutionary since a company adopting Cloud services needs to RETHINK itsself in terms of business model, internal and external processes, competences, etc.
Of course if we just focus on the technological point of view, we can tell that what we actually call Cloud has some analogy with someother things in our past.
Here is an interesting infographic that illustrates these analogies from the past and the path towards the Cloud as is.
