Electrification was once called “the most important engineering achievement of the 20th century” by the National Academy of Engineering, and following a number of commercial uses all with different technologies and standards the technology converged and became commonplace in households (In large cities to begin with) during the 1920s.
In my view this evolution is not that dissimilar from the adoption of Cloud Services; before the inception of Broadband most institutions had little option but to build and run their own systems or get a partners to host. But post Broadband the ability to transmit data at fast speeds has seen the emergence of SAAS, PAAS, IAAS etc. which is evolving how enterprises procure technology and fix costs.
Even in the consumer space the use of the cloud is becoming more and more popular, especially if we think the new Apple operating system IOS5 includes iCloud and in the first 3 days of launching the Apple iPhone 4s 4million units were sold.
So if the enterprise and consumer are drifting into more and more cloud solutions could cloud Computing become a utility (Like Electricity) which we all subscribe to and get a monthly bill for usage??
