http://www.awsguru.co.in - Cloud computing began as far back as the '60s. Some people trace it back to the ARPANET and CSNET, which were the predecessors of the internet, while others attribute it to various instances of mention over the years as computers and the internet grew. One of the earliest instances was in the '70s with the Remote Job Entry feature introduced for use by large companies such as IBM. However, the greatest acclaim to cloud computing can be given to Salesforce.com, who in the late '90s introduced what would be the pioneering beginning of modern cloud computing, with their delivery of applications over the internet to end users. The next critical mention was Amazon's web services in 2002, to provide a number of cloud services including storage and computation, among others through Amazon Mechanical Turk. From there cloud computing grew into what it is today, with more companies realizing the benefit and taking it up.
