Global Cloud Traffic to Increase 12-fold by 2015 Says Cisco

Through its inaugural Global Index of 2010 to 2015, Cisco, has estimated that traffic of global cloud computing will be growing 12 fold from the current 130 exabytes to a total of 1.6 zettabytes per year by the year 2015 which is a 66 percent compound growth rate per year.

In other words, 1.6 zettabytes is somewhat equivalent to 22 trillion hours of music streaming, 5 trillion hours of internet conferencing via webcam or simply 1.6 trillion hours of online HD video streaming.

Cloud happens to be, at present, the "fastest growing component of data centre traffic" that is predicted to grow by 4 fold at the rate of 33 percent CAGR to achieve 4.8 zettabytes per year by 2015, reported eWeek.

Thus, cloud is slowly turning into a very critical component for the future of Information Technology as well as delivery of content and also video.

Vice president of product and solutions marketing for Cisco, Suraj Shetty, said that, "Cloud and data centre traffic is exploding, driven by user demand to access volumes of content on the devices of their choice. The result: greater data centre virtualization and relevance of the network for cloud applications."
