In the fourth annual Cisco Global Cloud Index (2013 – 2018) issued today, Cisco Systems Inc.  forecasts continued strong growth of cloud traffic, cloud workloads and cloud storage with private cloud significantly larger than public cloud. Over the next five years, the study projects data centre traffic to nearly triple, with cloud representing 76% of that traffic.

It will have a combined annual growth rate (CAGR) of 23%, growing from 3.1 zettabytes/year in 2013 to 8.6 zettabytes/year in 2018. A zettabyte is trillion gigabytes.

The 8.6 zettabytes of data centre traffic predicted for 2018 is equivalent to streaming all of the movies (approximately 500,000) and television shows (3 million) ever made in ultra-high definition (UHD) 250,000 times.

On the consumer front, 53% of all residential Internet users globally will use personal cloud storage, and the average consumer cloud storage traffic per user will be 811 MB per month by 2018, compared to 186 MB per month in 2013.

The United Nations has projected that the world’s population by 2018 will be 7.6 billion people.
