A Cisco forecast on cloud computing predicts cloud data center traffic around the world will increase 4.5-fold between 2012 and 2017, representing a 35 percent combined annual growth rate.
The third annual Global Cloud Index projects cloud traffic to grow from 1.2 zettabytes of annual traffic in 2012 to 5.3 zettabytes by 2017, Cisco said Tuesday.
One billion terabytes equals a zettabyte and Cisco also forecasts global data center traffic will grow threefold and reach 7.7 zettabytes per year by 2017.
By 2017, Cisco predicts 17 percent of data center traffic will be driven by end users accessing cloud environments to browse the Internet, stream video, collaborate and connect their devices.
“People all over the world continue to demand the ability to access personal, business and entertainment content anywhere on any device, and each transaction in a virtualized, cloud environment can cause cascading effects on the network,” said Doug Merritt, Cisco senior vice president of product and solutions marketing
“Because of this continuing trend, we are seeing huge increases in the amount of cloud traffic within, between and beyond data centers over the next four years.”
Africa and the Middle East are the regions Cisco believes will have the highest cloud traffic growth rate at 57 percent total, followed by the Asia-Pacific region at 43 percent and Central and Eastern Europe at 36 percent.
Cisco projects 7 percent of data center traffic to occur between data centers and mainly involve data replication and software or system updates.
Seventy-six percent of data center traffic is predicted to stay within the data center and mainly be generated by storage, production and development data in a virtualized environment, Cisco says.
