Cloud traffic will represent over two-thirds of global data center traffic by 2017 and will grow more than fourfold from 2012 to 2017, according to a newly released CiscoGlobal Cloud Index. The report forecasts that global cloud traffic, the fastest growing component of data center traffic, is expected to grow 4.5 times at 35% CAGR from 1.2 zettabytes of annual traffic in 2012 to 5.3 zettabytes by 2017.

The study further reveals that overall global data center traffic will grow three-fold and reach a total of 7.7 zettabytes annually by 2017. Approximately 17% of data center traffic will be fueled by companies accessing clouds for web surfing, video streaming, collaboration and connected devices, all of which contribute to the Internet of Everything, which is the networked connection of people, data, process and things.

Other data center traffic is not caused directly by users, but by data centers and cloud-computing workloads used in activities that are virtually invisible to individuals. Till 2017, Cisco forecasts that 7% of data center traffic will be generated between data centers, primarily driven by data replication and software or system updates. An additional 76 % of data center traffic will stay within the data center and will be largely generated by storage, production and development data in a virtualized environment.

“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, Senior Vice President, Product and Solutions Marketing, Cisco. “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.”

From a regional perspective, the Cisco Global Cloud Index predicts that through 2017, the Middle East and Africa will have the highest cloud traffic growth rate (57% CAGR), followed by Asia Pacific (43 % CAGR) and Central and Eastern Europe (36% CAGR).

Asia Pacific data center traffic will grow 3.6-fold by 2017, at a CAGR of 29% from 2012 to 2017 and cloud data center traffic will represent 68% of total data center traffic by 2017, compared to 41% in 2012. Consumer will represent 79% of cloud data center traffic by 2017, compared to 74% in 2012. The study also predicts that Asia Pacific leads in the number of subscribers throughout the forecast period due to the region’s large population.
