Cloud traffic to quadruple by 2019

Cloud traffic to quadruple by 2019 

This report projects a traffic jump from 2.1 zettabytes (ZB) to 8.6 zettabytes in worldwide cloud traffic. This is a gigantic increase that will outpace the growth of total global data center traffic, which is estimated to triple during the same period from 3.4 ZB to 10.4 ZB. 

FYI: a ZB is 2 to the 70th power bytes, or 1021 or 1 sextillion bytes and is equivalent to a thousand exabytes or a billion terabytes.

This projection is based on a number of factors that will help accelerate the growth of global cloud traffic, namely, the rapid growth public cloud services for business, personal cloud demands due to the increasing number of mobile devices, the increasing workloads for virtualization in private clouds and the growth of machine-to-machine connections. 

“The Global Cloud Index highlights the fact that cloud is moving well beyond a regional trend to becoming a mainstream solution globally, with cloud traffic expected to grow more than 30 per cent in every worldwide region over the next five years,” said Doug Webster, vice president of service provider marketing at Cisco. “Enterprise and government organizations are moving from test cloud environments to trusting clouds with their mission-critical workloads. At the same time, consumers continue to expect on-demand, anytime access to their content and services nearly everywhere. This creates a tremendous opportunity for cloud operators, which will play an increasingly relevant role in the communications industry ecosystem.”

This projected growth will create a remarkable opportunity for cloud operators, as currently 73 per cent of all data stored on devices are on PCs. Of this 51 per cent will migrate to non-PC devices by 2019; creating a greater demand for consumer cloud storage. 

The Cisco Global Cloud Index (2014-2019) was created to project global data center and cloud-based traffic growth and trends. It was generated by modeling and analysis of various sources and based on the examination of fixed and mobile network abilities of more than 150 countries worldwide.
