New figures released by Cisco have shown that 34% of total data centre traffic will be accounted for by global cloud computing traffic by 2015, up from 11% in 2010.
In the latest Global Cloud Index (2010-2015) report published by Cisco, the networking infrastructure giant estimates a 12-fold increase in global cloud computing traffic from 130 exabytes in 2010 to 1.6 zettabytes a year by 2015.
In 2015, monthly global cloud-based data exchanges will reach 137 exabytes, up from 11 exabytes last year.
Overall, global cloud computing traffic will increase at a compound annual growth rate (CAGR) of 66% from 2010 to 2015.
The report also said that more than half of workloads will be processed in cloud data centres by 2014.
As part of the Cisco Global Cloud Index report, "more than 30 terabytes of data generated each month over the past year from a variety of data centres around the globe" were analysed, together with "more than 45 million broadband-speed tests, and third-party market forecasts".
