1Cisco Forecasts Traffic in the Cloud Will Only Get Busier
2Traffic is Going One Way–Up
According to Cisco’s numbers, global data center traffic will grow from 3.4 zettabytes last year to 10.4ZB by 2019. During that same time, worldwide cloud traffic will quadruple, from 2.1ZB to 8.6ZB, due in large part to growing demand for personal clouds as the number of mobile devices increases, growing public cloud services for business and the rise of virtualization in private clouds.
3What Does 10.4ZB Look Like?
It’s equal to 144 trillion hours of streaming music (26 months of continuous music streaming for the world’s population in 2019), 26 trillion hours of business Web conferencing with a webcam (21 hours of daily Web conferencing for the global workforce in 2019), or 6.8 trillion HD movies viewed online (2.4 hours of daily streamed HD moves for the world’s population n 2019).

8Virtualizing Everything and Using the Cloud
Overall data center workloads will more than double from 2014 to 2019, while cloud workloads will more than triple. In addition, workload density—workloads per physical server—in traditional data centers will increase from 2 in 2014 to 3.2 in 2019, while in cloud data centers, it will jump from 5.1 last year to 8.4 by 2019.
9Public and Private Clouds
Public cloud use is growing faster than private cloud use. Public cloud workloads will grow 44 percent a year from 2014 to 2019, while private cloud workloads will increase at 16 percent. The percentage of cloud workloads in public cloud data centers will jump from 30 percent last year to 56 percent in 2019, while the percentage in private clouds will drop from 70 to 44 percent.

11Getting Ready for the Cloud
Cisco looks at the average and median upload/download speeds and latencies of fixed and mobile networks of more than 150 countries to gauge cloud readiness. The company found that in 2015, 81 countries met the single advanced application readiness criteria for mobile networks, up from 21 countries last year. In 2015, 119 countries met the criteria for fixed networks, an increase from 109 in 2014.
