Cloud Soon to Represent Three-Quarters Of Data Center Traffic, Cisco Predicts

Within the next four years, 76 percent of the traffic through the world’s data centers will be cloud-based traffic. Increasingly, this traffic will consist of public cloud services, as more enterprises become more comfortable with this model. Software as a Service will also dominate.
That’s the latest prediction from Cisco, which crunched the numbers in its latest Cisco Global Cloud Index (2013 – 2018). The Cisco report also forecasts that overall data center traffic will triple in volume, growing from 3.1 zettabytes a year in 2013 to 8.6 zettabytes in 2018. (A zettabyte is a trillion gigabytes.) The growth will be at least 23 percent annually…
Of course, global cloud traffic is growing faster than the overall global data center traffic. In 2013, cloud accounted for 54 percent of total data center traffic, and, by 2018, cloud will account for 76 percent of total data center traffic. Data center traffic includes data center-to-user traffic along with data center-to-data center traffic and traffic that remains within data centers. Already, the cloud data centers are generating a total of 2,277 exabytes of the total 3,829 exabytes being generated. By 2018, this proportion will be 6,496 exabytes of a total of 8,574 exabytes…
