Cloud traffic to surge courtesy of IoT, says Cisco

Public cloud workloads will also post a 44 percent compound annual growth rate from 2014 to 2019 as private cloud grows at a 16 percent clip.

Global cloud traffic is expected to hit 8.6 zettabytes by the end of 2019, up from 2.1 ZB in 2014; data created by the Internet of things will hit 507.5 ZB by 2019; and public cloud workloads will grow at a 44 percent compound annual growth rate, according to Cisco's Cloud Index.

The Cloud Index is designed to be a planning document to study Internet Protocol network traffic. Cisco's Cloud Index complements its Visual Networking Index.

Based on Cisco's series of cloud stats, it's clear that traffic is about to surge to the point when we're commonly talking zettabytes. One zettabyte equals a billion terabytes. For instance, 8.6 ZB, or the cloud traffic in 2019, is equal to 5.7 trillion high-definition movies viewed online.

Among the key data points:

  • Annual global data center IP traffic will hit 10.4 ZB by the end of 2019, up from 3.4 ZB in 2014.
  • North America will have the most cloud traffic by 2019 with 3.6 ZB followed by Asia Pacific at 2.7 ZB and Western Europe at 1.8 ZB.
  • Fifty five percent of consumers will use personal cloud storage in 2019, up from 42 percent in 2014.
  • Consumer cloud storage traffic will be 1.6 GB per month, up from 992 MB per month in 2014. The bulk of stored data will move to non-PC devices.
  • Data created by IoT devices will hit 507.5 ZB per year by 2019, up from 134.5 ZB in 2014.
  • Public cloud workloads will have a compound annual growth rate of 44 percent from 2014 to 2019. Private cloud workloads will grow at a 16 percent clip. By workload, public clouds will have 56 percent of the workloads by 2019, up from 30 percent in 2014.
  • By 2019, 59 percent of total cloud workloads will be software as a service, up from 45 percent in 2014. Infrastructure as a service will be 30 percent of workloads by 2019, down 42 percent from 2014.
  • Eleven percent of cloud workloads will be platform as a service by 2019.
