Cisco Shares GCI Forecast Results

Global cloud traffic will more than quadruple from 2012 to 2017. (13:40 min)

The Cisco Global Cloud Index (GCI) forecasts data center and cloud traffic and related trends:

  • Data center and cloud traffic forecast offers projections from 2012-2017 on global data center and cloud traffic rates.
  • Workload transition provides 2012-2017 projections for workloads* moving from traditional IT to cloud solutions.
  • Cloud readiness** provides regional and country-level data on broadband performance as a precursor for cloud service adoption by network consumers and business users.

* A workload is defined as an independent service or collection of code that can be executed.

** Cloud readiness compares average global network speeds and latencies (fixed and mobile) to assess each region's (or country's) ability to support a sample set of cloud services.


In October 2013, Cisco released the Cisco Global Cloud Index Forecast, 2012 - 2017. Highlights from the updated research include the following projections:

  • Global data center traffic will grow three-fold from 2012 to 2017.
  • By 2017, global data center traffic will reach 7.7 zetabytes per year.
  • By 2017, over two-thirds of all data center traffic will come from the cloud.
  • By 2017, nearly two out of three data center workloads will be processed in the cloud.
