Cloud Traffic to Dominate Data Centers

The Cisco Global Cloud Index (GCI) report forecasts data center and cloud traffic as well as key trends for 2013-2018. Highlights include:

  • Global and regional data center and cloud traffic growth projections
  • Global and regional workload transitions (virtualization) from traditional IT to cloud solutions 

The GCI report assesses regional and country-level cloud-readiness* using broadband performance as a precursor for cloud service adoption by network consumers and business users.

* 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 November 2014, Cisco released its updated GCI report for 2013 – 2018. Highlights from the updated research include the following projections:

  • Global data center traffic will grow nearly three-fold 
  • By 2018, global data center traffic will reach 8.6 zettabytes per year
  • By 2018, 76 percent of all data center traffic will come from the cloud
  • By 2018, three out of four data center workloads will be processed in the cloud

From a regional perspective, the Cisco GCI predicts that through 2018, the Middle East and Africa region is expected to have the highest cloud traffic growth rate (54 percent compound annual growth rate [CAGR]); followed by Central and Eastern Europe (39 percent CAGR); and Asia Pacific (37 percent CAGR).
