Cloud Traffic to Dominate Data Centers

The Global Cloud Index report forecasts data center and cloud growth with related trends for 2014 – 2019. Highlights include:

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

Our report assesses cloud-readiness* regional and country-level traffic data on 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 October 2015, Cisco released its updated GCI report for 2014 – 2019. Highlights from the updated research include the following projections:

  • Global data center traffic will grow nearly 3-fold 
  • By 2019, global data center traffic will reach 10.4 zettabytes per year
  • By 2019, 83 percent of all data center traffic will come from the cloud
  • By 2019, 4 out of 5 data center workloads will be processed in the cloud

From a regional perspective, the Global Cloud Index predicts that through 2019, the Middle East and Africa region is expected to have the highest cloud traffic growth rate (41 percent CAGR); followed by Central and Eastern Europe (38 percent CAGR); and North America (33 percent CAGR).
