On November 10th, we released the sixth annual Global Cloud Index Forecast, 2015 - 2020 (read media release). Global data center traffic is predicted to more than triple over the next five years. Cloud traffic will grow 3.7-fold and represent 92% of total data center traffic by 2020.

Here’s what you can learn from this year’s GCI update:

  • The number of global hyperscale data centers
  • The impact of SDN and NFV innovations on data center infrastructures
  • Global/regional workload transitions (virtualization) from traditional IT to cloud
  • Growth and workload density comparisons between public and private clouds
  • Growth and shifts in cloud service categories: IaaS, PaaS, and SaaS
  • Potential IoT impact on data centers as “Big Data” demands increase
  • The role security plays in protecting personal/business data and cloud transactions
