Cloud traffic to represent 95% of total data centre traffic by 2021: Cisco

Cloud data centre traffic is expected to represent 95 percent of total data centre traffic by 2021 compared to 88 percent in 2016, notes Cisco's Global Cloud Index for the period 2016 to 2021.

The domination of cloud-based data has been enabled by the meteoric growth of consumer and business applications such as streaming video, social networking, enterprise resource planning, analytics and digital enterprise applications.

Earlier today, Cisco released its Global Cloud Index for the period 2016 to 2021, estimating that global cloud data centre traffic will increase from a mere 6.0 zettabytes per year in 2016 to 19.5 zettabytes per year in 2021, thereby representing an annual growth rate of 27 percent. Thanks to such growth, global cloud data centre traffic will represent 95 percent of total data centre traffic by 2021.
