Data center traffic will nearly triple, with cloud representing 76 percent of total data center traffic, said Cisco Global Cloud Index (2013 – 2018) issued today.
By 2018, half of the world’s 7.6 billion people (projected) will have residential Internet access, and 53 percent of those users’ content will be supported by personal cloud storage services.
Global data center traffic will nearly triple to to 8.6 zettabytes/year in 2018 from 3.1 zettabytes/year in 2013 with a combined annual growth rate (CAGR) of 23 percent.
Cloud traffic is growing faster than the overall global data center traffic. By 2018, cloud will account for 76 percent of total data center traffic against 54 percent in 2013.
Data center traffic includes data center-to-user traffic along with data center-to-data center traffic and traffic that remains within data centers.
53 percent of all residential Internet users will use personal cloud storage, and the average consumer cloud storage traffic per user will be 811 megabytes per month by 2018 against 186 megabytes per month in 2013.
69 percent (113.5 million) of the cloud workloads will be in private cloud data centers by 2018, down from 78 percent (44.2 million) in 2013, and 31 percent (52 million) of the cloud workloads will be in public cloud data centers, up from 22 percent (12.7 million) in 2013, said Cisco.
The number of countries deemed cloud ready continues to grow. The number of countries that met the single advanced application criteria for fixed network grew to 109 in 2014 from 79 in 2013.
The number of countries that met the intermediate single application readiness criteria for mobile networks increased to 52 in 2014 against 42 in 2013, said Cisco.
