By 2018, global data center traffic will reach 8.6 zettabytes per year with 76% of all data center traffic originating in the cloud, according to the newly published Cisco Global Cloud Index (GCI). Globally, cloud data center traffic will grow 3.9-fold by 2018, at a CAGR of 32% from 2013 to 2018.
The Cisco report assesses regional and country-level cloud-readiness by comparing average network speeds and latencies (fixed and mobile).
"When people discuss cloud, they often focus on public cloud services or public cloud storage services. However, a very significant majority of today's cloud workloads are actually processed in private cloud environments. Even with public cloud workloads having significant growth, by 2018, almost 70% of cloud workloads will still be private cloud-related, requiring the ability of workloads to bridge across a hybrid private/public cloud environment," said Kelly Ahuja, Cisco, Senior Vice President, Service Provider Business, Products, and Solutions.
Some highlights of the Cisco Global Cloud Index:
- By 2018, 53% of all residential Internet users globally will use personal cloud storage, and the average consumer cloud storage traffic per user will be 811 megabytes per month by 2018, compared to 186 megabytes per month in 2013.
- By 2018, 69% (113.5 million) of the cloud workloads will be in private cloud data centers, down from 78% (44.2 million) in 2013, and 31% (52 million) of the cloud workloads will be in public cloud data centers, up from 22% (12.7 million) in 2013.
- By 2018, traffic between data centers and end users will reach 1.5 ZB annually (17% of total data center tra ffic). 0.7 ZB (8%) will come from traffic between data centers, such as replication and interdatabase links. But the vast majority of data center traffic, 6.4 ZB (75%), will still be coming from within the data center, such as storage, production, development, and authentication traffic.
- The countries with the leading fixed network performance in 2014 are (in alphabetical order) Hong Kong, Japan, Korea, Luxembourg, the Netherlands, Romania, Singapore, Sweden, Switzerland and Taiwan.
- The countries with the leading mobile network performance in 2014 are (in alphabetical order) Australia, Belgium, China, Denmark, Korea, Luxembourg, New Zealand, Oman, Qatar and Uruguay.

- In October 2013, Cisco predicted global data center traffic will triple from 2.6 zettabytes in 2012 to 7.7 zettabytes annually in 2017, representing a 25 percent CAGR. The Cisco GCI forecast global data center traffic to grow threefold (a 25 percent CAGR) from 2012 to 2017, while global cloud traffic will grow 4.5-fold (a 35 percent CAGR) over the same period. Cisco estimated that cloud traffic globally will grow from grow from 46 percent of total data center traffic (98 exabytes per month or 1.2 zettabytes annually) of total data center traffic in 2012 to 69 percent of total data center traffic (443 exabytes per month or 5.3 zettabytes annually) of total data center traffic by 2017. http://www.convergedigest.com/2013/10/cisco-global-cloud-traffic-growing-at.html
