*The Cisco Global Cloud Index (2013–2018) was developed to estimate global data centre and cloud-based traffic growth and trends. It is generated by modeling and analysis of various primary and secondary sources (complete methodology details are provided in the report).
Over the next five years, the study projects that data centre traffic will nearly triple, with cloud representing 76% of total data centre traffic. By 2018, half of the world's population** will have residential Internet access, and more than half of those users' (53%) content will be supported by personal cloud storage services.
Key Highlights include:
Global data centre traffic
The study predicts that global data centre traffic will nearly triple from 2013 to 2018 with a CAGR of 23%, growing from 3.1 zettabytes/year in 2013 to 8.6 zettabytes/year in 2018. A zettabyte is a trillion gigabytes.
The 8.6 zettabytes of data centre traffic predicted for 2018 is equivalent to streaming all of the movies (approximately 500,000) and television shows (3 million) ever made in ultra-high definition (UHD) 250,000 times.
Global cloud traffic is growing faster than the overall global data centre traffic. In 2013, cloud accounted for 54% of total data centre traffic, and, by 2018, cloud will account for 76% of total data centre traffic.
Data centre traffic includes data centre-to-user traffic along with data centre-to-data centre traffic, and traffic that remains within data centres.
Consumer cloud storage
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.
Cloud adoption and growth
"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.

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.
Cloud adoption and growth
"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.
By 2018, 69% (113.5 million) of the cloud workloads will be in private cloud data centres, down from 78% (44.2 million) in 2013, and 31% (52 million) of the cloud workloads will be in public cloud data centres, up from 22% (12.7 million) in 2013.
Global cloud readiness
The number of countries deemed "cloud ready" continues to grow. Last year (2013), 79 countries met the single advanced application criteria for fixed networks; this year (2014), that number grew to 109 countries. Last year (2013), 42 countries met the intermediate single application readiness criteria for mobile networks; this year (2014), that number grew to 52 countries.

The countries with the leading fixed network performance in Asia Pacific in 2014 are (in alphabetical order) Hong Kong, Japan, Korea, Singapore, and Taiwan. No Middle East countries were listed.
The countries in Asia Pacific and Middle East with the leading mobile network performance in 2014 are (in alphabetical order) Australia, China, Korea, New Zealand, Oman and Qatar.
To assess cloud readiness, average and median upload/download speeds and latencies were calculated based on global fixed and mobile network speed test analyses.

*The Cisco Global Cloud Index (2013–2018) was developed to estimate global data centre and cloud-based traffic growth and trends. It is generated by modeling and analysis of various primary and secondary sources (complete methodology details are provided in the report).
The Cisco Global Cloud Index serves as a complementary resource to existing Internet Protocol (IP) network traffic studies such as the Cisco Visual Networking Index, providing new insights and visibility into emerging trends affecting data centres and cloud architectures. The forecast becomes increasingly important as the network and data centre become more intrinsically linked in offering cloud services. The Cisco Global Cloud Index includes a "workload transition" forecast, which shows the workload shift from moving from traditional data centres to more virtualised cloud servers.
The forecast also includes a supplement on Cloud Readiness Regional Details, which examines the fixed and mobile network abilities of each global region (from nearly 150 countries) to support business and consumer cloud-computing applications and services.
**The world's projected population by 2018 will be 7.6 billion people according to the United Nations.
***Concurrent use of multiple applications requires even higher network performance capabilities than the requirements for individual application support shown above. Concurrent application requirements are covered in the Cisco Global Cloud Index Forecast and Methodology, 2013 – 2018.
