The new Cisco Global Cloud Index forecasts that data centre traffic will grow four-fold by 2016, with global cloud traffic growing six-fold over the same period.
The second annual Global Cloud Index predicts that global data centre traffic will grow four-fold and reach a total of 6.6 zettabytes annually by 2016. At the same time global cloud traffic, the fastest-growing component of data centre traffic, will increase from 683 exabytes of annual traffic in 2011 to 4.3 zettabytes by?2016.
To put this into some sort of context, 6.6 zettabytes is equivalent to:
- 92 trillion hours of streaming music???equivalent to about 1.5?years of continuous music streaming for the world?s population in?2016.
- 16 trillion hours of business web conferencing???equivalent to about 12?hours of daily web conferencing for the world?s workforce in?2016.
- 7 trillion hours of online high-definition (HD) video streaming???equivalent to about 2.5?hours of daily streamed HD video for the world?s population in?2016.
For five years between 2011 and 2016, around 76% of data centre traffic will stay in the data centre and will be largely generated by storage, production and development data according to Cisco. Meanwhile another 17% of traffic will come from users accessing cloud-based applications for web surfing, emailing and video and audio streaming. The remaining 7% will be generated between data centres, driven by data replication and system upgrades.
Interestingly the Index also takes a look at ?cloud readiness?, 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. Some of the key factors to emerge from this analysis are:
- The average fixed broadband performance for Asia Pacific, Central and Eastern Europe, North America, and Western Europe can currently support advanced cloud-computing applications such as 3-D video streaming and high-end virtual office services.
- From a mobile network perspective, only the average network performance characteristics for Western Europe were sufficient to support intermediate cloud-computing applications today.
- The average mobile broadband performance for all other regions can support basic cloud-computing applications, such as web surfing and text communications (whilst it is worth noting that Hungary is the only country that can support advanced mobile cloud services today).
Commenting on the overall set of results Doug Merritt, senior vice president, Corporate Marketing, Cisco said ?This year?s forecast confirms that strong growth in data centre usage and cloud traffic are global trends, driven by our growing desire to access personal and business content anywhere, on any device. When you couple this growth with projected increases in connected devices and objects, the next-generation Internet will be an essential component to enabling much greater data centre virtualisation and a new world of interconnected clouds.?
