Studies examining the impact of cloud computing on both current and future business trends are numerous and they quite regularly produce some similar forecasts. Most frequently, cloud computing is found to be a technological buzzword of the decade with a very bright future.
More recently, Cisco’s Global Cloud Index report confirmed the predicted growth of cloud computing systems. Considering the rate at which the cloud grows in popularity the number may not be that surprising after all – the annual global cloud traffic will increase from 683 exabytes in 2011 up to 4.3 zettabytes in 2016.
Cloud traffic is the fastest-growing component of global data center traffic and Cisco predicts that it will constitute two thirds of it by 2016. At the moment, many companies already apply cloud computing technologies in some way especially in the US. The data from 2011 point out that North America is the leader in the amount of generated cloud traffic – 261 exabytes. The transition from traditional cloud servers is expected to grow particularly in the regions of Middle East and Africa which are predicted to have the highest rate of cloud traffic growth.
This traffic is primarily related to the data center workflow and only a part of it comes from individual users. Even though the Internet is a household item nowadays, the individual users do not generate much traffic and Cisco predicts that in the next several years the situation will remain more or less the same. Only 17% of cloud traffic will actually be generated by end users to access online services, while the rest will predominantly be related to data centers and will be invisible to end users.
In addition, the study examined mobile broadband performance across different regions. The data from the study point to further development of mobile broadband considering the increased use of mobile devices. Europe is currently very weak in terms of mobile broadband, so it is expected that it will have the highest growth rate.
The necessities for mobile solutions and connected workflow are getting more important and it is obvious that this trend is very likely to continue in future as well. The usage of cloud computing systems already represents a must in business world and considering the expected growth of data stored and transferred online, the cloud technologies are expected to be significantly improved.
Doug Merritt, senior vice president in Cisco Corporate Marketing summarizes the findings of their report:
This year’s forecast confirms that strong growth in data center 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 center virtualization and a new world of interconnected clouds.”
