It is expected that cloud traffic will increase up to up to four times over the next four years. This means that the amount of cloud traffic will go up from 3.9 zettabytes (ZB) per year as measured in 2015 to 14.1 ZB by 2020. This is according to a study released recently by Cisco.
To give some perspective on this figure: According to Wikipedia, In 2013, one expert estimated that the amount of data generated worldwide would reach 4 zettabytes by the end of that year.
There are several factors influencing the growth including business workloads dominating data centre applications, meanwhile for consumers the growth of social media and video is predicted to increase in popularity further. By 2020 it is predicted that even internet of things will hold a 22 percent share on data loads.
Cisco has commented, “In the six years of this study, cloud computing has advanced from an emerging technology to an essential scalable and flexible part of architecture for service providers of all types around the globe,”
With the growth of social media, internet of things (IoT) & video and further emerging technologies, Cisco predicts the amount of traffic to continue to grow at a rapid rate advanced by operators who streamline their IP-based services aimed at businesses and consumers.
