Cisco reveals that Global Cloud traffic will outpace growth of global data center traffic

Cisco Systems which designs and manufactures networking equipment predicts that cloud computing traffic will quadruple by the end of 2019 and will outpace the growth of global data center traffic.

Cisco in its fifth annual Global Cloud Index report predicted that Global cloud traffic is expected to grow from 2.1 to 8.6 zeta bytes in comparison to the total global data center traffic that is expected to triple during the same time frame from 3.4 to 10.4 zeta bytes.

Increase in mobile devices like smart phones that are calling for increased need of cloud storage will be contributing on a major note for the huge surge in cloud traffic. Further, the rapid growth in cloud traffic has also been attributed to increased adoption of cloud services by business as well as an increased degree of virtualization in private clouds.

Cisco believes that increase in machine-to-machine (M2M) connections or Internet of Things (IoT) also has the potential to drive more cloud traffic in the future. It further clarified that the increase in Internet of Everything (IOE) i.e. connecting everything like people, processes, data and things, to internet will also play a major role in increase in cloud data as well as data center traffic.

Cisco says that IoE applications have the potential of generating large volumes of data that could reach 507.5 ZB per year (42.3 ZB per month) by 2019. That’s 49 times greater than the projected data center traffic for 2019 (10.4 ZB).

Cisco says that as of today, 73 per cent of data stored on client devices resides on PCs, but over the course of next four years, the majority of stored data (51 per cent) will move to non-PC based devices like smart phones, tablets, M2M modules and such.

This transition will lead to increase in the usage of consumer cloud storage and it is estimated that by 2019, over 55% of the residential internet population will use personal IP Storage– up from 42% in 2014.

Cisco’s fifth annual Global Cloud Index report terms cloud traffic as a subset of data center traffic, which is generated by cloud services accessible through the internet from scalable, virtualized cloud data centers, whereas total data center traffic is comprised of all traffic traversing within and between data centers as well as to end users.

So, Cisco predicts annual global data center IP traffic to reach 10.4 Zeta bytes by the end of 2019, up from 3.4 Zeta bytes per year in 2014.
