The fifth annual Cisco Global Cloud Index (2014-2019) forecasts that Middle East and Africa (including South Africa) cloud traffic will more than quadruple by the end of 2019. Additionally, by 2019, 83 percent of all MEA data center traffic will come from the cloud.
From a regional perspective, the report found that MEA is expected to have the highest cloud traffic growth rate at 41 percent by 2019. Several factors are driving cloud traffic’s accelerating growth and the transition to cloud services, including the personal cloud demands of an increasing number of mobile devices; the rapid growth in popularity of public cloud services for business, and the increased degree of virtualisation in private clouds which is increasing the density of those workloads. The growth of machine-to-machine (M2M) connections also has the potential to drive more cloud traffic in the future.
“The Cisco Cloud Index highlights the fact that cloud is moving well beyond a regional trend to becoming a mainstream solution, with cloud traffic expected to grow more than 30 percent in every worldwide region over the next five years,” reveals Vernon Thaver, CTO of Cisco South Africa. “South African enterprise and government organisations are moving from test cloud environments to trusting clouds with their mission-critical workloads. At the same time, consumers continue to expect on-demand, anytime access to their content and services nearly everywhere. This creates a tremendous opportunity for cloud operators, which will play an increasingly relevant role in the communications industry ecosystem.”
In addition to the rapid growth of cloud traffic, Cisco predicts that the Internet of Everything (IoE)—the connection of people, processes, data and things—will have a significant impact on data center and cloud traffic growth. Today, only a small portion of this content is stored in data centers, but that could change as the application demand and uses of big data analytics evolves (i.e. analysing collected data to make tactical and strategic decisions).
New technologies such as SDN and NFV are also expected to streamline data center traffic flows, such that the traffic volumes reaching the highest tier (core) of the data center may fall below 10.4 ZB per year and lower data center tiers could carry over 40 ZB of traffic per year. To help put things in perspective, 10.4 ZB is equivalent to:
– 144 trillion hours of streaming music: Equivalent to about 26 months of continuous music streaming for the world’s population* in 2019
– 26 trillion hours of business web conferencing with a webcam:Equivalent to about 21 hours of daily web conferencing for the world’s workforce in 2019
– 8 trillion of high-definition (HD) movies viewed online: Equivalent to about 2.4 hours of daily streamed HD movies for the world’s population in 2019
– 2 trillion hours of ultra-high definition (UHD) video streaming: Equivalent to about 25 minutes of daily streamed UHD video for the world’s population in 2019
Here are some of the MEA (including SA) key highlights from the Cisco Cloud Index:
– Data center traffic will grow 4.0-fold, up by 32% from 2014 to 2019
– Cloud data center traffic will represent 86% of total data center traffic by 2019, compared to 61% in 2014
– Consumer will represent 61% of cloud data center traffic by 2019, compared to 30% in 2014
– 1% of data center traffic will travel between data centers by 2019, compared to 7.1% in 2014.
