Global cloud traffic is expected to rise 3.7-fold, up from 3.9 zettabytes (ZB) per year in 2015 to 14.1 ZB per year by 2020. The recently released sixth annual Cisco Global Cloud Index (2015-2020) reveals that in Middle East and Africa (MEA), data center traffic will reach 451 exabytes per year by 2020, up from 105 exabytes per year in 2015. This rapid growth of cloud traffic is attributed to increased migration to cloud architectures and their ability to scale quickly and efficiently support more workloads than traditional data centers.
With greater data center virtualization, cloud operators are also able to achieve greater operational efficiencies while flexibly delivering a growing variety of services to businesses and consumers with optimal performance. To better understand data center growth, new analysis on application workloads was developed for this year’s report.
The following business and consumer projections were highlighted:
· Business workloads dominate data center applications and are growing. Business workloads will grow by 2.4 fold from 2015 to 2020 but their overall share of data center workloads will decrease from 79 to 72 percent.
· Consumer workloads, while smaller in number, are growing faster. During the same time, consumer workloads will grow faster by 3.5 fold.
By 2020, consumer workloads will account for 28 percent (134.3 million) of total data center workloads, compared to 21 percent (38.6 million) in 2015.
By 2020, video streaming workloads will account for 34 percent of total consumer workloads, compared to 29 percent in 2015.
By 2020, social networking workloads will account for 24 percent of total consumer workloads, compared to 20 percent in 2015.
· IoT/analytics/database workloads are growing the most in terms of share of business workloads with collaboration and compute workloads largely maintaining their share.
· Video and social networking will lead the increase in consumer workloads, each respectively grows their percentage significantly.
By 2020: video streaming workloads will account for 34 percent of total consumer workloads, compared to 29 percent in 2015; social networking workloads will account for 24 percent of total consumer workloads, compared to 20 percent in 2015; search workloads will account for 15 percent of total consumer workloads, compared to 17 percent in 2015.
“Over the past year, we’ve seen a variety of businesses and organizations develop plans for cloud migration or adoption. The move to the cloud is imminent as cloud computing has advanced from an emerging technology to an essential scalable and flexible networking solution. With multiple trends influencing the growth of data center and cloud computing such as increasing digitization, the widespread adoption of multiple devices and connections and the growth of mobility, the importance of cloud readiness cannot be overemphasized,” said Mike Weston, Vice President, Middle East, Cisco.
“Although our region has made significant strides to reach a capable level of supporting basic and intermediate cloud services, the focus now turns to continuing to improve network capabilities to support the advanced cloud applications that organizations and end users expect and rely upon,” added Mr Weston.
For the first time, Cisco also quantified and analyzed the impact of hyperscale data centers. These data centers are expected to grow from 259 in 2015 to 485 by 2020. Hyperscale data center traffic is projected to quintuple over the next five years. These infrastructures will account for 47 percent of total data center installed servers and support 53 percent of all data center traffic by 2020.
A key infrastructure trend is transforming hyperscale (and other) data centers. Software-defined networking (SDN) and network functions virtualization (NFV) are helping to flatten data center architectures and streamline traffic flows. Over the next five years, nearly 60 percent of global hyperscale data centers are expected to deploy SDN/NFV solutions. By 2020, 44 percent of traffic within data centers will be supported by SDN/NFV platforms (up from 23 percent in 2015) as operators strive for greater efficiencies.
