Cloud Traffic To Rise To 14.1 ZB Per Year By 2020: Study
The 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, reveals the sixth Cisco Global Cloud Index. This rapid growth of cloud traffic is attributed to increased migration to cloud architectures due to 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 efficiency while flexibly delivering a growing variety of services to businesses and consumers with optimal performance. According to the report business workloads 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, the report said. The report further states that by 2020, database/analytics/Internet of Things (IoT) workloads will account for 22 percent of total business workloads, compared to 20 percent in 2015.
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.
“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,” said Doug Webster, Vice President of Service Provider Marketing, Cisco. “Powered by video, IoT, SDN/NFV and more, we forecast this significant cloud migration and the increased amount of network traffic generated as a result to continue at a rapid rate as operators streamline infrastructures to help them more profitably deliver IP-based services businesses and consumers alike”, he added.
