Massive Surge in Cloud Datacenter Traffic Coming, Cisco Report Says


  1. According to the report’s authors, by 2021 hyperscale datacenters will support: 53 percent of all datacenter servers (27 percent in 2016) 69 percent of all datacenter processing power (41 percent in 2016) 65 percent of all data stored in datacenters (51 percent in 2016) 55 percent of all datacenter traffic (39 percent in 2016) The growth projected in the study is supported by a combination of security innovations and the benefits of virtualization and optimization, including scalability and economies of scale.
  2. Finally, applications will contribute significantly to the rise of global datacenter traffic, the report’s authors found, with the following results by 2021: Big Data will account for 20 percent of traffic within datacenters (2.5ZB annually, 209EB monthly), compared with 12 percent (593EB annually, 49EB monthly) in 2016.
  3. The company also expects cloud datacenter traffic to account for 95 percent of all datacenter traffic, globally, by 2021, compared with 88 percent in 2016.
  4. Global cloud datacenter traffic is likely to reach 20.6 zettabytes (ZB) per year by 2021, up from 6.0ZB per year in 2016, say the authors of a newly published report from networking giant Cisco.
