1Cloud to Be Dominant Form of Data Center Traffic by 2021, Cisco Reports
The cloud, which already has had a dramatic impact on data traffic, will account for 95 percent of all data center traffic by 2021, according to a new report from Cisco. The Cisco Global Cloud Index (2016-2021) was released on Feb. 5, providing insight into cloud trends and data patterns. Cisco forecasts that global cloud data center traffic will grow from 6.0 zettabytes in 2016 to 18.9ZB per year by 2021. Cisco is also projecting that software-as-a-service (SaaS) will be the leading cloud service model through 2021, accounting for 75 percent of cloud workloads. In this slide show, eWEEK looks at some of the highlights from the Cisco Global Cloud Index (2016-2021) report.
2Cloud Dominates Data Center Traffic
3Traditional Data Center Traffic Still Growing
4Most Data Center Traffic Stays Inside Data Centers
5Public Cloud Usage Outpaces Private Cloud
6Workload and Compute Density Grows in the Cloud
Among the reasons why cloud data centers are growing are the increased efficiency and density of workloads. Cisco has a metric for workload and compute instance density that measures the average number of workloads and compute instances per physical server. Looking at cloud servers, the workload and compute instance density is set to grow from 8.8 in 2016 to 13.2 by 2021.
7Majority of Cloud Workloads Are SaaS
8Software-Defined Networking Use Growing
One of the key trends identified by Cisco is that software-defined networking (SDN) adoption will grow in data centers from 16 percent in 2016 to 67 percent in 2021.
