Cloud traffic to more than quadruple in 2019: Cisco

Cloud traffic will more than quadruple
Global cloud traffic will more than quadruple in 2019 from 2.1 to 8.6 zettabytes (ZB), according to the fifth annual Cisco Global Cloud Index (2014-2019).

During this period, global data center traffic will triple from 3.4 to 10.4 ZB.

The personal cloud demands of mobile devices; the growth in popularity of public cloud services for business, and the virtualization in private clouds and machine-to-machine (M2M) connections will drive more cloud traffic in the future.

Cloud traffic is expected to grow more than 30 percent in every worldwide region over the next five years.

“Enterprise and government organizations are moving from test cloud environments to trusting clouds with their mission-critical workloads,” said Doug Webster, vice president of service provider marketing, Cisco.

Internet of Everything (IoE) could have a significant impact on data center and cloud traffic growth. A range of IoE applications are generating volumes of data that could reach 507.5 ZB per year (42.3 ZB per month) by 2019. That’s 49 times greater than the projected data center traffic for 2019 (10.4 ZB).

73 percent of data stored on client devices resides on PCs. By 2019, 51 percent of stored data will move to non-PC devices such as smartphones, tablets, M2M modules, etc.

By 2019, 55 percent of the residential Internet population will use personal cloud storage against 42 percent in 2014.
Annual global data center IP traffic is projected to reach 10.4 ZB by the end of 2019, up from 3.4 ZB per year in 2014.

Annual global cloud traffic is projected to quadruple, reaching 8.6 ZB (719 EB per month) in 2019 from 2.1 ZB per year (176 EB per month) in 2014, and is expected to account for more than four-fifths (83 percent) of total data center traffic by 2019.

New technologies such as SDN and NFV are 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.

North America will have the highest cloud traffic volume (3.6 ZB) by 2019; followed by Asia Pacific (2.3 ZB) and Western Europe (1.5 ZB).

North America will also have the highest data center traffic volume (4.5 ZB) by 2019; followed by Asia Pacific (2.7 ZB) and Western Europe (1.8 ZB).

Overall data center workloads will more than double from 2014 to 2019; however, cloud workloads will more than triple over the same period.

The workload density for cloud data centers was 5.1 in 2014 and will grow to 8.4 by 2019. For traditional data centers, workload density was 2.0 in 2014 and will grow to 3.2 by 2019.

The data created by IoE connections will reach 507.5 zettabytes per year (42.3 zettabytes per month) by 2019, up from 134.5 zettabytes per year (11.2 ZB per month) in 2014.

A smart city of 1 million will generate 180 million gigabytes of data per day by 2019.

The Cisco Cloud Index projects that public cloud workloads are going to grow at 44 percent CAGR from 2014 to 2019 and private cloud workloads will grow at 16 percent CAGR from 2014 to 2019.

56 percent of the cloud workloads will be in public cloud data centers by 2019 against 30 percent in 2014.

44 percent of the cloud workloads will be in private cloud data centers by 2019 against 70 percent in 2014.

SaaS will be the most popular and adopted service model for public and private cloud workloads, respectively, by 2019.

59 percent of the total cloud workloads will be Software-as-a-Service (SaaS) workloads by 2019 against 45 percent in 2014.

30 percent of the total cloud workloads will be Infrastructure-as-a-Service (IaaS) workloads by 2019 from 42 percent in 2014.

11 percent of the total cloud workloads will be Platform-as-a-Service (PaaS) workloads by 2019 from 13 percent in 2014, said Cisco.
