Global cloud traffic is expected to quadruple by the end of 2019, from 2.1 to 8.6 zettabytes, according to the fifth annual Cisco Global Cloud Index released on Wednesday.
Despite fears that increased cloud adoption could do away with data centers, the two actually go hand-in-hand with cloud traffic to account for more than 83 percent of total data center traffic by 2019. Annual global data center IP traffic will reach 10.4 ZB by the end of 2019, up from 3.4 ZB per year in 2014. This is a good thing for Cisco, who currently has a majority hold of the cloud infrastructure equipment market, along with HP.
North America will have the highest cloud traffic volume (3.6 ZB) and data center traffic volume (4.5 ZB) by 2019, followed by Asia Pacific and Western Europe, respectively.
"The Global Cloud Index highlights the fact that cloud is moving well beyond a regional trend to becoming a mainstream solution globally, with cloud traffic expected to grow more than 30 percent in every worldwide region over the next five years," Doug Webster, vice president of service provider marketing, Cisco said in a statement. "Enterprise and government organizations are moving from test cloud environments to trusting clouds with their mission-critical workloads. At the same time, consumers continue to expect on-demand, anytime access to their content and services nearly everywhere. This creates a tremendous opportunity for cloud operators, which will play an increasingly relevant role in the communications industry ecosystem."
Personal cloud storage will drive some of this growth with 55 percent (more than 2 billion users) of the consumer Internet population will use personal cloud storage by 2019, up from 42 percent (1.1 billion users) in 2014.
Stored data moving from PCs to non-PC devices will contribute to this personal cloud growth. By 2017, global smartphone traffic will reach 201 exabytes (EB) per year will exceed the amount of data stored (179 EB per year), which Cisco says will necessitate the need for greater cloud storage capabilities.
Public cloud workloads are going to grow at a 44 percent CAGR from 2014 to 2019, with private cloud workloads growing at 16 percent CAGR from 2014 to 2019.
By 2019, 59 percent of the total cloud workloads will be SaaS workloads, up from 45 percent in 2014. Interestingly, IaaS workloads will decrease, with 30 percent of the total cloud workloads will be IaaS by 2019, down from 42 percent in 2014.
It’s impossible to talk about the future of cloud without addressing the Internet of Everything (IoE). Cisco expects data created by IoE connections to reach 507.5 zettabytes per year by 2019, up from 134.5 zettabytes per year in 2014.
