Cisco: Personal, Business Traffic Going to the Cloud
In its latest Global Cloud Index, the networking giant expects that worldwide cloud traffic will quadruple between 2014 and 2019.Global network traffic from data centers will triple between 2014 and 2019, and the cloud traffic that makes up an increasingly larger portion of that will continue to grow, quadrupling during the same time frame, according to Cisco Systems officials. In its fifth annual Global Cloud Index released this week, the networking giant said data center traffic worldwide will jump from 3.4 zettabytes last year to 10.4ZB in 2019 (a ZB is a 1 followed by 21 zeros). Global cloud traffic during that time will increase from 2.1ZB to 8.6ZB, driven in large part by the growing demand for personal clouds due to the increasing numbers of mobile devices, the rising use of public cloud services by businesses, and the growing use of virtualization in private clouds, which expands the density of the workloads. The report "highlights the fact that cloud is moving well beyond a regional trend to becoming a mainstream solution globally," Doug Webster, vice president of service provider marketing at 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." The Internet of things (IoT)—which Cisco officials call the Internet of everything (IoE)—and the growth in machine-to-machine (M2M) traffic also will contribute to the growth, according to the vendor. According to previously released numbers, Cisco officials are forecasting the number of connected devices and sensors that make up the IoT will jump from about 25 billion last year to more than 50 billion by 2020, and they will create massive amounts of data. They also expect the IoE will have a global financial impact on businesses of $19 trillion by 2020.
In the cloud index report, company officials said that, by 2019, the wide array of IoT applications will generate as much as 507.5ZB of data, or about 42.3ZB a month—49 times more than the projected data center traffic for that year.
