A zettabyte is one billion terabytes. For context, 7.7 zettabytes is equivalent to:
•107 trillion hours of streaming music - about 1.5 years of continuous music streaming for the world's population in 2017. •19 trillion hours of business web conferencing - about 14 hours of daily web conferencing for the world's workforce in 2017. •8 trillion hours of online high-definition (HD) video streaming - about 2.5 hours of daily streamed HD video for the world's population in 2017.
Approximately 17 percent of data center traffic will be fueled by end users accessing clouds for web surfing, video streaming, collaboration and connected devices, all of which contribute to the Internet of Everything, which is the networked connection of people, data, process and things.
Other data center traffic is not caused directly by end users, but by data centers and cloud-computing workloads used in activities that are virtually invisible to individuals. For the period 2012-2017,
"People all over the world continue to demand the ability to access personal, business and entertainment content anywhere on any device, and each transaction in a virtualized, cloud environment can cause cascading effects on the network," said
From a regional perspective, the Cisco Global Cloud Index predicts that through 2017, the
•The Cisco Global Cloud Index (2012-2017) was developed to estimate global for data center and cloud-based Internet Protocol (IP) traffic growth and trends. The Cisco Global Cloud Index serves as a complementary resource to existing network traffic studies, providing new insights and visibility into emerging trends affecting data centers and cloud architectures. The forecast becomes increasingly important as the network and data center become more intrinsically linked in offering cloud services. •The Cisco Global Cloud Index includes a "workload transition" forecast, which shows the workload shift from moving from traditional data centers to more virtualized cloud servers. •The forecast also includes a supplement on Cloud Readiness Regional Details, which examines the fixed and mobile network abilities of each global region (from nearly 150 countries) to support business and consumer cloud-computing applications and services. •The Cisco Global Cloud Index is generated by modeling and analysis of various primary and secondary sources, including 40 terabytes of monthly traffic sampled from a variety of global data centers over the past year, results from more than 90 million network tests, and third-party market research reports.
