If there were any lingering doubts about the embrace of cloud computing across all industry sectors, the latest market analysis from Cisco ought to lay them to rest. Within the next three years, the study concludes, more than four-fifths of all data center traffic, 83 percent, will be based in the cloud. What’s more, most of this action will be going to public cloud services – there will be more workloads (56 percent) in the public cloud than in private clouds (44 percent). These are some of the many takeaways of Cisco’s survey of data center traffic, which estimates that more than 500 zettabytes (ZBs) of data will be generated by all people, machines, and things by 2019, almost five times the 135 ZBs generated in 2014. Roughly three to four zettabytes of it moves across data networks at this time, a number projected to grow to 10 ZBs within three years.
