WAN Costs Might be a Bigger Edge Computing Driver than Latency

By 2025, perhaps 75 percent of enterprise data will be generated outside enterprise data centers or cloud data centers, according to Cisco. 

While today only 10 percent of all data is handled at the edge, analysts expect in three years between 50 percent and 75 percent of all data to be produced and processed at the edge,” said Paul Morgan, Global Sales for Manufacturing, Automotive & IoT, at HP Enterprise (HPE).  “Gartner puts the figure at 75 percent.”

And even if latency is an issue for some edge applications, conrtainment of bandwidth costs also matters. If much of that data can be processed locally, wide area network bandwidth costs are lower.
