About 40 percent of enterprise information technology executives believe their firms will deploy edge computing solutions within 12 months, a survey of about 800 organizations by IDC suggests. And though justifications of edge computing value tend to center on ultra-low latency computing response, the top value was viewed by enterprise IT executives as “bandwidth cost savings,” reported by nearly 30 percent of respondents.
Security was the number-two value, cited by 27 percent of respondents. Deterministic latency was cited as a primary motivation for edge computing by just 19 percent of respondents. The point is that the value touted by suppliers is not necessarily the value as seen by buyers.
On the other hand, the near-term value--and the justifications for spending money--are different. Some 39 percent of respondents say security is the immediate driver of benefit. That tends to be true of the other near-term benefits as well. The immediate benefits are operational, not yet strategic.
About 39 percent of respondents say operating efficiency is an immediate driver of edge computing spending. Another 35 percent say improving customer experience is the immediate benefit.
Still, latency performance is recognized as an edge computing value proposition. That likely accounts for the large percentage of respondents who believe internet of things applications, process automation and operational awareness are prime beneficiaries of edge computing.
Perhaps significantly, an overwhelming percentage of respondents reported that their edge deployments were needed to reduce latency to less than five milliseconds.
