The rise of edge computing will come as no surprise to anyone following computing architectures during the past 40-plus years.
Although the topological concept of edge computing is decades old, it was only recently pushed into the limelight because of the limitations imposed by the centralized implementation of hyperscale cloud and the growing investment in the “internet of things.”
Edge computing places content, data and processing closer to the applications, things and users that consume and interact with them. It takes the traditional information technology workload quandary of “What goes where?” and encourages workload and capability placement that optimizes the balance of latency, bandwidth, autonomy and security across a continuum of options, from hyperscale cloud data centers to home thermostats.
As organizations strive to remain competitive in the digital business era, especially in a post-pandemic world, edge computing is a new enabler of customer insight and retention. Digital business relies on the convergence of the physical and the digital to create new business moments, and it benefits from and is enabled by edge. As one example, enterprises are using edge topological ideas to cut WAN costs dramatically, with one Gartner client cutting its WAN costs in half while improving resiliency and improving user experience.
