Once upon a time, back when we all had mainframes and then servers in our offices, we had edge computing. Our compute power was literally down the hall. Then, along came the cloud, and all that changed. Computers were hundreds of miles but milliseconds away. Now, with the rise of IoT, 5G, and our never-satisfied need for speed, edge computing is coming back with a vengeance. Indeed, at his keynote at Open Networking Summit in Belgium, Arpit Joshipura, The Linux Foundation’s general manager of networking, said “edge computing will overtake cloud computing” by 2025.
When Joshipura is talking about edge computing, he means compute and storage resources that are five to 20 milliseconds away.
