Edge computing is becoming more and more popular, and Ubuntu maker Canonical innovates on the edge and IoT space with its popular Linux-based operating system, and now the London-based company aims to give developers new opportunities to innovate and hack on edge applications with the Raspberry Pi 4, Ubuntu Linux, and EdgeX Foundry as a snap. Turning a Raspberry Pi 4 computer into an Edge Gateway as an entry-level stack for IoT edge hacking, you will need, of course, the latest Raspberry Pi 4 Model B single-board computer (SBC) with the latest Ubuntu 19.10 (Eoan Ermine) operating system installed on it. The tutorial assumes you already have Ubuntu 19.10 installed on your Raspberry Pi 4 board.
