Fremont, CA: Edge-computing systems have few things in common: complex combinations of hardware, applications, infrastructure software, and networking, but that doesn’t mean they should have the same design. The server runs the analytics and the software-control systems to translate, for instance, large amounts of IoT data into actionable information. Open APIs are available on software and networking systems both to customize traffic flows. The network is formulated to deliver the latency and reliability required within the budget. Given the shifting that comes into play with each aspect of an edge system like devices, local network, gateway, and computing, it makes them all work to meet the required specifications and may need system-integration skills. Here is a brief look at these elements.

The range of devices that are collecting data at the edge of networks is rich. It includes sensors, medical devices, industrial machines, video cameras, actuators, asset monitors, RFID gear, self-order kiosks, tablets, PCs, phones, and a range of smart devices such as thermostats, refrigerators, and food preparation systems. The prime variables include the number and type of tools that are distant from the branch or campus network, the amount of data generated, battery life, and security requirements.
Gateway
Every gateway is an aggregation point for data generated by dispersed devices, but they might also filter, process, store, and apply security policies. Key variables are the type of device used, based on the needs of the system as a whole. The gateway can be anything from a server, a networking device to a specialized appliance.
Connectivity
With the number of devices comes a diversity of connectivity needs, from real-time high-bandwidth control of factory robots to moisture sensors in farm fields that has to upload small amounts of data at significant intervals. Enterprises have to decide the aptest links the kinds of edge devices they have deployed. The networking options include Wi-Fi, Bluetooth, Zigbee, private or public 4/5G, cellular data, and various kinds of wired connectivity, among others.
