Go (Golang) for IoT Backends

Go was built at Google for fast, reliable networked services — a good match for the servers and gateways that IoT fleets depend on.

Go compiles to a single, fast native binary and has built-in support for handling many things at once, which suits the backend side of IoT: a server juggling connections from thousands of devices, forwarding their data, and responding to commands, all without the heavier setup that some older languages need for that kind of concurrency.

Go isn't generally used to program the microcontroller inside a sensor itself; instead, it tends to appear one layer up, in gateways, cloud services, and command-line tools that manage fleets of devices, largely because of its combination of speed, simple deployment, and a standard library well-suited to networking.

Its straightforward syntax and fast compile times have also made it popular for internal tooling — the scripts and services engineering teams write to flash devices, collect logs, or monitor a fleet of deployed hardware.
