Running webservices on resource-limited embedded platforms
Thanks to IoT, the use of connected embedded platforms is exploding. How do you run webservices from slow CPU with few megs of RAM?
The Problem
Smart home, IoT, Arduino,... all these fancy buzzwords have one thing in common: low-cost hardware gets connected to the Internet. To integrate these connected devices with an existing system, some method of communication needs to be developed. Using HTTP REST API seems easiest and most straightforward way to do it. However, you cannot really run LAMP or node.js on a device with 120 MHz CPU and limited memory.
Experience from the Real World
The talk will cover struggles we had in Geolux when we first tried to run a simple webserver on an embedded platform used in our radar sensors. We will present the first framework we have selected, why it did not perform well, and how we managed to quickly switch frameworks/languages, while preserving most of the backend code.
Myth Busters!
We will try to debunk one commonly held myth related to programming languages and web development! Warning: heated discussion expected!
