Slide 7 text

7 Remote Control of IoT Linux Devices | LinuxLab2018 - Firenze, IT CONTROL LINUX FROM THE WEB • Old problem, Old solutions • HTTPS is hard to achieve • Bi-directional communication • Work on most network topologies • Create a web server, contact it via http • Cannot have HTTPS unless domain name is registered and IP address is static/known • UDP port are often closed

9 Remote Control of IoT Linux Devices | LinuxLab2018 - Firenze, IT LANDSCAPE - DO NOT BE OVERKILL We do not want to store users’ data unless needed or with big advantages for both users and us. We do not want to deal with state synchronization. Scaling is really expensive!

15 Remote Control of IoT Linux Devices | LinuxLab 2018 - Firenze, IT ARDUINO CONNECTOR FEATURES One single binary ~20MB (no external deps) 01 Works on every Debian-like Linux distros 02 Works on slow connections 05 No need to know the IP in advance 06 Secure only connections 03 MQTT (Stable TCP socket with the remote server) 04

Slide 16

Slide 16 text

16 Remote Control of IoT Linux Devices | LinuxLab2018 - Firenze, IT MQTT is: • Well known • Widely used • Feature complete • Simple enough • Bi-directional I like AMQP more ;)

21 Remote Control of IoT Linux Devices | LinuxLab2018 - Firenze, IT APT integration is dummy, APT lib api are in C++ only and nearly impossible to integrate with Go, so we used the CLI as an API We released https://github.com/arduino/go-apt-client/ A combination of dpkg + apt commands wrapped in an API Supports managing repos APT INTEGRATION
