-6. It is possible to run **multiple MQTT brokers** on the same device (see [6. MQTT brokers](#6-mqtt-broker)).
-7. A **USB memory stick** connected to the pi can be used for storing specific data (in this case it is the influxdb data) (see [section 7. USB memory stick](https://github.com/janvda/balena-edge-device-monitoring/blob/node-red/README.md#7-setup-of-the-usb-memory-stick)).

 ## 1. What
 The `node-red` branch of this github repository describes a composite docker application consisting of **"8"** containers that can be deployed through [BalenaCloud](https://www.balena.io/) on any arm device (e.g. a [Raspberry Pi 3 Model B+](https://www.raspberrypi.org/products/raspberry-pi-3-model-b-plus/)) running the [balena OS](https://www.balena.io/os/).
