Thanks for the advice so far. I will propose a PoC along the following lines:
- Use gen_coap for the data plane.
- GenStage to do event processing.
- Store raw data an Azure Data Lake for Advanced Analytics. It is a strategy of the organisation to do all big data this way going forward. This is a ReST call to store information in the data lake.
- Simulate telemetry from 10,000 trucks/haulers/lorries that report GPS co-ordinates, speed, engine temperature, engine RPM, pneumatic system pressure and electrical system data at 1 second intervals — that is, we do 10,000 tps.
The primary goal is to use only technologies one gets with the standard install, and only packages from hex.pm. That is, I want to install stock Elixir and use only it and whatever I stick in my mix deps function to make it work, no need to install a database and a queuing system — unless it is absolutely necessary.
One question I have is which OS is better suited to the PoC? Linux or FreeBSD? I am an old Solaris kernel developer and are very familiar with Zones (Jails), DTrace and ZFS, but is that a good fit for “the masses”?
