Register IoT Agent #22

Hi, I have a customer who'd like to make use of the FIWARE platform.

I personally come from a background of AWS and Azure and (perhaps wrongly) assumed an IoT Agent is equivalent of a "Thing" (AWS) or "Device"(Azure). In other words, this would represent the device connecting to the Context Broker.

-If this is the case, how do I provision new IoT Agents, accepting and providing keys and tokens for agents?

Let me read up a bit on AWS and Azure so we can define a common vocabulary of terms and I'll try to get back to you in a bit.

Meanwhile you could open a duplicate question on FIWARE Ask where there should be more community and eyeballs on the question.

Thank you for taking the time! To save you some time, here is a very high-level picture:

The image comes from MS but the structure is identical to AWS. My question relates to what in the picture refers to "IoT device library" or "IoT Edge". For the purpose of this discussion they are the same thing in that they are responsible for the connection to the IoT Hub.

The IoT hub has four main functions:

The device state, is one of the places where I'd expect the context broker to be superior. Device state is essentially just a json document shared between the IoT device and IoT Hub. It's powerful in that you can use it pretty much how ever you want such as for sensor- and meter configuration or firmware state etc. However there is no built-in modeling of entities such as with Context Broker.

Questions:

  1. Is it a fair statement to say that the Context Broker is the equivalent of the IoT Hub? if not, -what other parts would be involved on the cloud side of the solution?
  2. Where do I manage security such as tokens and certificates for things connected to the Brooker
  3. Is there a node js SDK I can use to connect to the Brooker (this one looks promissing ;))?

Again, thank you for sharing and I hope to return the favor ;) Mikael
