Event Hub
What is it
https://azure.microsoft.com/en-us/services/event-hubs/
Fully Managed Service (PaaS) for ingesting events/messages at a massive scale (think telemetry processing from websites, IoT etc).
What does it do in our wind farm
Provides a “front door” to our wind farm application to accept all of the streaming telemetry being generated from the turbines. Event Hubs wont process any of this data per se – its just ensuring that its being accepted and queued (short term) while other components cane come in to consume it.
Before you dig deeply into particular services, it’s nice to see how they fit together at a higher level.
