  11. What about Event Hubs?
    • Event Hub is an “event ingestor” that accepts and stores event
    data, Azure Event Grid is the distribution fabric for discrete
    “business logic activity” events.
    • Fast and highly parallelized processing of the individual
    streams instead of a filtered subscriber model.
