4. What’s in it?
   • Pay per event.
   • Sub-second end-to-end latency in the 99th percentile
   • 10.000.000 events per second per region
   • 24 hour retry with exponential back off

5. Concepts before we go deep.
   1. Events: what happened
   2. Event Publishers: where it took place
   3. Topics: where publishers send events
   4. Event Subscriptions: how you receive
   events
   5. Event Handlers: the app or service
   reacting to the event

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.
