Learn how Event Grid ensures message delivery.
- [Narrator] How good would an event delivery mechanism,…such as Event Grid be, if it missed the notifications…of the messages you're trying to send.…Well, there are a lot of facilities built…into the Event Grid that basically,…your messages don't go missing,…and that's on Delivery and Retry.…So the Tenets, that Event Grid takes…on is that each message is tried…at least once for each subscription.…
And that events are sent to the registered endpoint…of each subscription immediately.…So, it's almost near real-time.…If the endpoint doesn't acknowledge…the receipt of an event, Event Grid will automatically…retry the delivery of that message.…See why we're thinking,…"why don't I just do storage queues?"…Well, then you'd have to built…this retry logic yourself, right?…So it does simplify a lot of things.…So, Retry Schedule and Exponential Backoff…is based on this schedule.…
So, first it tries it in 10 seconds,…in the event of a failure, if that fails…then 30 seconds, then one minute…and this progressively increases to one hour.…

Azure Event Grid is a fully managed, intelligent event-routing service that allows for uniform and efficient event consumption using a publish-subscribe model. An alternative to expensive polling, Event Grid allows your services to talk to each other more efficiently and securely. This course demonstrates how to react to relevant events across Azure in near real-time fashion. Get an overview of Event Grid, and learn how it compares to other routing services: Service Bus, Event Hubs, and Queue Storage. Review the security features, and see how Event Grid handles message delivery when it doesn't get a response from an endpoint. Instructor Sahil Malik then demonstrates a practical use case for the technology, using Event Grid to react to Azure Blog Storage events.
