Key points

• Event Grid matches discrete state-change events to subscriptions and attempts delivery to handlers.
• Filtering, delivery retry, endpoint health, and idempotent handling remain part of the event design.

Best-known use cases

• Notify several applications when a storage object is created, filtered by event attributes.

What candidates often confuse it with

• Event Grid routes discrete events; Event Hubs retains high-volume streams and Service Bus holds enterprise messages.

Key takeaway

Choose Event Grid when subscribers react to discrete resource or application events rather than consume a retained stream.
