What's the difference between the Azure Event Grid and the Azure Service Bus Topics?

I've been trying to understand the difference between both services but i couldn't really find out. It looks to me they're both pub/sub services.

  1. The Azure Service Bus Topics is a loosely decoupled Pub/Sub PULL messaging model.

  2. The Azure Event Grid is a loosely decoupled Pub/Sub PUSH eventing model.


I do recommend to read the following document such as a foundation document for understanding Events, Data Points and Messages usage/concept, written by Clemens Vasters, Architect of the Azure Service Bus product:

https://azure.microsoft.com/en-us/blog/events-data-points-and-messages-choosing-the-right-azure-messaging-service-for-your-data/


also the other one, such as:

https://docs.microsoft.com/en-us/azure/event-grid/compare-messaging-services
