Azure Event Grid, Event Domains are in preview

Become your own event publisher with Event Domains, a feature that allows you to manage the outbound event flow of your application. Use the same tooling and architecture that Azure services (such as Azure Storage) use to publish their events. Event Domains handle the authorisation and authentication around subscribing to events within your Event Domain on a per-tenant basis and can manage massive numbers of parallel tenants while continuing to provide the reliable routing and delivery already available in Event Grid. This is a unique feature that none of our competitors have and it enables new scenarios for customers and partners who want to offer their own events for their end customers.
