Event Grid

Event Grid is Azure’s managed pub-sub system, handling event routing for applications and connecting directly with MQTT clients. It acts as a central hub for messaging, decoupling producers from consumers so services can react to state changes without direct integration. This setup simplifies building reactive architectures by managing the delivery and filtering of events automatically.

It suits teams already invested in the Azure ecosystem who need reliable, serverless event handling. The main friction point is the lack of a free tier; you pay strictly on a usage-based model from the start. This means even small prototypes or development environments incur costs, requiring careful budgeting if you’re testing event flows before committing to production scale.
