Event Grid MQTT broker
An Event Grid MQTT broker is the MQTT publish-subscribe capability in Event Grid namespaces that authenticates clients, authorizes publish and subscribe requests, and routes MQTT messages between interested clients. Teams use it to connect MQTT clients, devices, and services through managed publish-subscribe messaging without running a separate broker platform. It is not a general Event Grid custom topic or an IoT Hub device registry replacement. In production, confirm the source, subscription, destination, filters, schema, identity, retry behavior, failure handling, monitoring, and owner before treating the route as safe.

Telemetry events
Telemetry events are breadcrumbs that say something meaningful happened in an application. They are different from raw logs because they usually have a clear event name and structured properties. A checkout completed, a document uploaded, a feature flag changed, or a device registered can all be telemetry events. In Azure Monitor Application Insights, these events help teams understand behavior, investigate incidents, and measure product outcomes.

Notification Hubs
Azure Notification Hubs is the Azure service teams use to send push notifications to mobile apps and connected devices. Instead of every backend talking separately to Apple, Google, or other platform notification systems, the app registers devices with a hub and the backend sends messages through that hub. It is useful for alerts, reminders, promotions, operational updates, and personalized messages. Notification Hubs does not replace the mobile app or messaging strategy; it provides the scalable push delivery layer behind them.

Cosmos DB spatial index
Cosmos DB spatial index is an indexing-policy entry that helps Cosmos DB for NoSQL query valid GeoJSON points, lines, polygons, and multipolygons efficiently. It makes location-aware queries practical without scanning every item in a container. You see it when applications store coordinates, service areas, delivery zones, device positions, or map features in JSON items. The production check is whether GeoJSON shape, indexed path, query function, and partition strategy all line up. Document the decision in code, templates, metrics, and runbooks.

Foreign key

Event Grid custom topic
Event Grid custom topic is a user-created Azure Event Grid topic that gives custom applications an endpoint for publishing business or application events. In Azure, it shows up when custom applications publish shipment, order, payment, device, or workflow events that subscribers need to process independently. Teams use it to review topic name, region, access keys or managed identity options, input schema, event subscriptions, filters, retry policy, dead-letter destination, and monitoring before changing production behavior. It is not an Azure system topic, Event Grid domain, Event Hub, or Service Bus topic.
