Azure Event Grid
Azure Event Grid is a fully managed event routing service in Microsoft Azure that enables event-driven, reactive programming by connecting event sources (like Azure services, custom applications, or third-party services) to event handlers (like Azure Functions, Logic Apps, or webhooks). It uses a publish-subscribe model to deliver events reliably and at scale, supporting filtering and routing based on event types or content. This service simplifies building decoupled, serverless applications by handling event distribution without requiring infrastructure management.
Developers should use Azure Event Grid when building event-driven architectures in Azure, such as for real-time notifications, automation workflows, or integrating disparate services without tight coupling. It is ideal for scenarios like processing IoT telemetry, reacting to changes in Azure resources (e.g., blob storage updates), or orchestrating microservices, as it reduces complexity by offloading event routing and ensures low-latency delivery with built-in retry mechanisms. Learning it is valuable for cloud-native development, especially in Azure ecosystems where event-based patterns are common.
