Microsoft Certified: Azure Developer Associate (AZ-204)Connect to and consume Azure services and third-party servicesEasy
A company is developing a new microservices application. They need to implement a solution that allows different microservices to react to events occurring within other services, such as a new user registration or an order status update. The solution must be highly decoupled, serverless, and support a wide variety of event sources and handlers. Which Azure service is best suited for this event-driven architecture?
- AAzure Logic Apps
- BAzure Event Grid
- CAzure Event Hubs
- DAzure Service Bus Queues
Show answer & explanationAnswer & explanation
Correct answer: B. Azure Event Grid
Azure Event Grid is a serverless event routing service that enables developers to easily build event-driven architectures. It supports events from various Azure services and custom sources, delivering them to multiple handlers, making it ideal for decoupling microservices and reacting to state changes.
Why the other options are wrong
- A. Azure Logic Apps are for workflow automation and integration, and while they can consume events, they are not the core event routing backbone itself.
- C. Azure Event Hubs is designed for high-throughput data streaming and ingestion, not for general-purpose event routing in a reactive microservices architecture.
- D. Azure Service Bus Queues are for reliable message queuing between applications, not primarily for event routing to multiple subscribers from diverse sources.
Azure Event Grid
A serverless event routing service that helps you build event-driven architectures.
- Enables reactive programming across Azure services.
- Supports custom topics for application-specific events.
- Delivers events to multiple handlers with flexible filtering.
Memory trick: Event Grid is the super dispatcher for all your Azure events.
