Study Notes
Azure Messaging Services
Azure Service Bus
- A fully managed enterprise service bus that enables communication between applications and services
- Supports multiple communication protocols, including AMQP, HTTP, and REST
- Features:
- Queues: temporary storage for messages
- Topics: publish-subscribe model for messages
- Relays: enables bi-directional communication between applications
Azure Queue Storage
- A messaging service for decoupling applications and services
- Enables asynchronous communication between components
- Features:
- Queues: stores messages for processing
- Messages: can be up to 64KB in size
- Visibility timeout: allows for retries in case of failures
Azure Event Grid
- An event-driven service that enables event-based communication between applications and services
- Features:
- Event subscribers: can be Azure Functions, Logic Apps, or webhooks
- Event handlers: can be Azure Functions, Logic Apps, or webhooks
- Event sources: can be Azure services, custom applications, or third-party services
Azure Event Hubs
- A fully managed, real-time event ingestion service
- Enables event-driven architectures and stream processing
- Features:
- Event hubs: partitioned, log-structured repositories for events
- Event producers: can be Azure services, custom applications, or third-party services
- Event consumers: can be Azure Functions, Logic Apps, or custom applications
Key Concepts
Messaging Patterns
- Request-response: synchronous communication between applications
- One-way: asynchronous communication between applications
- Publish-subscribe: event-driven communication between applications
Event-Driven Architecture
- Enables loose coupling between applications and services
- Enables scalability, flexibility, and fault tolerance
- Enables real-time processing and analytics
Use Cases
- Microservices communication: enables decoupling and asynchronous communication between microservices
- IoT and telemetry: enables real-time event processing and analytics
- Serverless architectures: enables event-driven communication between serverless functions
