Connect to and consume Azure services and third-party services is a critical domain for Azure developers, encompassing approximately 15-20% of the AZ-204 exam. This area focuses on implementing secure and efficient communication between applications and various services.
API Management (APIM) serves as a gateway for managing APIs, providing features like rate limiting, authentication, caching, and transformation policies. Developers use APIM to create consistent API facades, protect backend services, and monitor API usage through analytics.
Event-based solutions involve Azure Event Grid and Event Hubs. Event Grid enables reactive programming with a publish-subscribe model, routing events from Azure services or custom sources to handlers. Event Hubs handles high-throughput data streaming, processing millions of events per second for telemetry and logging scenarios.
Message-based solutions utilize Azure Service Bus and Queue Storage. Service Bus provides enterprise messaging with features like topics, subscriptions, dead-lettering, and transactions. Queue Storage offers simple, cost-effective message queuing for decoupling application components.
Developers must understand when to choose each messaging pattern. Event Grid suits reactive, event-driven architectures. Event Hubs fits big data streaming scenarios. Service Bus handles complex enterprise workflows requiring guaranteed delivery and ordering. Queue Storage works well for basic asynchronous processing.
Authentication and authorization involve integrating Azure Active Directory, implementing OAuth 2.0 flows, managing service principals, and using managed identities to securely access resources. Developers configure connection strings, access keys, and shared access signatures appropriately.
Third-party service integration requires understanding REST API consumption, handling HTTP responses, implementing retry policies with exponential backoff, and managing circuit breaker patterns for resilience.
Key skills include configuring APIM policies in XML, implementing event handlers using Azure Functions, processing messages with SDKs, and troubleshooting connectivity issues. Developers should practice creating end-to-end solutions that combine multiple services while maintaining security, scalability, and reliability across distributed systems.Connect to and consume Azure services and third-party services is a critical domain for Azure developers, encompassing approximately 15-20% of the AZ-204 exam.
