Microsoft Azure Architect Design (AZ-304) Practice Test

For a microservices architecture that supports automatic repairs and low-latency operations, what should be recommended?

1. Azure Kubernetes Service

2. Azure Container Service

3. Azure Service Fabric

4. Azure Virtual Machine Scale Set

The correct answer is: Azure Service Fabric

In the context of a microservices architecture that requires automatic repairs and low-latency operations, Azure Service Fabric stands out as the most fitting choice. This platform is specifically designed to support microservices applications by providing features such as lifecycle management, service discovery, and integrated health monitoring. Automatic repairs are integral to maintaining the availability and reliability of microservices. Azure Service Fabric has built-in support for self-healing capabilities; it can detect failures and automatically restart or shift services to other nodes within a cluster, ensuring minimal downtime. This capability is essential for modern applications that expect continuous availability and resilience. Furthermore, low-latency operations are critical in microservices environments where response time can significantly impact user experience. Service Fabric is engineered to facilitate high-performance communication between services, allowing for faster processing and interaction. Its support for both stateless and stateful services allows developers to optimize for performance and latency as needed. Other options, while useful in their own contexts, may not provide the same level of support for the unique requirements of microservices. For instance, Azure Kubernetes Service is primarily focused on container orchestration but may require additional setup for some of the advanced features that Service Fabric offers natively. Azure Container Service is a legacy product that has been superseded
