What is Spring Cloud Sleuth used for in microservices?
A) Distributed tracing of requests across services
B) Load balancing of microservices
C) Managing security policies
D) Centralized logging
Answer:
A) Distributed tracing of requests across services
Explanation:
Spring Cloud Sleuth is used for distributed tracing in microservices architectures. It adds trace and span IDs to requests as they move through various microservices, enabling developers to track the entire lifecycle of a request from start to finish.
This tracing capability is critical for monitoring and debugging microservices, especially when trying to identify bottlenecks or failures in complex, distributed systems. Sleuth integrates with tools like Zipkin or Jaeger to provide a comprehensive view of how requests are processed across the system.
