Kubernetes and Cloud Native Associate (KCNA)Cloud Native ArchitectureMedium
A team is developing a new cloud-native application using microservices. They want to implement a robust monitoring solution that provides deep insights into the behavior of individual requests as they traverse multiple services. This includes tracking latency, errors, and the path a request takes through the system. Which observability technique is best suited for this requirement?
- AHealth Checks
- BMetrics Collection
- CLog Aggregation
- DDistributed Tracing
Show answer & explanationAnswer & explanation
Correct answer: D. Distributed Tracing
Distributed tracing is designed to track requests as they flow through multiple services in a microservices architecture, providing a holistic view of the request path, latency, and any errors encountered across services.
Why the other options are wrong
- A. Health Checks verify the availability and responsiveness of individual services, not the flow of a request through the entire system.
- B. Metrics Collection gathers numerical data about system performance (e.g., CPU usage, request count), providing aggregates but not per-request insights across services.
- C. Log Aggregation collects and centralizes logs from various services, useful for debugging but not for tracking a single request's journey.
Distributed Tracing
An observability technique used in microservices architectures to track a single request as it propagates through multiple services, providing a detailed view of the request's journey, latency, and any errors.
- Tracks individual requests across services.
- Provides end-to-end visibility.
- Helps identify performance bottlenecks and errors.
- Complements logs and metrics.
Memory trick: Observe with Logs, Metrics, and Traces.
