What should I use to understand service dependencies

To understand service dependencies, the most useful thing is usually a service dependency map or dependency graph.
Depending on your environment, that can be built from:
- Service discovery / tracing tools
- e.g. OpenTelemetry, Jaeger, Zipkin
- Application dependency diagrams
- architecture docs or C4 model diagrams
- Cloud/platform observability tools
- e.g. AWS X-Ray, GCP Cloud Trace, Azure Application Insights
- System/service inventory tools
- CMDBs, service catalogs, or Kubernetes resource graphs
If you mean in practice, the best starting point is:
- Distributed tracing to see real runtime calls between services
- A dependency graph to visualize them
- Service ownership/catalog docs to explain why they depend on each other
If you want, I can also suggest the best tools specifically for:
- microservices
- Kubernetes
- AWS/Azure/GCP
- Python/Java/.NET systems
