Engineering organizations, which are moving to modern microservice architectures, realize that the majority of operational problems that arise when moving to a distributed architecture are in areas: networking and observability. As per-process logging and metric monitoring cannot reconstruct the elaborate journeys that transactions take as they propagate across a distributed system, there is a need to take a different approach. In this session, I will present OpenTracing, an open distributed tracing standard, and demonstrate how it helps Dev/DevOps engineers conducting service dependency analysis and investigating latency problems in microservice architectures.
