Internal Development of Jaeger at Uber

Uber engineers, led by Yuri Shkuro, commenced the development of an internal distributed tracing system, born out of the necessity to manage and debug their rapidly expanding microservices architecture. This period involved initial design, prototyping, and gradual rollout within Uber's massive infrastructure.
