OpenTracing

In *OpenTracing: Practical Observability for Distributed Services*, readers will discover how distributed tracing has become a foundational practice for understanding, debugging, and operating modern microservices and cloud-native applications. As systems grow more fragmented across services, containers, and third-party dependencies, traditional monitoring alone is no longer enough to reveal where latency, errors, and hidden failures originate. This book explains how tracing exposes service interactions end to end, helping teams answer critical questions about request flow, dependency behavior, and system bottlenecks with clarity and precision.

The book provides a practical, accessible guide to OpenTracing fundamentals, including spans, traces, context propagation, and semantic conventions, while also covering both manual and automated instrumentation across popular languages and platforms. It walks readers through the full lifecycle of trace data-from collection and processing to storage, visualization, and real-time analysis-and shows how tracing integrates with orchestration platforms, service meshes, serverless environments, and incident response workflows. Along the way, it addresses key operational concerns such as performance overhead, scalability, privacy, compliance, and security, ensuring that observability remains both effective and responsible.

Through real-world examples and deployment lessons from large-scale and highly regulated environments, the book bridges theory and practice for engineers, architects, and technical leaders alike. It also looks ahead to the evolving observability landscape, including the transition to OpenTelemetry, the growth of open standards, and the emerging role of AI-assisted operations. With its focus on practical implementation and long-term value, *OpenTracing: Practical Observability for Distributed Services* is an essential resource for anyone building resilient, transparent, and future-ready distributed systems.
