In this AWS re:Invent 2023 session, Liz Fong-Jones, an AWS Community Hero and Field CTO at Honeycomb, discusses the importance of observability in production systems and how OpenTelemetry (OTel) simplifies the process. She explains how to implement OTel using AWS Distro for OpenTelemetry (ADOT), covering installation, data routing, and advanced techniques. The talk emphasizes the benefits of using OTel for generating telemetry data, including traces, metrics, and logs, and how it enables better understanding and debugging of complex distributed systems. Fong-Jones also highlights the flexibility of OTel in working with various backends and its potential to improve operational excellence and reliability.
