Monitorama PDX 2024 - Distributed Context Propagation: How you can use it to Improve Observability..

J. Kalyana Sundaram's session from Monitorama PDX 2024.
One of the main challenges in a complex distributed system is: How do we get all the participants on the same page about the “shared context” of a logical request? How do we do that in a vendor neutral and interoperable way? Say hello to distributed context propagation, also known as Baggage.
In this session, Kalyan will cover the "what", "why", and "how" of distributed context propagation. Baggage enables a variety of use cases in two categories: 1) improving the observability of a system and 2) enabling better control of a system. You will learn about use cases such as labelling synthetic traffic, chaos engineering, and attributing infrastructure spend. Kalyan represents the work done by the W3C Distributed Tracing Working Group that is driving the standardization of this mechanism (W3C Baggage). He will build together with you in a bottom-up manner the building blocks for solving this problem, and then extend that solution to be open and interoperable. You will also see a live demo of this built using the OpenTelemetry Baggage APIs.
