Week 11 centered on tracing, one of observability's three pillars, threading through the telemetry pipeline that standardizes it (ADOT) to the backends where data flows (OpenSearch·AMP·AMG). Today we reconstruct five days of concepts not as scattered facts but as one unified decision framework. The exam doesn't ask "what is X-Ray." It asks "why is the trace broken here," "what sampling configuration solves this cost problem," "what tool combo fits this multi-cloud requirement." Today's goal is practicing those judgments.
