What You'll Learn​

  • Centralized logging patterns: Regional aggregation first, then central, vs direct-to-central trade-offs
  • Data transfer cost mitigation: Sampling strategies, compression, local-first analysis
  • Distributed tracing architecture: Correlation IDs, trace context propagation, cross-region visualization
  • Metrics aggregation: Regional Prometheus, central Thanos/Cortex, cross-region query federation
  • Real-world costs: Observability can be 10-15% of infrastructure spend if not designed carefully
