Show Notes

Detailed architecture comparison of Thanos (compactor, query, store) vs Cortex single-binary clustered architectures.

Key Takeaways

  • Thanos Query federates metrics from multiple Prometheus instances dynamically.
  • Object storage (S3/GCS) reduces monitoring compute costs by 90%.
  • Compactors aggregate metrics into downsampled blocks for fast queries.
