When cloud costs spike, teams scramble to answer: “What changed?” Often the root cause is known — a deployment, new region, or event like Black Friday — but there’s no structured correlation between these events and the cost data.

​
How Costory Helps

Costory ingests technical and business events and aligns them with cost timelines. Event Correlation Supported inputs include:
  • AWS commercial events (SPs, RIs, EDP renewals)
  • GitHub metadata (PRs, deploys, labels)
  • CI/CD pipelines (custom events via API)
  • Manually created events (e.g., traffic spikes, client onboarding)
Event Correlation All events are timestamped and visualized alongside cost time series. They also improve the accuracy of Digest summaries and ML-driven anomaly detection. Event Correlation
