Tie Cloud Costs to the Events That Caused Them

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.

This slows investigation and increases noise in monthly reporting.

Challenges

  • Cost data and events live in separate tools
  • RCA takes time and context is often lost
  • Knowledge doesn’t carry over across incidents
  • Engineers are stuck repeating investigations from scratch

How Costory Helps

Costory ingests technical and business events and aligns them with cost timelines.

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)

All events are timestamped and visualized alongside cost time series.

They also improve the accuracy of Digest summaries and ML-driven anomaly detection.

Benefits

  • Speeds up root cause analysis with event-aware timelines
  • Builds memory across engineering and finance
  • Improves accuracy of cost explanations and alerts
  • Increases confidence in cost anomaly RCA
