What it actually costs to run this portfolio across AWS, Azure, GCP, and OCI simultaneously, with weighted DNS rotation between them. Numbers come from each provider's billing API, not marketing claims.
Live vs. estimated:
Cards tagged live pull from the cloud's billing API on a nightly cron.
Cards tagged est use a recent baseline value while the API integration is being wired up.
Why this exists: Most "multi-cloud portfolio" claims hand-wave the cost. Publishing the actual bill is a small act of FinOps practice and a forcing function to keep this thing under $5/mo. See architecture doc ↗
