    Provider Coverage

    Every service, instance family, and pricing model the simulator models for each cloud provider. Counts and base rates are derived from the canonical pricing constants — the same numbers used by the simulation engine.

    Accuracy label guide
    Measured
    Validated against real provider benchmarks — latency, cost, and CPU metrics are fit to reference data from the provider's own documentation and publicly available performance studies.
    Extrapolated
    Derived from the simulation model — behavior is modeled from first principles or scaled from adjacent measured services, without a direct benchmark validation pass. Suitable for architectural comparisons; use real infrastructure for production SLO validation.

    Compute size count (16) is derived from the live size array in shared/provider-sizes.ts. Base compute rate ($0.096/hr) and base latency (45 ms) come from shared/provider-pricing.ts and shared/provider-config.ts respectively.

    Coverage snapshot version: 2026-06-28. This snapshot is validated against a 90-day freshness window in CI. To update, bump COVERAGE_VERSION in shared/provider-coverage.ts after reviewing pricing constants.
