Cross-Vendor Multi-Node Spot Instance Dynamics: A Public Cloud Data Archive Service and Analysis

Reproducibility artifact for "Cross-Vendor Multi-Node Spot Instance Dynamics: A Public Cloud Data Archive Service and Analysis" (Future Generation Computer Systems). The archive (spotlake-fgcs-artifact.zip) is fully self-contained: every published table and figure regenerates from the bundled code and data, with no external service, cloud credential, or network access required, and the regenerated figures are byte-identical to those in the revised manuscript. Layout: code/ (figure and table scripts, preprocessing provenance, revision analyses), data/ (canonical aggregates over the corrected representative regions; frozen submitted-era inputs with pinned sha256; derived validation tables; June 2025 same-cycle and pre-merge reference query streams; raw logs of the 2026 provisioning experiments; the sole surviving copy of the January 2024 AWS target-capacity probe; archived June 2025 vendor IP-range snapshots), and output/ (reference renders). See README.md for the regeneration map, data policy, and value-handling rules. The SpotLake archive service is public at https://spotlake.ddps.cloud/ and the collection system is open source at https://github.com/ddps-lab/spotlake. Code: MIT license; data: CC BY 4.0.
