Apr 1, 2025

April 2025 performance summary for RunPod integrations across catalog and core. Delivered two key RunPod enhancements that improve location data fidelity and deployment granularity: - Catalog enrichment: Added an AvailabilityZone column to vms.csv and populated zone identifiers across regions and instance types (RunPod zones). Committed in 9968eb1766e5561c36ddc5589fabdcf9ed33ec45 (Add RunPod zones #115). - Zone-aware provisioning: Enabled zone-specific provisioning by treating a data center ID as the region and allowing explicit zone specification for RunPod deployments. Committed in 53ae87f3026d2976b0e7d4b860879e84ed067495 ([RunPod] Use zone to provision in a specific data center ID #5166).
