[Open Data] Update instance size flexibility ratios (October 2026)

[Roland Krummenacher (RolandKrummenacher)]

Summary

Weekly automated update of instance size flexibility (ISF) ratios from the
Azure Reservations Catalogs API,
produced by the Update Instance Size Flexibility workflow (run 38213176611).

Change

23 added rows, no rows modified or removed:

ISF group	SKUs	Ratios
Virtual Machines Laosv5-series Linux	12	1 (L2aos_v5) to 80 (L160iaos_v5)
Virtual Machines Lasv5-series Linux	11	1 (L2as_v5) to 80 (L160ias_v5)

Both are new groups. Every ratio equals the SKU's vCPU count divided by 2, consistent with the base size of 2 vCPUs.

Notes

This is the first run after #2331, which sorts the output ordinally. The 21 September, 28 September, and 5 October branches each carried the same 247-line reorder churn on top of their real changes; this branch has only the 23 real rows. Those three branches are superseded and have been deleted.

The branch was cut before #2298 added the generated PowerShell open data files to dev, so the Open Data CI's regeneration commit re-added them and caused add/add conflicts. dev has been merged in: three of the files were identical, and Get-OpenDataInstanceSizeFlexibility.ps1 keeps the branch side, which is the dev version plus the 23 new rows. The diff against dev is now only InstanceSizeFlexibility.csv (+23) and Get-OpenDataInstanceSizeFlexibility.ps1 (+23).

Test plan

• Open Data CI passes
• Reviewed the diff: 23 added lines in the CSV and 23 in the generated PowerShell file, no rows modified or removed
• Get-OpenDataInstanceSizeFlexibility and Get-FinOpsInstanceSizeFlexibility unit tests pass locally
• Spot-check a Laosv5 and a Lasv5 SKU against the Azure Pricing Calculator

🟡 Changes recommended

The branch must merge dev and resolve its add/add conflicts so only the intended ISF updates remain.
