Sysprobs Data: prices, licences and surveys you can check
Original datasets, calculators and reference tables for IT infrastructure. Every figure is traced to a primary source, dated and refreshed on a schedule.
Source: Sysprobs Data, derived from vendor pricing pages and archived snapshots; formula and every candidate model in the methodology. Dashed segments cross quarters with no readable snapshot. Prices more than 24 months old are marked dated.
Standard or Datacenter? Move the slider.

Open the full calculator for other host sizes and Azure Arc pricing, or read the data and methodology.
Microsoft suggested prices per 16-core pack: Standard $1,176, Datacenter $6,771. Licences only.
