Microsoft Cloud for Healthcare adds cloud services to support healthcare scenarios for customers already licensed for Microsoft 365 and/or Dynamics 365.
At its launch in November 2020 it was licensed via User SLs, but from 1 April, 2022 it will move to a per tenant licensing model costing $20,000 per month.
