Please be aware Microsoft have advised that as of January 2023, upfront margin will no longer be offered on Azure Reserved Instances. This means that moving forward the cost you see for Reservations purchased will be the same as the RRP. Other related incentives will be unchanged. Any Reserved Instanced provisioned prior to January 2023 will not be affected by this change, although the new pricing structure will be applied after their term concludes and at the time of renewal.
For more information on this change please see this collection in the Microsoft partner portal:
