A financial enterprise is performing a Total Cost of Ownership (TCO) evaluation before migrating a core enterprise workload to Azure Virtual Machines. The workload requires continuous compute capacity operating 24 hours a day, 7 days a week, with predictable resource demand for the next three years.
Which pricing model should the enterprise select to achieve the lowest long-term operational costs?

Azure Reservations (such as Azure Reserved Virtual Machine Instances) provide significant billing discounts compared to standard pay-as-you-go rates when an organization commits to a one-year or three-year term for specific cloud resources.
In a Total Cost of Ownership (TCO) evaluation, stable and continuous 24/7 workloads incur high cumulative operational expenditures (OpEx) if billed on an hourly pay-as-you-go basis. By committing to a three-year reservation term, the organization substantially lowers its unit cost for compute capacity, yielding maximum long-term financial savings without sacrificing operational continuity or workload stability.
For steady-state, non-interrupted production environments with known capacity demands over multiple years, Azure Reservations offer the optimal balance of steep cost reduction and guaranteed resource availability compared to uncommitted or interruptible models.
