Can Azure Hybrid Benefit be combined with Reservations for extra savings?

Yes — Azure Hybrid Benefit (applying existing on-premises Windows Server/SQL Server licenses) and Reservations (committing to usage for a discount) are independent discount mechanisms that can be combined, often resulting in substantially lower effective costs than using either alone.

This combination is one of the more significant cost optimization levers available for organizations that already own eligible on-premises licenses and are running predictable workloads in Azure.
