Reserved Instances and Azure Hybrid Benefit
Cut compute costs by committing to one- or three-year Reserved VM Instances, and apply the Azure Hybrid Benefit to reuse existing Windows Server and SQL Server licences.
Introduction to Azure Reservations
Azure Reservations are one- or three-year commitments to specific Azure resource configurations in exchange for significant discounts compared to pay-as-you-go pricing. Reservations are paid upfront or monthly, and the discount is automatically applied to any matching resource you have running — you do not need to change anything about how you deploy the resources. Reservations are the primary cost optimisation tool for stable, predictable workloads.
Reserved Virtual Machine Instances
Reserved VM Instances (RVIs) provide up to 72% savings over pay-as-you-go VM pricing. When you purchase an RVI, you specify the VM series (e.g., D-series v5), region (e.g., East US), and OS (Windows or Linux). Azure automatically applies the reservation discount to any running VM of that specification during the reservation term. You can choose instance size flexibility to allow the discount to apply across different sizes within the same VM family.
