2. Reserved Cases: For companies looking for a discount in exchange for committing to a longer-term contract (normally 1 or three years), Azure gives Reserved Instances. This model provides significant financial savings on the bottom cost of a VM by locking within the value over the contract period. With Reserved Cases, you additionally pay for the VM license upfront.

Azure Hybrid Benefit

Probably the most vital licensing options to understand is the Azure Hybrid Benefit, which can significantly reduce costs for businesses already utilizing Microsoft products, comparable to Windows Server and SQL Server, under existing Software Assurance or qualifying subscriptions.

With the Azure Hybrid Benefit, businesses can reuse their on-premises licenses for virtual machines in the cloud. This permits customers to convey their own licenses (BYOL), avoiding the need to buy new licenses for Azure-primarily based VMs. The Azure Hybrid Benefit applies to both Windows Server and SQL Server, and it’s available for each Pay-As-You-Go and Reserved Occasion pricing models.

Types of Azure VM Licenses
