Azure’s licensing model provides flexibility, however it can be complicated resulting from a number of licensing options and pricing tiers.
There are several elements to consider when it involves Azure VM licensing:
– Operating System (OS) License: Typically, the working system, whether or not Windows Server, Linux, or a third-party OS, requires its own license.

2. Reserved Cases: For companies looking for a reduction in exchange for committing to a longer-term contract (usually 1 or 3 years), Azure provides Reserved Instances. This model provides significant savings on the base cost of a VM by locking in the value over the contract period. With Reserved Instances, you additionally pay for the VM license upfront.
Azure Hybrid Benefit
One of the important licensing options to understand is the Azure Hybrid Benefit, which can significantly reduce costs for businesses already utilizing Microsoft products, corresponding 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 allows users to carry their own licenses (BYOL), avoiding the necessity to purchase new licenses for Azure-based mostly VMs. The Azure Hybrid Benefit applies to each Windows Server and SQL Server, and it’s available for each Pay-As-You-Go and Reserved Occasion pricing models.
