# Azure Hybrid Benefit Not Enabled on Virtual Machines

## Explanation

Many organizations purchase Software Assurance or subscription-based Windows and SQL Server licenses that entitle them to use Azure Hybrid Benefit. However, if the setting is not applied on eligible resources, Azure continues charging pay-as-you-go rates that already include Microsoft licensing costs. This oversight results in paying twice-once for the on-premises license and once for the built-in Azure license. The inefficiency often goes unnoticed because licensing configurations are not centrally validated or enforced. Enabling AHUB can reduce costs by up to 40% for Windows server VMs and up to 30% for SQL Databases.

## Relevant Billing Model

Azure bills Windows and SQL-based VMs either as license-inclusive (pay-as-you-go) or license-excluded (when Azure Hybrid Benefit is applied). Without AHB enabled, workloads that already own valid licenses are billed at the higher license-inclusive rate, resulting in duplicated spend.

## Detection

- Review all Windows and SQL Server virtual machines to determine if Azure Hybrid Benefit is enabled in their configuration

- Correlate VM licensing status with internal Software Assurance or Microsoft volume license records to confirm eligibility

- Evaluate the proportion of eligible VMs still billed at license-inclusive (pay-as-you-go) rates

- Check whether governance policies exist to enforce AHB application during provisioning

## Remediation

- Enable Azure Hybrid Benefit for all eligible Windows and SQL-based VMs to apply owned licenses and reduce compute costs

- Implement Azure Policy or blueprints to automatically enforce AHB for future deployments where eligibility applies

- Maintain an up-to-date inventory of licensed assets and ensure license entitlements align with deployed resources

- Regularly review licensing configuration compliance across subscriptions to prevent recurrence
