- 16 cores per server.
3. Azure Hybrid Benefit
- Allows you to reuse existing licenses on Azure virtual machines.
- Reduces operating costs in hybrid environments.
- It offers complete flexibility between cloud and on-premises infrastructure.
4. Licensing for Virtual Environments
- Based on virtual cores (vCores).
- Requires a minimum of 8 licenses per virtual machine.
- It provides cost predictability and simplifies the management of virtualized environments.
5. Windows Server CALs (Client Access Licenses)

Impacts of the new licensing for companies
With the changes in Windows Server 2025 licensing, As companies gain more autonomy, they also need careful planning.
Here are the key points:
- More flexibility with the pay-as-you-go model, ideal for scaling operations.
- Reducing initial costs and resource optimization.
- Greater compliance control through core licensing.
- Seamless integration with Azure, taking advantage of hybrid benefits.
- Pay attention to CALs., essential to avoid legal and audit problems.
How to ensure compliance and optimize licensing costs.
- Make one complete inventory of servers and cores in use.
- Use the Azure Hybrid Benefit to take advantage of existing licenses.
- Evaluate the model pay-as-you-go before migrating to the new system.
- Monitor the use of CALs and keep documentation up to date.
- Consider tools for software asset management (SAM) for audits and continuous optimization.
