Understanding Microsoft Host Integration Server Licensing

Microsoft offers two main licensing models for Host Integration Server: Server/CAL and Core-based. Both models have their own advantages and limitations, and it is important to understand them before making a decision.

Server/CAL Licensing Model

The Server/CAL licensing model requires the purchase of a server license for each instance of Host Integration Server running on a physical or virtual machine. In addition, Client Access Licenses (CALs) must be purchased for each user or device that accesses Host Integration Server.

This licensing model is ideal for organizations with a fixed number of users or devices accessing Host Integration Server, as it provides a predictable and scalable licensing structure.

Core-based Licensing Model

The Core-based licensing model is based on the number of cores on the physical server or virtual machine running Host Integration Server. It requires the purchase of a minimum of 8 core licenses per physical processor, and a minimum of 16 core licenses per server for virtual machines.

This licensing model is ideal for organizations with a variable number of users or devices accessing Host Integration Server, or for those who require a more flexible licensing structure. However, it can be more complex and expensive to manage compared to the Server/CAL model.

Microsoft Host Integration Server Licensing FAQ

Q: How do I determine which licensing model to use for my organization?

A: The choice of licensing model depends on several factors, including the number of users or devices accessing Host Integration Server, the number of physical servers or virtual machines running Host Integration Server, and the overall budget for licensing. It is recommended to consult with a licensing specialist or a Microsoft representative to determine which model is the best fit for your organization.

Q: Can I switch between licensing models?

A: Yes, it is possible to switch between the Server/CAL and Core-based licensing models. However, it is important to note that the switch can only be made at the time of license renewal.

Q: Are there any other licensing options for Microsoft Host Integration Server?

A: Yes, Microsoft also offers Azure Hybrid Benefit for Host Integration Server, which allows organizations to use their existing Host Integration Server licenses on Azure virtual machines. This can provide cost savings and flexibility for organizations looking to migrate their legacy systems to the cloud.

Conclusion

Choosing the right licensing model for Microsoft Host Integration Server is a critical decision for any organization. It is important to understand the advantages and limitations of each model, and to consult with licensing specialists or Microsoft representatives to determine the best fit for your organization.
