Server Licensing Solutions for Your Business IT Infrastructure

We assess your existing or planned server infrastructure, operating systems, virtualization, users, devices and applications before recommending a licensing approach.

Licensing guidance and procurement support for Microsoft Windows Server environments, including applicable editions and licensing models.

Assess whether Standard licensing suits your physical server configuration and virtualization requirements.

Assess virtualization density, server hardware and infrastructure requirements to determine whether Datacenter licensing is appropriate.

Review user and device requirements to determine the relevant CAL requirements alongside server software licensing.

Review your virtualization platform, physical hosts, virtual machines and licensing program to develop an appropriate licensing structure.

Support procurement of required server software licenses, matching products, editions, quantities and licensing arrangements to the actual deployment.

Maintain visibility over server licenses, review upcoming renewals and support license lifecycle management as infrastructure changes.

Common for server operating systems such as Windows Server, where licensing is calculated against physical processors and cores rather than per server.

Relevant where licensing is tied to the number of users accessing a service, regardless of how many devices they use.

Relevant where licensing is tied to the number of devices accessing a service, useful where multiple users share a device.

A separate access license required alongside the underlying server software license, distinct from the software license itself.

A recurring licensing model, often tied to an active subscription term rather than a one-time purchase.

A one-time license purchase that may still apply for certain products or vendors, depending on what is currently offered.

Designed for lower virtualization density or non-virtualized environments — physical servers, file servers, application servers, domain controllers, smaller virtualization environments and branch-office infrastructure.

Intended for highly virtualized and software-defined datacenter environments. When licensed on the applicable physical-core model, it provides broader virtualization rights than Standard — suited to multiple Windows Server VMs, private cloud and large virtualization hosts.

Intended for smaller organizations and available through OEM channels. Microsoft describes the 2025 Essentials edition as suitable for small businesses with up to 25 users and 50 devices, subject to the current licensing program and product terms.

Associated with a specific user who requires access to licensed server environments — relevant where one employee accesses server resources from multiple devices.

Associated with a specific device accessing the server environment — relevant where multiple users share a common workstation or terminal.

Businesses using Windows Server Remote Desktop Services may require additional access licensing beyond the base Windows Server CAL.

Reviewing licensing before hardware is selected — Business Requirement → Server Architecture → Operating System → Virtualization → Licensing Model → Access Licensing → Deployment — to help reduce licensing surprises during implementation.

Reviewing licensing as businesses add servers, users, devices, virtual machines, branch offices and new applications over time.

Reviewing server licensing requirements across on-premises, private cloud, Azure and hybrid environments as part of broader cloud migration and modernization projects.

Deploying a first domain controller, file server, application server or virtualization host.

Adding servers, employees, applications or branch locations.

Managing larger physical and virtual server environments.

Operating server infrastructure across multiple offices.

Running multiple Windows Server virtual machines across virtualization hosts.

Combining on-premises infrastructure with cloud platforms.
