Windows Server licensing for businesses
Licensed Windows Server for Business
IT Systems helps businesses choose Windows Server Standard, Datacenter, User CAL, Device CAL and RDS CAL based on file server, domain controller, internal application or virtualization needs.
Choose by server model
Standard
Suitable for physical servers or environments with limited virtualization requirements.
Datacenter
Suitable for infrastructure with many virtual machines and broader virtualization rights.
CAL and RDS CAL
Plan user/device access licenses and Remote Desktop Services CAL separately when required.
Common Windows Server use cases
Domain Controller
Manage users, login policies, computers, groups and access permissions across the business network.
File and application server
Host shared data, folder permissions, accounting software, ERP systems or internal business applications.
Virtualization infrastructure
Run multiple workloads on Hyper-V or other virtualization platforms and plan licensing by core and VM rights.
CAL planning
Estimate Windows Server CAL by user or device and add RDS CAL when users access Remote Desktop or terminal services.
