RDS CAL Licensing Options

Benefits of User CALs

User CALs are designed for organizations where employees need to access the server environment from multiple locations and devices.

  • Multi-Device Flexibility: Ideal for individuals who need to access the server from a laptop at the office, a desktop at home, and mobile devices while traveling.
  • Simplified Management: One license covers a single user regardless of how many devices they use to connect.
  • Mobile Workforce Support: Best suited for modern remote work environments and flexible staff schedules.

Benefits of Device CALs

Device CALs are the preferred choice for specific business models where multiple employees utilize the same hardware.

  • Shared Workstation Efficiency: Perfect for shift-work environments, call centers, or retail points-of-sale where several users connect through a single machine.
  • Lab & Kiosk Environments: Highly cost-effective for training labs or public-access kiosks where the user-to-device ratio is high.
  • Budget Optimization: Allows organizations to choose the model that best fits their specific workflow and hardware setup.

Frequently Asked Questions

How do I choose between User CALs and Device CALs?

The easiest rule of thumb is to count your users and your devices, then license whichever number is smaller:

  • Choose RDS User CALs if your employees work from multiple devices (e.g., a laptop, smartphone, and home PC). One User CAL covers one specific person across all their devices.
  • Choose RDS Device CALs if multiple people share a single workstation (e.g., shift workers, call centers, or lab kiosks). One Device CAL covers one specific machine, regardless of how many users log into it.
