Comparing Microsoft Remote Desktop 2012 R2 vs 2019 CALs
Choosing between Microsoft Remote Desktop 2012 R2 vs 2019 CALs requires understanding licensing models, compatibility, and cost implications.
CALs grant authorized access for users or devices to utilize RDS functionality on a Microsoft Server.
Types of RDS CALs: Device vs User Licensing
Device CALs license each device accessing the Remote Desktop Services regardless of the number of users logging in on that device.
User CALs license each user who uses the RDS environment, allowing them to connect from multiple devices.
Both 2012 R2 and 2019 support these CAL types.
The choice depends on your organizational needs.
For example, a user with multiple devices benefits from a User CAL, while a shared workstation environment favors Device CALs.
Both versions maintain the same fundamental licensing structure with increased compliance focus in 2019.
Microsoft offers two main types of Remote Desktop Services (RDS) Client Access Licenses (CALs): Per Device CALs and Per User CALs.
– Per Device CALs are assigned to individual devices. When a device accesses a Remote Desktop session for the first time, a temporary CAL is issued and then upgraded to a full CAL by the license server. This model suits environments where multiple users share a limited number of devices, such as shift workers using the same workstations on different shifts.
– Per User CALs are assigned to individual users. Each user can access the Remote Desktop services from any device. This model works best where users have their own dedicated devices and need to access sessions from multiple locations or devices.
Both CAL types require that the CAL version matches or exceeds the server version and are specifically required for remote desktop access. Licensing allows reassignment of CALs when users leave or devices are retired.
Cost and Licensing Flexibility Comparison
Cost differs mainly due to expanded features and security in the 2019 CALs, often reflected in a slightly higher price point compared to 2012 R2.
Licensing flexibility improved in 2019, supporting larger teams and easy scaling, especially for educational institutions and growing businesses.
Volume licensing agreements and Software Assurance options offer potential savings and upgrade pathways.
In contrast, 2012 R2 CALs might be more cost-effective for small teams with stable infrastructure needs.
However, long term support and security upgrades favor the investment in 2019 CALs.
Windows Server 2012 vs 2019 RDS: Performance and Usability Comparison
When comparing Windows Server 2012 vs 2019 RDS performance and usability, the 2019 version clearly pushes forward enhancements that benefit heavy workloads and user experience.
Performance Improvements in Windows Server 2019
The 2019 RDS includes substantial improvements in connection handling, reducing reconnection times and improving session reliability.
