In this scenario, purchasing DALs is a more cost effective solution.

In this case, we can purchase either 50 CAL licenses to cover the 50 users we have or alternatively 25 DAL licenses to cover the total amount of workstations that need to access the server.

We can use a simple example to help highlight the practical differences between CAL and DAL licensing models and understand the most cost-effective approach.Īssume an environment with Windows Server R2 standard edition and a total of 50 users and 25 devices workstations. Likewise, if a DAL is assigned to particular device, then any authenticated user using that device is allowed to access the server. The major difference between the Standard and Datacenter edition is that the Datacenter edition allows the creation of unlimited Virtual Machines and is therefore suitable for environments with extensive use of virtualization technology.īefore purchasing the Windows Server operating system, it is very important to understand the difference between various editions, the table below shows the difference between the four editions of Windows Server For example, a CAL assigned to a user, allows only that user to access the server via any device.
