CAL stands for “Client Access License.” It is a license that grants users or devices the right to access the services or features of a server. CALs are particularly relevant in the context of Microsoft server products such as Microsoft Windows Server, SQL Server, Exchange Server, and many others.
Der er to hovedtyper af CAL'er:
- Bruger-CAL'er: Denne type licens giver en bestemt bruger ret til at få adgang til serveren fra en hvilken som helst enhed (f.eks. en arbejdsstation, hjemme-pc, smartphone osv.).
- Enhed CALs: Denne type licens giver en bestemt enhed ret til at blive brugt af enhver bruger til at få adgang til serveren. Denne mulighed kan være mere omkostningseffektiv, når flere brugere bruger den samme arbejdsstation eller enhed til at få adgang til serveren.
The choice between User CALs and Device CALs depends on the specific usage scenario in a company or organization. Microsoft offers these flexible licensing options to accommodate different business models and work practices.
CALs are necessary because Microsoft’s server operating systems and some other server products are licensed based on the principle of access licenses. This means that, in addition to the license for the server itself, additional licenses are required to legalize access to that server.
