What are access licenses (CAL)?

Access licenses, also known as Client Access Licenses (CAL), are special licenses that allow users to access server services. These licenses are required when multiple users or devices want to access a server to ensure that the software is used legally. CALs are available in various versions to meet different requirements and are an important part of licensing Microsoft server products.

What types of access licenses are there?

There are two main types of access licenses: user CALs and device CALs. User CALs are intended for individual users who access the server from various devices. Device CALs, on the other hand, are licensed for specific devices that can be used by multiple users. The choice between these two types depends on your company's specific usage and requirements.

How do I choose the right CAL for my company?

The choice of the right CAL depends on your company's structure and the type of usage. If your employees frequently switch between different devices, user CALs may be the better choice. Conversely, if fixed workstations with multiple users exist, device CALs could be more cost-efficient. A careful analysis of usage patterns helps you determine the appropriate license type.

What should I consider when licensing?

When licensing access licenses, you should ensure that you correctly estimate the number of licenses needed. It is important to consider the licensing requirements for all users and devices that want to access the server. Additionally, you should observe Microsoft's licensing terms and policies to ensure compliance with all legal requirements.

• User CALs for flexible access from different devices
• Device CALs for multiple users at a fixed workstation
• Assessment of the number of licenses for lawful access

How do I acquire access licenses?

Access licenses can be purchased through authorized Microsoft resellers or directly via the Microsoft website. It is advisable to inform yourself about the different licensing models and their prices before purchasing. Additionally, consider the option of acquiring volume licenses if your company requires a larger number of licenses, as this is often more cost-effective.

How do CALs differ from other licensing models?

Access licenses differ from other licensing models because they are specifically designed for accessing server services. Unlike traditional software licenses, which are often tied to a single device, CALs allow access for multiple users or devices. This flexibility is especially beneficial for companies with a dynamic work environment and varying access needs.

What system requirements apply to CALs?

Access licenses themselves have no specific system requirements, as they are not software that needs to be installed. However, the servers being accessed must meet the corresponding system requirements to use the CALs. Ensure that the server environment is properly configured to guarantee smooth access for all licensed users or devices.
