SQL Server Device CAL

Description

SQL Server Device CAL

The Server + CAL licensing architecture for Microsoft SQL Server necessitates the use of a SQL Server Device CAL (Device Access License). which is a sort of license. It gives  the devices authority to access a SQL Server instance from any device that they use.

Important information regarding SQL Server Device Access Licenses (CALs):

Device-centric:

A Device Access License (CAL) is granted to a particular device. This enables that device to establish a connection to the SQL Server from a number of different devices. Such examples are a computer at work, a computer at home, or a mobile device.

Right of access:

It is not the software itself, but rather a license that grants a device the ability to get access to and interact with the SQL Server software.

Server + CAL model:

The Server + CAL licensing model is one in which you purchase licenses for both the SQL Server and the devices that access it.   Device CALs are included as part of this model. The Structured Query Language Server Standard Edition is the primary distribution method for this architecture.

Device CAL as an Alternative to User CAL:

A User CAL is a type of licensing that allows a single user to access the server from many devices. This is in contrast to a Device CAL, which licenses a specific device for access by multiple users. A device CAL is advantageous when devices need to access the server from a variety of locations, or when the number of devices is more than the number of users.

Indirect access:

Devices are still required to have a Device Access License (CAL) even if they only access the SQL Server indirectly, through another application or hardware device.

Considerations pertaining to the expense:

Device Client Access Licenses (Device CALs) might be a cost-effective option when the number of devices is relatively small. These licenses are necessary when devices need to access the server from different locations. When it comes to environments that have a high number of devices, such as those that view web pages, the Per-Core licensing model, which does not necessitate the purchase of Device Access Licenses (CALs), is frequently a better fit.
