1. A method for connecting an end device to a linkable computer infrastructure, the method comprising:
creating a device certificate and supplying the created device certificate to a user of the end device;
inputting the created device certificate into the end device;
producing a data link from the end device to an access zone connected upstream of functions of the linkable computer infrastructure, the access zone being selectively separable from the functions of the linkable computer infrastructure by the data link, wherein a cloud service is used as the linkable computer infrastructure and wherein the access zone is a demilitarized zone;
registering the end device in the access zone using the created device certificate;
identifying the end device for the linkable computer infrastructure by access of a function from the linkable computer infrastructure to the end device registered in the access zone;
accessing, by an access zone management, the end device registered in the access zone as a function of the linkable computer infrastructure;
identifying the end device, enabling the end device for use of the linkable computer infrastructure by the access zone management, or a combination thereof,
enabling use of the linkable computer infrastructure for the end device in response to successful identification of the end device;
supplying a plurality of user spaces assigned to different users, respectively, in the linkable computer infrastructure;
identifying the end device registered in the access zone by access of a function from a corresponding user space of the linkable computer infrastructure;
allocating, by the access zone management, the end device a use token for the corresponding user space of the linkable computer infrastructure; and
granting the end device access to the function of the corresponding user space by the allocation of the use token.
