A method for allocating fog applications in a fog network with a plurality of fog nodes is suggested. The method includes: providing an application model; providing a fog network image that reflects the properties of the fog network; performing a resource usage test of the application model on the fog network image, and receiving resource requirements for the fog network; creating a concrete application model based on the application model, wherein the concrete application model contains the received resource requirements; and performing allocation of the concrete application model on one or more of the fog nodes of the fog network.
