1. A method for operating cloud computing services in a cloud computing network comprising: collecting node status information, indicative of a configuration of a cloud computing node, from the cloud computing node, wherein the cloud computing node is connected to the cloud computing network; collecting cloud computing service status information indicative of an attribute of a cloud computing service being executed in the cloud computing node; collecting environmental data sets from a plurality of computing systems, each environmental data set corresponding to attribute values of one of the plurality of computing systems, wherein the computing systems are connected to a network which is connected to the cloud computing network; building a group of computing systems, wherein the group consists of computing systems of the plurality of computing systems with at least on identical attribute value; storing the node status information, the cloud service status information, the environmental data sets, and the identical attribute value of each computing system of the group of computing systems in a database; responsive to a request for characteristic data requested from one computing system of the group of computing systems, selecting the respective characteristic data out of the node status information, the cloud service status information, the cloud service status information and the environmental data sets in the database and sending the respective characteristic data over the cloud computing network and the network to the one computing system having requested the characteristic data; and responsive to a generate-new-service-request from one computing system belonging to the group, delivering of decision support data indicative of a best match between attributes of existing cloud computing services being executed in the cloud computing node and attributes of a new cloud computing service specified by the generate-new-service-request, wherein the existing cloud computing service is used by a computing system of the group, and wherein the best match may be determined by a highest number of identical attribute values between the specified attribute values and those of available cloud computing services.
