Abstract: Method for controlling first and second resources in a system including first and second components managing the first and second resources, respectively and at least one host hosting the second resource in a cloud environment, one of the first and second components comprises a compute component and the other comprises a storage component, one of the first and second resources is a compute resource and the other is a storage resource, the method comprising: causing the first component to send an inquiry request including an inquiry relating to the second resource, to the second component; causing the second component to send an inquiry response including information on the at least one host, to the first component; causing the co-location of the first and second resources on a single host that is either the at least one host or a further host hosting the first resource, based on the inquiry response.

Abstract: In general, it is proposed to define techniques for managing a virtual storage volume in a cloud architecture comprising hosts which provide storage volume. The managing is achieved by checking the available virtual storage volume when a storage service request from a request interface is received. The virtual storage volume comprises at least one storage volume being assigned to the virtual storage volume. In case the storage service request can not be fulfilled by the available virtual storage volume, a request to the request interface is sent for requesting additional storage volume directly from at least one host. Upon receipt of an accept message that a storage volume fulfilling the storage service is exiting and available, the request interface initiates assigning of the additional storage volume to the virtual storage volume. As next the storage service request is executed on the virtual storage volume.

Abstract: Control data is loaded for each one of a plurality of software code items. The control data is indicative of a time-dependent allocation of computational resources when performing an integrity test of the respective software code item. Based on the control data, test hardware is triggered to perform the integrity tests in a time-parallelized manner.

Abstract: The present invention relates to a method for running a virtual machine on a destination host node in a computer cluster, comprising the steps of requesting (S101) a set of target configuration parameters assigned to the virtual machine, wherein the target configuration parameters have prioritizations; requesting (S102) a set of actual configuration parameters of the destination host node for checking against the requested set of target configuration parameters; and running (S103) the virtual machine on the destination host node, if the set of actual configuration parameters of the destination host node falls within the set of target configuration parameters, wherein when selecting destination host node, the prioritization of the target configuration parameters is considered.
