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.
