摘要:
The inventive process for modeling workflows for interacting stateful resources starts with modeling an activity sequence description (ASD) by using keywords. The keywords specify well-defined resource-interaction semantics. Each modification of the ASD automatically triggers a new checking process of the ASD in its current state which is executed by the ASD processor. The ASD processor parses the keyword, evaluates the resource-interaction semantic associated with the keyword, and creates for each modeled activity an updated resource type model and an updated resource instance model based on the information provided by the current resource type model, the current resource instance model, the semantics associated the currently processed keyword and the semantics of the relationship stereotype definition. The present invention allows modeling of the workflow with the underlying resources at the same time by using the keywords and ensures consistency between the workflows and the underlying resource model already during the modeling process.

A data processing method is disclosed. The data processing method comprises the step of receiving a request for a service interface description of a service from a client at a server, wherein the service is implemented via a first service endpoint at the server, and wherein the first service endpoint is associated with a first service endpoint interface description. In a further step, a given set of correlations is employed for the determination of service endpoints correlated with the first service endpoint with respect to the service, wherein each of the correlated service endpoints is associated with a service endpoint interface description. Furthermore the service interface description is generated by aggregating the first service endpoint interface description with the service endpoint interface descriptions of the correlated service endpoints and the service interface description is provided to the client.

A method of collecting usage data of an on-demand service provided to a subscriber is disclosed. The method comprises provisioning of a first manageable resource in order to provide the on-demand service to the subscriber, the first manageable resource being associated with at least a first underlying resource, the first underlying resource comprising a first collector for collecting first usage data of the first underlying resource while the on-demand service is provided. Further, a first metering component is instantiated for the first manageable resource and the first metering component is instructed to initiate the retrieval of the first usage data from the first collector prior to the termination of the first metering component and the de-provisioning of the first manageable resource. Additionally, the retrieved first usage data is stored for further evaluation.

Deploying a software service. A defined software service offering is selected from a plurality of defined software service offerings. An instantiation order for deploying the selected defined software service offering on a corresponding computer system is generated. Each defined software service offering comprises a software service definition and at least one defined software policy. One selected from the group consisting of the software service definition, the software policy, and a combination thereof, provides a hardware configuration for the software service, a software configuration for the software service, and a managing policy for the software service. The instantiation order of the software service for execution on the computer system is created based on the hardware configuration, the software configuration and the managing policy.

A computer-implemented method is provided for updating network security policy rules when network resources are provisioned in a service landscape instance. The method includes categorizing network resources in a service landscape instance based on a service landscape model. The method further includes responding to the provisioning of a network resource by automatically generating one or more security policy rules for a newly-provisioned network resource. Additionally, the method includes updating security policy rules of pre-existing network resources in the service landscape instance that are determined to be eligible to communicate with the newly-provisioned network resource so as to include the newly-provisioned network resource as a remote resource based on the service landscape model.

A method for migrating virtual machines between hypervisors is disclosed. Initially, metadata describing a virtual machine are automatically scanned and parsed. The structure of the metadata of a source virtual machine are automatically analyzed. Elements of this structure are mapped to corresponding entries of a target virtual machine. A target metadata descriptor to be used as part of the target virtual machine is generated. A predefined layout description of the data stored in a file system image of the source virtual machine read. A predefined layout description of the data to be stored in a file system image to be used at the target virtual machine is also read. The data are extracted from the source virtual machine. A template of a file system image for the target virtual system is generated. Storage space corresponding to the target virtual machine is allocated, and the extracted data are inserted into the allocated storage space.

Method, computer program products and systems for conserving energy in data processing center, wherein a plurality of services are offered to a plurality of subscribed service consumers in a dynamic fashion, allowing a created service instance to be re-assigned from one to another server of the resources. Control parameters comprising power consumption and temperature of a group of resources are monitored. A workload may be assigned properties such as “hot” and “cold.” which are then assessed. A hot workload may be relocated to a cold spot, and if necessary, a cold workload may be relocated to a location which was de-loaded from a workload, that is, a hot spot, which is then considered to cool down due to addition of less workload in form of the cold workload. Thus, the energy required to cool the data center may be minimized.
