摘要:
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.

A mechanism is provided for evaluating a service based on a request for the service. At least one attribute, having at least one preference parameter, is assigned to at least one generic configuration, the at least one generic configuration comprising at least one resource. A request is received for the service having an assigned quality-of-service-value, and a respective preference parameter value is assigned to each of the at least one preference parameters based on the quality-of-service-value. Furthermore, a combination of the resources is selected based on the request, the combination of the resources forming a selected configuration. Additionally, the selected configuration is mapped to one of the at least one of the generic configurations and the at least one preference parameter of the at least one attributes of the mapped at least one of the generic configurations is mapped to the selected configuration.

A computer-implemented method of enabling security in network resources provisioned as part of a service landscape instance is provided. The method includes initiating an orchestration process for creating a landscape service instance to provide services to a service subscriber over a data communications network. The method further includes deriving from the orchestration process at least one parameter, and generating at least one security configuration profile based upon the at least one parameter for at least one system of the landscape service instance.

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.

摘要:
A system for provisioning service environments (SEs) and resources includes a component for creating and handling state change events and a parts catalog including descriptions of SEs, variable federated resources, aggregated, and basic resources. The system further includes a planner component for generating plans for construction and destruction of SEs and plans for creation, addition, removal and destruction of every aggregated resource to or from the SEs. The planner component has an interface to the parts catalog and an interface to a global dynamic free pool manager. The global dynamic free pool manager is configured for dynamically constructing and destructing dynamic free pool managers with their assigned dynamic free pools including dynamically changing their capacities.
摘要:
The idea of the present invention is to provide a method for automatically transforming a provider offering describing a customer specific service environment in business terms into a machine readable form which can be automatically processed by resource management systems. The input for the transformation is the provider's offering in business terms as well information from the resource catalog. The result of the transformation is a customer specific service environment topology that states all the necessary resource types, their configurations and their dependencies. Based on that customer specific service environment topology and information from the resource management catalog, a customer specific service environment definition (SED) is automatically generated which contains all the configuration information and definitions of the resource management actions in order to instantiate and drive the operation of the service environment. The SED can be deployed into a resource management system that automatically executes the resource management actions without the error prone configuration steps otherwise needed.

The present invention provides a system, method, and computer program product to accelerate provisioning by dynamically creating dynamic free pools (DFPs) of pre-provisioned resources that are provisioned in advance, and are ready and free for use. A DFP construct for a resource, and its associated dynamic free pool manager are generated dynamically from a formal description of an aggregated resource structure (e.g. in the form of an XML schema). The present invention also provides a system, method, and computer program product to improve the delivery time of SEs based on the DFP constructs. The methods are extended to deal with special conditions such as contention over resources, or critical delivery time.
