  • Patent number: 8839049
    Abstract: The present disclosure relates to dynamically allocating multitier applications based upon performance and reliability of resources. A controller analyzes resources and applications hosted by the resources, and collects operational data relating to the applications and resources. The controller is configured to determine an allocation scheme for allocating or reallocating the applications upon failure of a resource and/or upon rollout or distribution of a new application. The controller generates configuration data that describes steps for implementing the allocation scheme. The resources are monitored, in some embodiments, by monitoring devices. The monitoring devices collect and report the operational information and generate alarms if resources fail.

  • Patent number: 8626691
    Abstract: Methods, systems, and products answer questions using heuristics. A question and an input are received. A set of heuristic rules is retrieved, and the question is answered by evaluating an accuracy of each heuristic rule. Multiple accuracies from the set of heuristic rules are combined to produce a confidence level for the answer to the question.

  • Publication number: 20120102170
    Abstract: Methods, systems, and computer-readable media for providing collaborative quality of service (“QoS”) for service-oriented architectures are described. The application services in the service-oriented architecture implement a QoS application-programming interface (“API”) in addition to the traditional service API. The QoS API may include a QoS reporting interface for reporting values of QoS metrics of the application service, a QoS mechanism interface that exposes details of dependability mechanisms utilized by the application service, and/or a QoS negotiation interface that allows dynamic negotiation of what QoS properties the application service provides and how the QoS properties are provided. Service consumers may utilize the QoS API of the various application services in the service-oriented architecture to collect dependability information regarding the application services and make service provider selection decisions during discovery and dynamic binding.

  • Publication number: 20120102084
    Abstract: Network presence of a computing device in a cloud computing network is maintained while power consumption of the computing device is reduced. When the computing device is determined to enter an idle state, at least some of the operations of the computing device running in a virtual machine environment are migrated to a server within the cloud computing network while maintaining connectivity of the computing device to the cloud computing network. When the computing device is determined to be in the idle state, the computing device is put into a sleep mode to reduce power consumption of the computing device. When the computing device is determined to be in an active state, the computing device is woken, and the migrated operations are returned from the server to the computing device. This reduces power consumption of the computing device while maintaining the network presence of the computing device in the cloud computing network.

  • Patent number: 8073655
    Abstract: A method for measuring system response sensitivity, using live traffic and an analysis that converts randomly arriving stimuli and reactions to the stimuli to mean measures over chosen intervals, thereby creating periodically occurring samples that are processed. The system is perturbed in a chosen location of the system in a manner that is periodic with frequency p, and the system's response to arriving stimuli is measured at frequency p. The perturbation, illustratively, is with a square wave pattern.

  • Patent number: 7503286
    Abstract: A method of combusting oil shale in a circulating fluidized bed boiler. Fuel, including oil shale, is introduced into a furnace of the circulating fluidized bed boiler, primary oxygenous gas is introduced through a bottom grid of the furnace, and secondary oxygenous gas is introduced to the furnace at a first level above the level of the bottom grid. The primary oxygenous gas is introduced to the furnace at a rate providing below the first level a fluidizing velocity of less than 2.5 m/s, and the primary and secondary oxygenous gases are introduced to the furnace in such a way that a circulating fluidized bed is formed, and the fluidizing velocity at the first level is less than 70% of the fluidizing velocity in the upper portion of the furnace.
