Abstract: In one example embodiment, a system comprises an event processing module accessible over a network; an event producer module associated with the event processing module and configured to monitor an action or directive of a consumer resource and, in response to a detected action or directive, generate an event and event metadata. The system further includes a conversion module associated with the event processing module and configured to acquire the event metadata and generate a generic event based on the acquired event metadata, and a transport module configured to distribute the generic event to a plurality of consumer resources.

Abstract: Techniques are described for updating a host operating system on a server while maintaining virtual machines running on the server. An updated host operating system is copied to the server. The currently active host operating system freezes the virtual machines but leaves them resident in RAM. The allocations and state for each virtual machine is copied to RAM or local storage. The active host operating system is shut down. Instead of issuing a command to reboot the server after it finishes shutting down, the active host operating system transfers execution to a loader. The loader reads the kernel of the updated host operating system into RAM along with an allocation map for the virtual machines and instructions to resume the virtual machines. The loader transfers execution to the updated host operating system entry point, and the updated host operating system loads the states of the virtual machines and resumes them.

Abstract: A proxy operating inside of a virtual machine that is responsible for receiving user-specified configuration information, such as credentials, and updating the configuration of the virtual machine with the user-specified values at the time of assigning the virtual machine to a user. Once the proxy updates the configuration of the virtual machine, the virtual machine is assigned the user that provided the user configuration information and the proxy can deactivate or uninstall itself from the virtual machine, such as by deleting all files, registry entries and other traces of execution.

Abstract: An approach is provided to apply a virtual machine (VM) image to a computer system. In the approach, implemented by an information handling system, a detection is made that a current VM image executing on the computer system is experiencing a problem. In response, prior VM images are analyzed, with each of the prior VM images being an image that was previously executed on the computer system. Based on the analysis, one of the prior VM images is selected and the selected image is used to replace the current VM image on the computer system.

Abstract: A technique for data de-duplication is applied to suspend and resume operations for virtual machines (VMs) to reduce the time needed to suspend or resume a virtual machine and store the suspended VMs in a space-efficient and time-efficient manner. A VM's state is serialized and written to disk in the form of key values that are used to retrieve data from a key-data map. The key-data map stores unique data blocks for suspended VM images. The key-data map can be stored in a solid-state drive to further reduce latency and access time.

Abstract: A method includes obtaining, by a processor, a representation of a first process and dividing the first process into tasks that make up the first process. The method includes determining relationships between the tasks and generating a task network comprising the tasks of the first process. The task network represents the relationships between the tasks of the first process. The method further includes receiving a priority criterion defining an objective and generating, based on the priority criterion, an optimal set of tasks in the task network to be performed.

Abstract: One embodiment of the present invention provides a system for provisioning physical resources shared by a plurality of jobs. During operation, the system establishes resource-usage models for the jobs, ranks the jobs based on quality of service (QoS) requirements associated with the jobs, and provisions the jobs for a predetermined time interval in such a way that any unused reservations associated with a first subset of jobs having higher QoS rankings are distributed to other remaining jobs with preference given to a second subset of jobs having a highest QoS ranking among the other remaining jobs. Provisioning the jobs involves making reservations for the jobs based on the resource-usage model and corresponding QoS requirements associated with the jobs.

Abstract: A system and method for autoscaling a multi-tier application, that has components executing on a plurality of tiers of a virtual data center, allocates resources to each of the plurality of tiers based on cost and performance. An application performance is determined, and a new application performance is estimated based at least partially on an application reservation and an application limit. An optimized utility of the application is calculated based on the cost to execute the application, the application reservation, and the application limit. A scaling factor for each tier is then determined to scale up or down a number of virtual machines operating in each of the tiers.

Abstract: Disclosed are various embodiments for a resource allocation application. Usage data for application program interfaces is aggregated over time. Limits for an allocation of resources for each of the application program interfaces are calculated as a function of the usage data. Limits are recalculated as new application program interfaces are added.

State information for certain of the one or more applications is saved and one or more applications are terminated in response to a memory condition. Subsequently, one of the terminated applications is revived using the saved state information.

Abstract: In mainframe computer system, workload tasks are accomplished using a logically partitioned data processing system, where the partitioned data processing system is divided into multiple logical partitions. In a system and method managing such a computer system, each running workload tasks that can be classified based on time criticality, and groups of logical partitions can be freely defined. Processing capacity limits for the logical partitions in a group of logical partitions based upon defined processing capacity thresholds and upon an iterative determination of how much capacity is needed for time critical workload tasks. Workload can be balanced between logical partitions within a group, to prevent surplus processing capacity being used to run not time critical workload on one logical partition when another logical partition running only time critical workload tasks faces processing deficit.

Abstract: A system, method and computer program product for allocating shared resources. Upon receiving requests for resources, the cost of bundling software in a virtual machine (VM) image is automatically generated. Software is selected by the cost for each bundle according to the time required to install it where required, offset by the time to uninstall it where not required. A number of VM images having the highest software bundle value (i.e., highest cost bundled) is selected and stored, e.g., in a machine image store. With subsequent requests for resources, VMs may be instantiated from one or more stored VM images and, further, stored images may be updated selectively updated with new images.

Abstract: An object-oriented software application is provided for receiving updates that change state of an object model and reporting those updates to requesting users. The application includes a database application for storing data; an object model driver for writing updates into the database; a notification system for notifying about the updates; and, a plurality of external monitors for reading the updates. In a preferred embodiment the object model produces multiple temporal snapshots of itself in co-currency with received events, each snapshot containing associated update information from an associated event and whereupon at the time of occurrence of each snapshot coinciding with an event the notification system notifies the appropriate external monitor or monitors, which in turn access the appropriate snapshot, performs calculations thereupon if required and renders the information accessible to the users.
