Abstract: A computer-implemented method for metadata-based retention of personal data may be provided. The method comprises recording data by a recording system. The data comprise payload data and metadata comprising information about the payload data and an event type; and a rule is associated with the event type, wherein the rule is indicative whether the data shall be stored persistently or temporary. The method comprises further segmenting the recorded data into a plurality of non-overlapping data segments, encrypting each data segment of the plurality of non-overlapping data segments with a unique key each, transmitting the encrypted data segments wirelessly, and storing, using a secure service container, selected ones of the plurality of non-overlapping data segments as a function of the rule.

Abstract: A method for accessing non-functional host capabilities and services of a host operating system, by a guest operating system, is provided. The method includes receiving a function code and additional data from an application of a guest operating system, wherein the function code corresponds to a non-functional service request on a host operating system. The method further includes creating a parameter control block using the function code and the additional data in memory of the guest operating system, wherein the parameter control block is accessible by a hypervisor of the host operating system. The method further includes issuing a hardware instruction by the guest operating system, wherein the hypervisor of the host operating system receives control. The method further includes receiving a notification from the hypervisor that the execution of the non-functional service request is complete.

Abstract: A method for enhancing a workload manager for a computer system includes sampling and storing usage of a resource of the computer system as resource usage values, comparing said resource usage values with predetermined performance goal values, assigning a time-stamped priority value to an application that is running based on at least one of the performance goal values by the workload manager, retrieving a portion of the resource usage values and a related portion of the performance goal values for the application, identifying a future workload demand value by applying a time-series analysis algorithm to the resource usage values and the performance goal values for the application resulting in workload demand time frames and related amplitudes of the workload demand time frames, and adjusting a dispatch priority value for the application by setting a minimum dispatch priority for the application based on the future workload demand value.

Abstract: Performance predictions in a computing cluster can be provided by sampling and storing historic workload request data of the computing cluster as time-stamped workload values, forecasting an expected total number of workload requests for a defined time interval in the future based on a time-series analysis of the time-stamped workload values, where the time-series analysis detects cyclic and repeating events in the time-stamped workload values. In response to a result of the time-series analysis, training a workload prediction model by using additional data about acyclic events in expected workload requests, where the training applies a statistical regression technique for predicting a future workload demand for the computing cluster, and in response to exceeding a predefined threshold value of the predicted future workload demand, reassigning resources of the computing cluster.

Abstract: A method, computer program product, and system includes a processor(s) in a first computing environment obtaining, from a computer system in the first environment, a system message indicating an issue in the computer system. The processor(s) evaluate the message to determine details of the issue and determine recommended action(s) to remedy the issue. The processor(s) generate a notification comprising the action(s), which include calls to portions of the computer system and the notification comprises respective selection options to trigger the processor(s) to execute each of the one or more recommended actions in the first environment. The processor(s) transmit the notification to a computing node in a second computing environment to communicate to a computing device in that environment. The processor(s) receive a response indicating selection of a respective selection option. The processor(s) translate the option into a recommended action and issue calls in the recommended action to the computer system.

Abstract: Provided is a method for determining a target host from a plurality of candidate hosts for migrating a software container. A management software component may instantiate a source agent software component on a source host and a target agent software component on each of a plurality of candidate target hosts. Resource requirements of at least one software container may be determined by the source agent software component. Resource capabilities of each of a plurality of target hosts may be determined by the target agent software components. The source agent software component may compare the resource requirements to the resource capabilities of each of the plurality of candidate target hosts. If the resource requirements are satisfied by a particular candidate target host, the particular candidate target host is assigned to be a target host. The at least one software container is migrated from the source host to the target host.

Abstract: In one embodiment, in accordance with the present invention, a method, computer program product, and system for accessing non-functional host capabilities and services of a host operating system, by a guest operating system, are provided. The method includes a hypervisor, of a host OS, intercepting a hardware instruction from a guest operating system, wherein the hardware instruction is associated with data located in a register and in memory that is accessible by the hypervisor. The method further includes analyzing the hardware instruction and data to determine if the hardware instruction is a non-functional service request. The method further includes, upon determining that the hardware instruction is a non-functional service request, executing the related non-functional service request and writing a response to the associated memory. The method further includes notifying the guest operating system that the execution of the non-functional service request is complete and the response is available.
