Abstract: The present disclosure relates to devices and methods for creating one or more proxy devices in a guest device mirroring the devices hosted by a host device. The proxy devices may provide full device access functionality to applications running in the guest device. The devices and methods may load a proxy driver inside the guest device, which communicates with the host device. When applications running on the guest device interact with the proxy devices, the proxy driver communicates the interaction to the host device, which communicates with the device driver managing the device. The devices and methods allow applications running on the host and applications running on the guest to shares access to the same device.

Abstract: Example methods are provided to identify unused memory regions in pages that are allocated for storing executable code. One or more of the unused memory regions are usable as a secure location to store confidential information shared between a hypervisor on the host and a guest (such as a guest virtual computing instance) that runs on the host. The one or more unused memory regions may also be used to store executable code (such as valid executable code of antivirus software or other security program) that has been prevented/delayed in its execution by malicious code that has occupied the pages, thereby providing the executable code with sufficient memory resources to enable the executable code to at least partially complete execution.

Abstract: A method of batch and scheduler migration assesses a batch job, scans it's scheduling mechanism and components, ascertains a quantum change for migrating the batch job to a target batch service and forecasts an assessment statistic that provides at least one functional readiness and a timeline to complete the migration of the batch job. The method generates a transformed batch job structure by breaking the batch job according to the target batch service while retaining the scheduling mechanism. Further, it updates containerized batch service components of the target batch service as per the forecasted assessment statistic and the transformed batch job structure, and migrates the batch job to the target batch service by re-platforming the updated containerized batch service components.

Abstract: Embodiments operate a machine learning (“ML”) notebook in a cloud infrastructure executing a plurality of ML notebooks. Embodiments receive a plurality of previously executed ML notebook feature engineering commands from the plurality of ML notebooks. Embodiments store the plurality of previously executed ML notebook feature engineering commands, including a relationship between the feature engineering commands. Embodiments mine the stored commands to generate feature engineering sets of feature engineering commands, the feature engineering sets comprising feature engineering commands that are frequently used together and an order of use of the feature engineering commands. Embodiments then receive a context of a current feature engineering command and data used in the context and recommend a next feature engineering command to be executed after the current feature engineering command.

Abstract: Live mounting a virtual machine (VM) causes the VM to run off a backup copy or snapshot previously taken of a “live” production VM. The live-mounted VM is generally intended for temporary use such as to validate the integrity and contents of the backup copy for disaster recovery validation, or to access some contents of the backup copy from the live-mounted VM without restoring all backed up files. These uses contemplate that changes occurring during live mount are not preserved after the live-mounted VM expires or is taken down. Thus, live mounting a VM is not a restore operation and usually does not involve access to every block of data in the backup copy. However, live mounting provides live VM service in the cloud sooner than waiting for all of the backup copy/snapshot to be restored.

Abstract: Bitmaps for managing computing resources are described. Example bitmaps described in this application use less memory space by varying the sizes of the nodes in the bitmap's tree structure, and/or by limiting the number of nodes in the bitmap's leaf layer. Other example bitmaps described in this application reduce the time needed to traverse the bitmap by tailoring the search direction according to the bitmap's configuration.

Abstract: System and computer-implemented method for migrating partial tree structures of virtual disks for virtual computing instances between sites in a computer system uses a compressed trie, which is created from target tree structures of virtual disks at a plurality of target sites in the computer system. For a virtual computing instance selected, the compressed trie is used to find candidate target sites based on a disk chain string of the virtual computing instance. For each candidate target site, a cost value for migrating the virtual computing instance along with a partial source tree structure of virtual disks corresponding to the virtual computing instance from the source site to the candidate target site is calculated to select a target site with a lowest cost value as a migration option to reduce storage resource usage in the computer system.

Abstract: Techniques for a cloud-based workload optimization service to identify customer workloads that are optimized to run on burstable instance types. The techniques include identifying workloads that are successfully running on burstable instance types, and using historical-utilization data for those workloads to train classification models. The optimization service can extract feature data from the historical-utilization data, where the feature data represents utilization characteristics that are indicative of burstable workloads. The feature data is then used to train classification models to receive utilization data for candidate workloads, and determine whether the candidate workloads would be optimized for burstable instance types. The optimization service can then migrate suitable workloads to burstable instance types, and/or provide users with recommendations that their workloads are optimized or suitable for burstable instance types.

Abstract: Calls run through a virtual desktop infrastructure server are enhanced by opening a media channel between a personal computing device and a media server for a call initiated using a virtual desktop infrastructure server. A first stream of media data for the call is merged with a second stream of media data for the call in a single virtual channel of the protocol using a first packet queue to store packets of the first stream and a second packet queue to store packets of the second stream as the packets await transmission. A first packet of media data of the first stream is pushed into the first packet queue. A fill level of the first packet queue is compared to a first congest threshold associated with the first packet queue. Responsive to the fill level exceeding the first congest threshold, a congestion mitigation measure is invoked.
