  • Patent number: 10719274
    Abstract: Virtual computing instance data that are stored across multiple storage volumes are replicated in a manner such that the write order is maintained. The frequency of the replication is set so that the recovery point objective defined for the VM data can be satisfied. The replication includes the steps of determining a set of logical storage volumes across which the virtual computing instance issues dependent write IOs, issuing a first command to the virtual computing instance to block new IOs and to block receipt of IO acknowledgements, issuing a command to create replicas of all the logical storage volumes in the set, and then issuing a second command to the virtual computing instance to unblock new IOs and unblock receipt of IO acknowledgements.

  • Publication number: 20200226185
    Abstract: System and methods for automatically publishing Representational State Transfer (REST) Application Programming Interface (API) changes in a cloud environment are described. A publish/subscribe server (PSS) may receive from a subscriber a customized request for monitoring a registered REST API supported by a REST service provider (RSP) and registered with the PSS. The subscriber is configured to invoke the registered REST API at the RSP. The PSS may monitor the registered REST API for any changes at the RSP based on the customized request. In response to a determination that the registered REST API is changed at the RSP, the PSS may generate a REST API change report indicating a change event occurred to the registered REST API at the RSP after being registered with the PSS. The PSS may then transmit the REST API change report to the subscriber. The subscriber is configured to not invoke the registered REST API at the RSP based on the REST API change report.

  • Publication number: 20200228392
    Abstract: The current document is directed to methods and systems that process, classify, efficiently store, and display large volumes of event messages generated in modern computing systems. In a disclosed implementation, received event messages are assigned to event-message clusters based on non-parameter tokens identified within the event messages. A parsing function is generated for each cluster that is used to extract data from incoming event messages and to prepare event records from event messages that more efficiently and accessible store event information. The parsing functions also provide an alternative basis for assignment of event messages to clusters. Event types associated with the clusters are used for gathering information from various information sources with which to automatically annotate event messages displayed to system administrators, maintenance personnel, and other users of event messages.

  • Patent number: 10715577
    Abstract: The disclosure herein describes a server-side system that dynamically enhances user experience on a remoting client device. During operation, the system monitors user inputs on the client device. When a user input involving a predetermined interaction between the user and the GUI on the client device is detected, the system alters parameters of frame encoding based on the user interaction. Frame updates transmitted to the client device during the user interaction are encoded with the altered encoding method to improve user experience. Once the user interaction is ended, the system reverts back to the normal encoding method.

  • Patent number: 10713265
    Abstract: Methods and systems quantize and compress time series data generated by a resource of a distributed computing system. The time series data is partitioned according to a set of quantiles. Quantized time series data is generated from the time series data and the quantiles. The quantized time series data is compressed by deleting sequential duplicate quantized data points from the quantized time series data to obtain compress time series data. Quantization and compression are performed for different combinations of quantiles. The user may choose to minimize information loss of information due to quantization while selecting a lower bound for the compression rate. Alternatively, the user may choose to maximize the compression rate while placing an upper limit on the loss of information due to quantization. The compressed time series data that satisfies the user selected optimization conditions may be used to replace the original time series data in the data-storage device.

  • Patent number: 10705880
    Abstract: Multiple instances of a distributed application are run in a Kubernetes cluster. An updated version of the application must undergo some post-launch initialization before a production workload handled by the original version can be switched to the updated version. Accordingly, a temporary update-monitor pod is inserted into the cluster so that it can query the application as to its update status and report it to a log file. A script external to the cluster can read the log file to determine if initialization is complete. If so, the workload can be switched to the update instance. The temporary update-monitor pod is destroyed to free up resources and to ensure that it is does not pose a security vulnerability.
