  • Patent number: 10417035
    Abstract: Virtual redundancy for active-standby cloud applications is disclosed herein. A virtual machine (“VM”) placement scheduling system is disclosed herein. The system can compute, for each standby VM of a plurality of available standby VMs, a minimum required placement overlap delta to meet an entitlement assurance rate (“EAR”) threshold. The system can compute a minimum number of available VM slots for activating each standby VM to meet the EAR threshold. For each standby VM of a given application, the system can filter out any server of a plurality of servers that does not meet criteria. If a given server meets the criteria, the system can add the given server to a candidate list; sort, in descending order, the candidate list by the minimum required placement overlap delta and the number of available virtual machine slots; and select, from the candidate list of servers, a candidate server from atop the candidate list.

  • Publication number: 20190044999
    Abstract: Concepts and technologies are disclosed herein for an application deployment engine. A processor that executes an application deployment engine can receive an application request. The processor can obtain network topology data that indicates availability of resources of a data center, an application template associated with the application, and a running time during which an application placement plan is to be identified out of a large number of placement scenarios within the running time. The application template can describe an application flow path associated with the application. The processor can identify the application placement plan, where the application placement plan can include an optimal placement of the application at the data center, before a given running time expires by pruning the large search space. The processor can generate a command to effect deployment of the application in accordance with the application placement plan.

  • Patent number: 9912564
    Abstract: Methods and systems are provided for determining performance characteristics of an application processing system. The method comprises monitoring throughput of a plurality of resources of the system in a selected time window. A change rate is detected in the throughput of the resources, respectively, representative of a change to constancy of workload in at least some of the resources. Such a change in constancy comprises a knee point of a plot of resource usage comprising load relative to throughput. The time of the change rate is identified within the time window. A relatively first to occur of a plurality of resources knee points is determined wherein the resource corresponding to the first to occur is determined to have a fully loaded throughput within the multi-tier processing system. The determination of the first to occur knee point comprises pinpointing a bottleneck starting point within the application processing system.

  • Patent number: 9674093
    Abstract: A method, non-transitory computer readable medium, and apparatus for adapting resources of the cluster of nodes for a real-time streaming workflow are disclosed. For example, the method receives a notification that a node of the cluster of nodes associated with an instance of a process of the real-time streaming workflow is predicted to be a bottleneck, identifies a number of hops to send a resource statement when the bottleneck is predicted that minimizes a ripple effect associated with transmitting the resource statement, transmits the resource statement to at least one or more nodes of the cluster of nodes within the number of hops, receives a response from one of the at least one or more nodes within the cluster of nodes and adapts a resource usage to the at least one of the one or more nodes within the cluster of nodes that the response was received from.

  • Patent number: 9552232
    Abstract: A method provides a recommendation for a cloud configuration for deploying a service. In response to receiving a service request, a database is searched for a cloud configuration. The search is performed by acquiring a resource usage pattern for the service. The resource usage pattern is mapped to a multidimensional space, which is searched for a previously deployed cloud configuration having a similar resource usage pattern. In response to finding a previously deployed cloud configuration, the activity management is determined for the previously deployed cloud configuration. A recommendation is made based on the activity management.

A first set of parameters associated with a workflow received by the first computing device is determined. The first set of parameters is indicative of a need of the first set of computational resources by the first computing device. One or more computational resources from the first set of computational resources are sub-allocated based on the determined first set of parameters.

  • Patent number: 9367294
    Abstract: An embodiment generally relates to systems and methods for improving system performance by reducing fragility of computing systems. A processing module can identify separate ensemble files each comprising interpretations, by separate entities of a workflow, of a phrase in a file. The processing module can compare the interpretations to determine if the interpretations are the same or essentially the same. If the interpretations are neither the same nor essentially the same, a subsequent entity in the workflow can create a new file that replaces an associated interpretation of the phrase with a common interpretation. The subsequent entity can proceed with an intended operation.
