摘要： Described is a visual analytics system for network diagnostics. The visual analytics system obtains network diagnostic-related information from a diagnostic system. The visual analytics system includes an interactive user interface that displays the representations of network components, including network machines and, zero or more links between those components, (e.g., as appropriate based upon selection or dynamic conditions). The user interface includes a main network view that displays representations of network components, a diagnostics view that displays suggested diagnosis results obtained from the diagnostic system, and a performance counter view that displays performance counter data. User interaction with one of the views correspondingly changes the displays in the other views. The system allows effective exploration of multiple levels of detail, e.g., variable, component, edge level and network levels, for example, via flexible navigation across these levels from the top, the bottom, or anywhere in the middle, while retaining context.

摘要： Methods, articles, and systems for determining a probable cause of a component's abnormal behavior are described. To determine the probable cause, a computing device computes, for one or more pairs of components having dependency relationships, a likelihood that behavior of one component of a pair is impacting behavior of the other component of the pair. This computing is based on joint historical behavior of the pair of components. The computing device then determines that one of a plurality of components is a probable cause of the abnormal behavior based on the computed likelihoods.

摘要： The use of statistics collected during the parallel distributed execution of the tasks of a job may be used to optimize the performance of the task or similar recurring tasks. An execution plan for a job is initially generated, in which the execution plan includes tasks. Statistics regarding operations performed in the tasks are collected while the tasks are executed via parallel distributed execution. Another execution plan is then generated for another recurring job, in which the additional execution plan has at least one task in common with the execution plan for the job. The additional execution plan is subsequently optimized based at least on the statistics to produce an optimized execution plan.

摘要： A cloud computing environment providing a network service for a client computing entity. The network service is not an application level service, but rather a service that operates at or below the network layer in the protocol stack. For instance, the network service might be a network endpoint service such as a network address service (such as DNS) or a dynamic network service (such as DHCP), or a network traffic service such as a firewall service or a secure tunneling service (such as VPN). The service might also provide a pipeline of network services for network level traffic to and from the client computing entity. The cloud environment uses policy to determine which of a plurality of communication channels to use when exchanging cloud service data for the network service.

摘要： A delivery controller for use in an enterprise environment that communicates with a cloud computing environment that is providing a service for the enterprise. As the cloud service processing progresses, some cloud service data is transferred from the cloud computing environment to the enterprise environment, and vice versa. The cloud service data may be exchanged over any one of a number of different types of communication channels. The delivery controller selects which communication channel to use to transfer specific data, depending on enterprise policy. Such policy might consider any business goals of the enterprise, and may be applied at the application level.

摘要： Constructing an inference graph relates to the creation of a graph that reflects dependencies within a network. In an example embodiment, a method includes determining dependencies among components of a network and constructing an inference graph for the network responsive to the dependencies. The components of the network include services and hardware components, and the inference graph reflects cross-layer components including the services and the hardware components. In another example embodiment, a system includes a service dependency analyzer and an inference graph constructor. The service dependency analyzer is to determine dependencies among components of a network, the components including services and hardware components. The inference graph constructor is to construct an inference graph for the network responsive to the dependencies, the inference graph reflecting cross-layer components including the services and the hardware components.

摘要： A computing cluster operated according to a resource allocation policy based on a predictive model of completion time. The predictive model may be applied in a resource control loop that iteratively updates resources assigned to an executing job. At each iteration, the amount of resources allocated to the job may be updated based on of the predictive model so that the job will be scheduled to complete execution at a target completion time. The target completion time may be derived from a utility function determined for the job. The utility function, in turn, may be derived from a service level agreement with service guarantees and penalties for late completion of a job. Allocating resources in this way may maximize utility for an operator of the computing cluster while minimizing disruption to other jobs that may be concurrently executing.
摘要翻译：一种基于完成时间预测模型的资源分配策略运行的计算集群。预测模型可以应用在资源控制循环中，其循环地更新分配给执行作业的资源。在每次迭代时，可以基于预测模型来更新分配给作业的资源量，使得作业将被调度以在目标完成时间完成执行。目标完成时间可以从为作业确定的效用函数导出。效用函数反过来可能来自服务级别协议，服务保证和作业迟到完成的处罚。以这种方式分配资源可以最大限度地实现计算集群的运营商，同时最大限度地减少可能并发执行的其他作业。

摘要： The provisioning of a host computing system by a controller located over a wide area network. The host computing system has power-on code that automatically executes upon powering up, and causes the host to notify the controller of the host address. In a first level of bootstrapping, the controller instructs the host to download a maintenance operating system. The host responds by downloading and installing a maintenance operating system, enabling further bootstrapping. The persistent memory may further have security data, such as a public key, that allows the host computing system to securely identify the source of the download instructions (and subsequent instructions) as originating from the controller. A second level of bootstrapping may accomplish the configuring of the host with a hypervisor and a host agent. A third level of bootstrapping may accomplish the provisioning of virtual machines on the host.
