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： 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.

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： The present invention extends to methods, systems, and computer program products for offloading virtual machine flows to physical queues. A computer system executes one or more virtual machines, and programs a physical network device with one or more rules that manage network traffic for the virtual machines. The computer system also programs the network device to manage network traffic using the rules. In particular, the network device is programmed to determine availability of one or more physical queues at the network device that are usable for processing network flows for the virtual machines. The network device is also programmed to identify network flows for the virtual machines, including identifying characteristics of each network flow. The network device is also programmed to, based on the characteristics of the network flows and based on the rules, assign one or more of the network flows to at least one of the physical queues.

摘要： A management service that receives requests for the cloud computing environment to host applications, and improves performance of the application using an edge server. In response to the original request, the management service allocates the application to run on an origin data center, evaluates the application by evaluating at least one of the application properties designated by an application code author or provider, or the application performance, and uses an edge server to improve performance of the application in response to evaluating the application. For instance, a portion of application code may be offloaded to run on the edge data center, a portion of application data may be cached at the edge data center, or the edge server may add functionality to the application.

摘要： Candidates that are potentially responsible for user-perceptible network problems may be inferred. In an example embodiment, a system includes an inference engine to produce a list of candidates that are potentially responsible for user-perceptible network problems, with the candidates being network components that may include both services and network elements. A response to a service request may be a non response, an incorrect response, an untimely correct response, or a timely correct response. The user-perceptible network problems may include the untimely correct response as well as the non response and the incorrect response. In another example embodiment, a method includes monitoring a network and producing a list of candidates that are potentially responsible for user-perceptible network problems. The candidates of the list may include both services and network elements of the monitored network.

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.
