Abstract: The ensuring of predictable and quantifiable networking performance includes adaptively throttling the rate of VM-to-VM traffic flow. A receiving hypervisor can detect congestion and communicate messages for throttling traffic flow to reduce congestion at the receiving hypervisor.

Abstract: The ensuring of predictable and quantifiable networking performance. Embodiments of the invention combine a congestion free network core with a hypervisor based (i.e., edge-based) throttling design to help insure quantitative and invariable subscription bandwidth rates. A lightweight shim layer in a hypervisor can adaptively throttle the rate of VM-to-VM traffic flow. A receiving hypervisor can detect congestion and communicate back to sending hypervisors that rates are to be regulated. In response, sending hypervisors can reduce transmission rate to mitigate congestion at the receiving hypervisor. In some embodiments, the principles are extended to any message processors communicating over a congestion free network.

Abstract: 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.

Abstract: Methods, systems, and computer-readable media for automating deployment of service applications by exposing environmental constraints in a service model are provided. In general, the methods are performed in the context of a general purpose platform configured as a server cloud to run various service applications distributed thereon. Accordingly, the general purpose platform may be flexibly configured to manage varying degrees of characteristics associated with each of the various service applications. Typically, these characteristics are provided in the service model that governs the environmental constraints under which each component program of the service application operates. As such, hosting environments are selected and adapted to satisfy the environmental constraints associated with each component program.

Abstract: A regional data center system corresponding to a particular region of the world. The data center system includes multiple data centers, each configured such that region-specific requests for services may be satisfied by any of the data centers. One or more of the data centers may also perform load balancing on received region-specific request. In order to perform load balancing, the receiving data center may itself process the requests, but in some cases may determine that the request is to be processed by another data center within the regional data center system.

Abstract: Software deployment to server nodes within large-scale networked systems is provided using image-based deployment. A mostly immutable image is provided at a central service and transferred from the central service to the server nodes. The image includes a base image, which is immutable, and a delta image, which is writable and provides role-specific and/or node-specific state to the base portion. When a server node receives an image from the central server, the server node stores the image intact without installation. The server node then runs software directly from the stored image.

Abstract: The resources needed by an application to execute are declared by the application. When the application is activated, only the declared resources are made available to the application because only the declared resources are connected to the execution environment. Accessibility to resources may be controlled by the operating system by making the resource visible or invisible to the executing software by mapping a local name used by the executing software to a global resource, possibly limiting the type of access allowed. Because the executing software relies on the mapping function performed by the operating system for access to resources, and the operating system only maps names declared by the software, the operating system can isolate the software, and prevent the application from accessing undeclared global resources.

Abstract: Systems, methods and computer storage media for operating a scalable computing platform are provided. A service description describing a requested service is received. Upon receiving the service description a determination of the required resources and the available resources is made. An instance description is produced. The resources required to sustain the deployment of the service are mapped to the available resources of the computing platform so the service may be deployed. The instance description is amended with each deployment of the service to allow for sustained deployment of the service.

Abstract: 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.

Abstract: 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.

Abstract: A containment mechanism provides for the grouping and isolation of multiple processes running on a single computer using a single instance of the operating system. A system is divided into one or more side-by-side and/or nested isolated environments enabling the partitioning and controlled sharing of resources by creating different views of hierarchical name spaces via virtual hierarchies.
