Abstract: A computer system for encapsulating a packet between a customer premise for delivery to customer resources within a public cloud data center. The computer system comprises a shim gateway. The shim gateway comprises a plurality of customer specific shim components. The shim gateway is configured to receive a packet from a customer premise. The packet has a VLAN tag. The packet identifies a tenant within a designated virtual network for the customer. The designated virtual network is within the public cloud data center. The shim gateway is further configured to encapsulate the packet into an encapsulated packet. Encapsulation includes mapping the VLAN tag to a destination network address of a tenant gateway for the customer. The tenant gateway is in the designated virtual network. The shim gateway is further configured to forward the encapsulated packet to the tenant gateway in the designated virtual network for delivery to the identified tenant.

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: Computerized methods, systems, and computer-readable media are provided for establishing and managing a virtual network (V-net) and virtual machine (VM) switches that enable protected and isolated interconnections between members of the V-net. The V-net members include an originating network adapter that generates data packets addressed to a destination network adapter. Upon detecting data-packet generation, a source-side VM switch accesses a forwarding table associated with the V-net, ascertains a destination-side, VM-switch locator that corresponds to an identifier of the destination network adapter, and modifies the data packets to include the identifier. The forwarding table represents a mapping between the members of the V-net and VM switches located on respective nodes within the data center. In operation, the mapping enforces communication policies that govern data-packet traffic. Upon receiving the data packets, the destination-side VM switch restores the data packets and forwards them to the destination network adapter.

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 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: 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: 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.
