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: The present invention extends to methods, systems, and computer program products for synchronizing state among load balancer components. Embodiments of the invention include load balancers using a consistent hashing algorithm to decide how new connections should be load balanced. Use of consistent hashing algorithm permits load balancers to work in a stateless manner in steady state. Load balancers start keeping flow state information (destination address for a given flow) about incoming packets when it is needed, i.e., such as, for example, when a change in destination host configuration is detected. State information is shared across load balancers in a deterministic way, which allows knowing which load balancer is authoritative (e.g., is the owner) for a given flow. Each load balancer can reach the authoritative load balancer to learn about a flow that cannot be determined locally.

Abstract: The performance of multicast and/or broadcasting between virtual machines over a virtual network. A source hypervisor accesses a network message originated from a source virtual machine, and uses the network message to determine a virtual network address associated with destination virtual machines (after potentially resolving group virtual network addresses). Using each virtual network address, the hypervisor determines a physical network address of the corresponding hypervisor that supports the destination virtual machine, and also determines a unique identifier for the destination virtual machine. The source hypervisor may then dispatch the network message along with the unique identifier to the destination hypervisor over the physical network using the physical network address of the hypervisor. The destination hypervisor passes the network message to the destination virtual machine identified by the unique identifier.
Abstract translation: 通过虚拟网络在虚拟机之间进行组播和/或广播的性能。 源虚拟机管理程序访问源虚拟机的网络消息，并使用网络消息来确定与目标虚拟机相关联的虚拟网络地址（潜在解决组虚拟网络地址之后）。 使用每个虚拟网络地址，管理程序确定支持目标虚拟机的相应管理程序的物理网络地址，并且还确定目的地虚拟机的唯一标识符。 然后，源虚拟机管理程序可以使用管理程序的物理网络地址将网络消息与唯一标识符一起通过物理网络发送到目的虚拟机管理程序。 目标管理程序将网络消息传递到由唯一标识符标识的目标虚拟机。

Abstract: 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.

Abstract: A system that includes multiple hosts, each running a plurality of virtual machines. The system may be, for example, a cloud computing environment in which there are services and a service coordination system that communicates with the hosts and with the services. The services include a middleware management service that is configured to maintain per-tenant middleware policy for each of multiple tenants. The middleware management service causes the middleware policy to be applied to network traffic by directing network traffic to a middle ware enforcement mechanism. This middleware policy is per-tenant in that it depends on an identity of a tenant.

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: The present application relates to network configurations and specifically to scalable load balancing network configurations. One implementation includes an external client coupled to a scalable load balancing system. The scalable load balancing system includes a load balancing layer that is configured to encapsulate individual incoming packets of a packet flow from the external client. The load balancing layer is further configured to route the incoming packets to target devices on the system. The target devices can span multiple IP subnets. The incoming packets can pass through one or more load balancers of the load balancing layer before reaching individual target devices. Individual target devices can be configured to route at least some outgoing packets of the packet flow to the external client without passing through any of the one or more load balancers.
