Abstract: Methods and apparatus for interfaces to manage virtual network interface objects. A system may include resource instances and a network interface virtualization coordinator. Responsive to a record creation request, the coordinator creates an interface records that may include an IP address, subnet information and security properties. The coordinator may, in response to a request to attach the record to a resource instance, enable traffic directed to the IP address to flow to the resource instance. In response to a subsequent detach request, the traffic to the IP address may be disabled at the resource instance. The same interface record may be attached to another resource instance in response to another attach request, enabling traffic directed to the IP address to flow to the second resource instance.

Abstract: A request is received to change an association of a network interface record from a first resource instance to a second resource instance. The network interface record may include an IP address associated with the first resource instance. In response to the request, the first resource instance is prevented from receiving data packets addressed to the IP address of the network interface record through a first network interface object attached to the first resource instance. The network interface record is associated with the second resource instance so that the second resource instance is enabled to receive data packets addressed to the IP address of the network interface record through a second network interface object attached to the second resource instance.

Abstract: The claimed system is a multicast programming model for implementation on top of a service oriented framework, specifically a service oriented messaging system. It provides application-layer multicast capability without requiring an IP multicast infrastructure. The claimed system enables service oriented applications to implement multicasting communications easily and efficiently.

Abstract: The claimed system is a service support framework for a multicast programming system implemented on top of a service oriented framework, specifically a service oriented messaging system.

Abstract: Embodiments are provided which include functionality to manage and control a provision of information to end users. In an embodiment, components of a system can be configured to manage and control a delivery of web feed information through an information pipeline. In one embodiment, components of a system can be configured to manage and control a delivery of subscription content and other information associated with a number of subscriptions to user email applications. A framework can be configured to use one or more serving components when managing and controlling the delivery of subscription content to end users. Other embodiments and functionality are available.

Abstract: The claimed method and system is an API set to support a multicast programming model for implementation on top of a service oriented framework, specifically a service oriented messaging system.
