Abstract: Mobile device applications may be developed and distributed which include abbreviated, content-based references for one or more network resources. Network resource references may be identified by a native shell running on a mobile device, and a network resource lookup may be performed in order to resolve the network resource reference to the network resource. This allows for dynamic access to network-accessible resources such as catalog services, metric services, and advertising services. A mobile application may provide in-app access to such resources without requiring the application's developer to include detailed application programming interface functionality specific to a particular network resource.

Abstract: Systems and methods are disclosed which detect unresponsive interactions with display pages. Specifically, a client computing device may retrieve display pages from a remote computing system for local display. A local interaction monitoring component may monitor local interactions with the display pages, identify those interactions that did not produce a change in the display page as unresponsive interactions, and transmit unresponsive interaction information to the remote computing system. The remote system may aggregate the unresponsive interaction information to determine unresponsive elements of the display page and modify page templates associated with the unresponsive elements to reduce unresponsive interactions.

Abstract: A system and method for content distribution are provided. A content provider generates a network topology having one or more subnetworks made up of content sources. The content provider segments content, such as applications, into segments for distribution. The content provider then distributes the content such that for each identified subnetwork, each content segment is distributed to a content source. Subsequent, client computing device requests for content can be serviced by selecting a content source in a particular subnetwork selected for delivering the requested content to the client computing device to minimize traffic flow of the requested content through the nodes of the distribution network.

Abstract: In accordance with a designation of a private alias endpoint as a routing target for traffic directed to a service from within an isolated virtual network of a provider network, a tunneling intermediary receives a baseline packet generated at a compute instance. The baseline packet indicates a public IP (Internet Protocol) address of the service as the destination, and a private IP address of the compute instance as the source. In accordance with a tunneling protocol, the tunneling intermediary generates an encapsulation packet comprising at least a portion of the baseline packet and a header indicating the isolated virtual network. The encapsulation packet is transmitted to a node of the service.
