The DNS server selects a network computing component for processing the requested resource based on the DNS portion of the resource identifier and transmits information identifying the selected network computing component to the client computing device.

Abstract: Systems and methods are described for accurately determining which of a set of networked computing environments most closely approximates a target computing environment. The determination is based on executing a reference workload in the target computing environment and calculating a coefficient of equivalency for each of the networked computing environments, which relates the performance of one or more computing resources in the target computing environment to the corresponding resources in the networked computing environments. The coefficient of equivalency may further be used to determine which of a set of networked computing environments will provide a target level of performance when executing the workload. The target computing environment may be assessed in terms of time, cost, percentage of capacity utilized, or other criteria.

Illustratively, the computing resources may include program execution capabilities, data storage or management capabilities, network bandwidth, etc. The systems or methods automatically allocate computing resources for execution of one or more programs associated with the user. The systems and methods may enable the user to make changes to the allocated resources after execution of the one or more programs has started.

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: Systems and methods are presented for enabling a user to provide rules for the placement of computing resources at a data center for an entity that employs or is associated with the user. The data center can use the placement rules to select a data center computer system to host computing resources for a user. The rules can be used to establish diversity in computing resource placement at the data center thereby reducing the number of users who lose access to computing resources when a specific data center computer suffers a failure. Further, the placement rules can be used to facilitate configuration of the computer resources for the user based, for example, on the user's employment responsibilities.
