A device may receive application information of an application to be deployed in a cloud computing environment. The application information may include requirement information including information defining a compute requirement of the application, a storage requirement of the application, and a network connectivity requirement of the application, and first capability information identifying requested capabilities of the first set of devices. The device may receive second capability information identifying actual capabilities of the second set of devices. The device may compare the first capability information and the second capability information to determine a measure of similarity between the first capability information and the second capability information. The device may generate deployment information for deploying the application on a device, of the second set of devices, based on the measure of similarity.

A message-limiting mechanism for enabling computing devices to self-organize into groups based on network proximity can entail the transmission of values based on hierarchical evaluation such that only a computing device having a most extreme value continues to transmit. The values utilized can be randomly generated and their broadcast can facilitate the identification of computing devices that are proximate, by network distance. Each computing device can retain a most extreme value received, unless a value generated by that computing device itself is more extreme, in which case the computing device can continue periodic broadcasts of its value. Each computing device can report its retained values, or its own value if no values were retained, and groupings can be generated based on the values reported by the computing devices. The grouping of computing devices can then facilitate the identification of peers, including for purposes of downloading content from such peers.

The present disclosure discloses a system and method for obtaining data through selecting a mirror server according to identification data. By a technical means that after a master server selects a corresponding mirror server for a consumption host, when the master server detects that target data changes, the master server transmits an event notification message to the mirror server, and the mirror server transmits a download notification message to the consumption host, so that the consumption host downloads the target data from the mirror server, the load and complexity of a network management department to maintain access permissions of cross-domain access to servers can be reduced, and the technical effect of increasing the speed of downloading the target data by the consumption host is achieved.

Personal electronic devices are organized into a personal electronic device network. One of the personal electronic devices is designated as a device management hub. Based on contextual information from the personal electronic device network, a current activity of a user is predicted, and based on the predicted current user activity and the contextual information, one or more hierarchy is cognitively derived. The device management hub uses one of the hierarchy to contextually assign user input to one of the personal electronic devices for processing. Cognitively predicting the current user activity can include analyzing, by the device management hub, contextual information from the personal electronic devices.
