Abstract: Technology is disclosed herein for optimizing data caches among multiple interconnected computing devices. According to at least one embodiment, a storage server transfers a first data set to a computing device. The storage server then identifies a neighbor computing device sharing a local area network (LAN) with the computing device. The neighbor computing device maintains a network connection with the storage server. The storage server transmits a second data set relevant to the first data set to the neighbor computing device. In response to a read request for the second data set from the computing device, the storage server sends to the computing device an instruction indicating that the neighbor computing device is storing a data cache for the computing device.

Abstract: Technology disclosed herein includes a method for loading a carrier specific OS onto a computing device depending on what network the computing device is connected to. The computing device detects an identity of a network to which a computing device is connected or is to be connected during a network identification process executed on the computing device. The network can be identified, e.g., by examining a subscriber identification module (SIM) card electronically connected to the computing device. The device then sends a request including the identity of the network to a remote registration service. In turn the device receives an instruction from the remote registration service identifying a distribution of an operating system (OS) specific for the network. After retrieving the OS distribution, the device loads the distribution of the operating system on the computing device.

Abstract: Techniques for a method for automatically synchronizing application state across multiple devices are disclosed herein. The method includes running an instance of a computer application on an electronic device, automatically determining a sync event that occurs in the electronic device, wherein the sync event suggests a synchronization of application state data and the application state data represent an application state of the computer application at the sync event, and transmitting the application state data of the computer application to a storage server in response to the sync event. The application state data of the computer application enables another instance of the computer application to resume the application state at the sync event at another electronic device.

Abstract: Techniques introduced here enable cloud-based file prefetching on electronic devices. The electronic devices store certain files on a remote storage server and preload some of the files locally to include file access efficiency. File access patterns on the electronic devices are analyzed collectively and efficiently using a cloud service to detect global access patterns and help determine which files to preload on each of the electronic devices.

Abstract: Technology is disclosed herein for optimizing network connections using proxy connections. According to at least one embodiment, a computing device receives requests for network connections with remote servers from multiple computer applications running on the computing device. The computing device further establishes a network connection with a proxy server. The proxy server initiates and maintains proxy network connections with the remote servers. The proxy server can delay at least one network message of the network messages received from the remote servers such that the proxy server sends the network messages to the computing device in a batch. The proxy server batches the network messages such that the computing device stays at a high power consumption state for a time period shorter than an overall time period for which the computing device would stay at the high power consumption if the network messages were sent individually without batching.

Abstract: Technology is disclosed for transmitting notification updates to computing devices (“the technology”). Various embodiments of the technology includes a proxy server that facilitates transmission of notifications to the computing devices based on a location proximity and/or access pattern of the computing devices. In one such embodiment, if a particular computing device of the user is not within a predefined location proximity of a primary computing device of the user, the proxy server delays or decreases the frequency of transmission of the notifications to the particular mobile device. In another example, based on the access pattern of the particular computing device, if the proxy server determines that the user is not likely to use the particular computing device, e.g. until a certain point of time, the proxy server delays or decreases the frequency of the transmission of the notifications to the particular mobile device until around that certain point of time.

Abstract: Technology is disclosed herein for resolving synchronization conflicts. According to at least one embodiment, multiple computing devices in a synchronization group can communicate with a cloud storage service for data synchronization. The cloud storage service determines a ranking list for the synchronization group based on a user input indicating the priority of a new computing device in a ranking list. When two conflicting updates to a data set are received from two computing devices, the cloud storage service determines a winning update from the two conflicting updates based on priorities of the first and second computing devices in a ranking list, and distributes the winning update to the computing devices to override the other conflicting update.

Abstract: Technology is disclosed herein for resolving synchronization conflicts when synchronizing application state data between computing devices. According to at least one embodiment, a server detects a first set of application state data at a first computing device conflicting with a second set of application state data at a second computing device. The first and second sets of application state data represent application states of the same computer application running at the first and second computing devices, respectively. Accordingly, the first computing device presents a user interface prompting a user to choose a preferred set of application state data between the first and second sets of application state data. If the user chooses the second set of application state data as the preferred set, the first computing device uses the second set of application state data to overwrite the first set of application state data at the device.

Abstract: Technology is disclosed for regulating data storage based on a popularity of data files (“the technology”). Various embodiments of the technology includes maintaining a fixed durability level of data files stored in a storage system by regulating a number of copies of the data files stored in the storage system. One embodiment includes regulating the number of copies of a particular data file based on popularity of the particular data file among various users using the storage system. The number of copies stored in the storage system is increased or decreased, including from/to zero, based on the popularity of the particular data file. The popularity is determined based on at least one of: a number of computing devices of various users having the particular data file, a latency, network bandwidth and/or availability with the computing devices for reading the particular data file, or access pattern of the particular data file.

Abstract: Technology for a method for backing up and restoring application state across multiple devices is disclosed herein. The method includes running an instance of a computer application at a first electronic device, determining a backup event that occurs in the first electronic device, wherein the backup event suggests a backup of application state data and the application state data represent an application state of the computer application at the backup event, and transmitting the application state data of the computer application to a remote storage service, in response to the backup event. A second electronic device can retrieve the application state data from the remote storage service and restore the application state.
