Abstract: Technology is disclosed herein for executing multiple gaming applications on a computing device. According to at least one embodiment, a computing device receives requests for network connections with remote servers from multiple gaming 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 batches network messages received from the remote servers, where the network messages includes gaming content. The proxy server aggregates network messages received in a time period into a single batch, where a time length of the time period is determined based on one or more game events of the games being played on the computing device. Further, the proxy server batches network messages such that the computing device stays at a high power consumption state for a shorter time period than an overall time period required without batching.

Abstract: Technology is disclosed for decomposing an application into fragments and streaming the application fragments for execution on a mobile computing device. A fragment presents a user interface of the application and needs a set of resources, e.g., images, icons, etc. to be executed. A server determines a set of fragments for the application and streams them to the device as and when the device needs a particular fragment. The server determines the set of fragments in various ways. For example, the server executes an emulator that simulates the execution of the application by the user and determines fragment data including the set of fragments, resources needed by each of the fragments, and various possible navigations between the fragments. In another example, the server receives such fragment data from various users executing the application on various devices, and aggregates them based on aggregating policy to obtain an aggregated fragment data.

Abstract: Technology is disclosed for migrating at least portions of a video streaming application to a cloud server. The migration is based on an optimization factor of a video streaming application. The optimization factor can be computed based on consumption of computing resources of the computing device. The video streaming application is a multi-threaded application in which a background thread performs tasks that may not require user interaction and a foreground thread performs tasks that may require user interaction. A service component of the video streaming application that obtains video streaming data from video servers is one example of the background thread. A user interface component that displays the video streaming data to a user via a user interface is an example of the foreground thread. If the optimization factor of the service component is below a predefined threshold, the service component is transferred to the cloud server for further processing.
