Abstract

A method, system and computer program product for performing cache sharing of enterprise data among peer mobile devices. An enterprise server receives a request from a mobile device for enterprise data. Upon identifying peer mobile device(s) that store the requested enterprise data, the enterprise server selects one of these peer mobile devices to provide the requested enterprise data based on an algorithm. A message is sent to the selected peer mobile device from the enterprise server to provide the requested enterprise data to the requesting mobile device, where the message includes connection details as well as a key that uniquely identifies the requested enterprise data that is stored in a cache of the peer mobile device. In this manner, the enterprise data may be shared in a robust and transparent manner while at the same time providing the enterprise control over the dissemination of the enterprise data.
