The embodiments set forth techniques for implementing a cloud service that enables cloud data to be shared between different users in a secure manner. One embodiment involves a sharing manager and a sharing client, where the sharing manager is configured to manage various data components stored within a storage system managed by the cloud service. These data components can include user accounts, share objects (for sharing data between users&#x2014;and, in some cases, public users not known to the sharing manager)&#x2014;as well as various 'wrapping objects' that enable data to be logically separated in an organized manner within the storage system. According to this approach, the sharing client is configured to interface with the sharing manager in order to carry out various encryption/decryption techniques that enable the cloud data to be securely shared between the users.

Techniques are disclosed for delivering push subscription notifications in large scale distributed systems. Subscription notifications can be delivered to mobile devices of subscribing users by monitoring, at a server, an application database comprising a data record having one or more data values, detecting, at the server, in accordance with the monitoring, a changed data value, querying a subscription database for a subscription having at least one constant value to be compared to the changed data value in accordance with a trigger condition specified in a trigger template, determining whether the trigger condition is true using the changed data value and the constant value as the values of the first and second variables, respectively, in the at least one comparison; and pushing a notification from the server in response to the trigger condition being true.

Disclosed herein are systems, methods, and non-transitory computer-readable storage media for initiating data synchronization between devices. The method includes sending a host identifier and pairing record to a second device having a file system encrypted on a per file and on a per class basis for a set of classes, receiving from the second device a sync ticket containing encryption keys for the set of classes, and storing the sync ticket. Also disclosed is a method for synchronizing encrypted data between devices. This method includes receiving, at a first device having a file system encrypted on a per file and on a per class basis, a sync ticket containing encryption keys from a second device, retrieving an escrow key bag containing protection class keys, decrypting protection class keys based on the sync ticket, and synchronizing data with the second device based on the decrypted protection class keys.
