Abstract

A cloud-based file system receives a subscription request associated with a networked device and identifying a set of one or more resources of the cloud-based file system and a set of one or more resource modifications. The cloud-based file system determines whether the networked device is authorized to access the resource, and, if so, records a subscription based on the subscription request. In response to a user, an application, or other suitable entity making a modification in the set of modifications to a resource in the set of resources, the cloud-based file system generates a notification to the networked device and to other networked devices with subscriptions that include the modification to the resource. The notification may identify the subscription with which the notification is associated, provide information identifying the modification, or provide other suitable information.

First claim

What is claimed is:

1. A computer-implemented method of notifying a networked device of a modification to a data file of a cloud-based file system, comprising:
receiving, from the networked device, a subscription request to obtain information pertaining to the modification of the data file by a user device of a user that has permission to modify the data file that is stored on the cloud-based file system, wherein the subscription request identifies the networked device and one or more modification actions to the data file by the user device that prompt a notification of the modification to the data file to be generated for the network device, wherein the one or more modification actions to the data file comprise at least one of generating the data file, accessing the data file, deleting the data file, or changing content of the data file;
receiving, from the user device of the user, an authorization of the networked device to subscribe to receive the notification of the modification to the data file, wherein the authorization identifies the networked device, which is different from the user device;
recording the authorization;
determining whether the networked device identified in the subscription request is identified in the recorded authorization;
responsive to determining that the networked device identified in the subscription request is identified in the recorded authorization, recording a subscription based on the subscription request, wherein the subscription identifies the networked device as having subscribed to receive the notification of the modification to the data file responsive to satisfaction of the one or more modification actions to the data file by the user device;
identifying an action performed to the data file by the user device of the user;
responsive to determining that the action performed by the user device of the user corresponds to at least one of the one or more modification actions to the data file identified in the subscription, transmitting to the networked device the notification of the modification to the data file; and
responsive to a satisfaction of one or more predetermined criteria, deleting the recorded subscription, wherein the one or more predetermined criteria comprise a failure to receive a message from the networked device within a predetermined amount of time subsequent to the transmission of the notification to the networked device.

2. The method of claim 1 , wherein the one or more predetermined criteria comprise reception of a subscription cancelation request from the networked device.

3. The method of claim 1 , wherein the one or more predetermined criteria comprise passage of a predetermined amount of time.

4. The method of claim 1 , wherein the notification identifies the subscription with which the notification is associated.

5. The method of claim 1 , wherein the notification identifies the one or more modification action actions performed to the data file by the user device.

6. The method of claim 1 , further comprising transmitting, in response to recording the subscription, a subscription acknowledgment to the networked device.

7. The method of claim 6 , wherein the subscription acknowledgment comprises information regarding a status of the data file.

8. A cloud storage system, comprising:
a memory; and
a processor, coupled to the memory, to:
receive, from a networked device, a subscription request to obtain information pertaining to a modification of a data file by a user device of a user that has permission to modify the data file that is stored on the cloud storage system, wherein the subscription request identifies the networked device and one or more modification actions to the data file by the user device that prompt a notification of the modification to the data file to be generated for the network device, wherein the one or more modification actions to the data file comprise at least one of generating the data file, accessing the data file, deleting the data file, or changing content of the data file;
receive, from the user device of the user, an authorization of the networked device to subscribe to receive the notification of the modification to the data file, wherein the authorization identifies the networked device, which is different from the user device;
record the authorization;
determine whether the networked device identified in the subscription request is identified in the recorded authorization;
responsive to determining that the networked device identified in the subscription request is identified in the recorded authorization, record a subscription based on the subscription request, wherein the subscription identifies the networked device as having subscribed to receive the notification of the modifications to the data file responsive to satisfaction of the one or more modification actions to the data file by the user device;
identify an action performed to the data file by the user device of the user;
responsive to determining that the action performed by the user device of the user corresponds to at least one of the one or more modification actions to the data file identified in the subscription, transmit to the networked device the notification of the modification to the data file; and
responsive to a satisfaction of one or more predetermined criteria, delete the recorded subscription, wherein the one or more predetermined criteria comprise a failure to receive a message from the networked device within a predetermined amount of time subsequent to the transmission of the notification to the networked device.

9. The cloud storage system of claim 8 , wherein the one or more predetermined criteria comprise reception of a subscription cancelation request from the networked device associated with the subscription.

10. The cloud storage system of claim 8 , wherein the one or more predetermined criteria comprise passage of a predetermined amount of time.

11. The cloud storage system of claim 8 , wherein the notification identifies the subscription.

12. The cloud storage system of claim 8 , wherein the notification identifies the one or more modification action actions performed to the data file by the user device.

13. The cloud storage system of claim 8 , wherein the processor is further to transmit, in response to recording the subscription, a subscription acknowledgment to the networked device.

14. The cloud storage system of claim 13 , wherein the subscription acknowledgment comprises information regarding a status of the data file.

15. A non-transitory computer-readable medium comprising instructions, which when executed by a processor, cause the processor to perform operations comprising:
receiving, from a networked device, a subscription request to obtain information pertaining to a modification of a data file by a user device of a user that has permission to modify the data file that is stored at a cloud-based file system, wherein the subscription request identifies the networked device and one or more modification actions to the data file by the user device that prompt a notification of the modification to the data file to be generated for the network device, wherein the one or more modification actions to the data file comprise at least one of generating the data file, accessing the data file, deleting the data file, or changing content of the data file;
receiving, from the user device the user, an authorization of the networked device to subscribe to receive the notification of the modification to the data file, wherein the authorization identifies the networked device, which is different from the user device;
recording the a
