Abstract

Embodiments are disclosed for managing a distributed data center. The managing can include receiving content interaction history associated with a first social networking account of a social networking system at a content distribution system; maintaining a cache map of available cache appliances to implement a distributed cache store; selecting a content item to push to a residential cache appliance based on the content interaction history, wherein pushing the content item includes updating the cache map to associate a network address of the residential cache appliance with an identifier of the content item; and providing a content distribution service configured to redirect a content streaming request for the content item to the residential cache appliance when the content item is determined to be available in the distributed cache store according to the cache map.

Claims

1. A method, comprising:

receiving, at a social networking server system, an indication to share a content item associated with a residential cache appliance and a first social networking account, wherein a privacy setting of the residential cache appliance is at least in part managed by the social networking server system;

associating, at the social networking server system, a network address of the residential cache appliance with the content item;

maintaining, at a storage associated with the social networking server system, a cache map of available residential cache appliances to implement a distributed cache store, wherein for one or more of the available residential cache appliances, the cache map identifies an associated social networking account, an associated network address, associated cache appliance stored content items, and associated privacy settings managed by the social networking server system;

receiving, at the social networking server system and from a requester device associated with a second social networking account, a request for the content item; and

in response to the request, directing, by the social networking server system based at least in part on the cache map, the requester device to the residential cache appliance to obtain at least a portion of the content item.

2. The method of claim 1, wherein associating the network address includes associating the content item with the network address, the network address identifying the residential cache appliance as storing the content item.

3. The method of claim 1, further comprising:

generating a user interface for other social networking accounts to request content associated with the first social networking account, wherein the user interface is configured to provide access to the content item stored in the social networking server system.

4. The method of claim 3, wherein the user interface is configured to provide an option to request the content item from the residential cache appliance.

5. The method of claim 1, wherein the content item is stored in the residential cache appliance in response to determining that the content item is larger than a threshold size for the social networking system to store or to serve to external devices.

6. The method of claim 1, further comprising generating a network efficient representation for the content item.

7. The method of claim 6, wherein the network efficient representation is a derivative content item generated from the content item.

8. The method of claim 6, wherein the network efficient representation is a lower resolution version, a lower sampling rate version, or a lower quality version of the content item.

9. The method of claim 6, wherein the network efficient representation is a symbolic or iconic representation of the content item that is not derived from the content item.

10. The method of claim 1, wherein directing the requester device includes verifying that the second social networking account has a permission to access the content item in the residential cache appliance according to a permission policy associated with the first social networking account.

11. The method of claim 1, wherein directing the requester device includes sending a network address translation message to a domain name service (DNS) server to redirect the request for the content item to the residential cache appliance.

12. The method of claim 1, wherein directing the requester device to the residential cache appliance is in response to determining that a size of the content item exceeds a threshold size for an available network bandwidth of the social networking system to deliver the content item from the social networking system.

13. A system, comprising:

one or more processors configured to;

receive, an indication to share a content item associated with a residential cache appliance and a first social networking account, wherein a privacy setting of the residential cache appliance is at least in part managed by a social networking server system;

associate a network address of the residential cache appliance with the content item;

maintain a cache map of available residential cache appliances to implement a distributed cache store, wherein for one or more of the available residential cache appliances, the cache map identifies an associated social networking account, an associated network address, associated cache appliance stored content items, and associated privacy settings managed by the social networking server system;

receive from a requester device associated with a second social networking account, a request for the content item; and

in response to the request, directing, based at least in part on the cache map, the requester device to the residential cache appliance to obtain at least a portion of the content item; and

memory coupled to the one or more processors.

14. The system of claim 13, wherein associating the network address includes associating the content item with the network address, the network address identifying the residential cache appliance as storing the content item.

15. The system of claim 13, wherein the content item is stored in the residential cache appliance in response to determining that the content item is larger than a threshold size for the social networking system to store or to serve to external devices.

16. The system of claim 13, wherein the one or more processors are further configured to generate a network efficient representation for the content item.

17. The system of claim 16, wherein the network efficient representation is a derivative content item generated from the content item.

18. The system of claim 13, wherein directing the requester device includes verifying that the second social networking account has a permission to access the content item in the residential cache appliance according to a permission policy associated with the first social networking account.

19. The system of claim 13, wherein directing the requester device to the residential cache appliance is in response to determining that a size of the content item exceeds a threshold size for an available network bandwidth of the social networking system to deliver the content item from the social networking system.

20. A computer program product, the computer program product being embodied in a non-transitory computer readable storage medium and comprising computer instructions for:

receiving an indication to share a content item associated with a residential cache appliance and a first social networking account, wherein a privacy setting of the residential cache appliance is at least in part managed by a social networking server system;

associating a network address of the residential cache appliance with the content item;

maintaining a cache map of available residential cache appliances to implement a distributed cache store, wherein for one or more of the available residential cache appliances, the cache map identifies an associated social networking account, an associated network address, associated cache appliance stored content items, and associated privacy settings managed by the social networking server system;

receiving from a requester device associated with a second social networking account, a request for the content item; and

in response to the request, directing based at least in part on the cache map, the requester device to the residential cache appliance to obtain at least a portion of the content item.
