Method and system for routing data flows in a cloud storage system
A system, method, and computing device for allowing storage services with a cloud storage system are provided. The method includes dynamically selecting a best route between a cloud storage system (CSS) and a computing device, wherein the CSS is geographically remote from the computing device; and establishing, based on the selected best route, a data flow between the CSS and the computing device, wherein the data flow is established to allow at least a storage service related to the CSS.
1. A computing device for allowing storage services with a designated cloud storage system (CSS), the storage services enabling both storage to the designated CSS and retrieval of data previously stored by the computing device in the designated CSS, comprising:
a processing unit; and
a memory, the memory containing instructions that, when executed by the processing unit, configure the computing device to:
dynamically select a best route between the designated cloud storage system and the computing device, wherein the designated CSS is geographically remote from the computing device; and
establish, based on the selected best route, a data flow between the designated CSS and the computing device, wherein the data flow is established to allow at least a storage service related to the designated CSS;
wherein the best route is one of a direct route between the designated CSS and the computing device and an indirect route through at least one intermediate computing device before the designated CSS;
wherein, from the point of view of the computing device, the storage related service is deemed complete when the data flow is completed with the designated CSS when a direct route is selected and with the intermediate computing device when an indirect route is selected; and
wherein, when an indirect route is selected, the data flow is ultimately completed with the designated CSS.
2. The computing device of claim 1 , wherein the at least a storage service is any one of: file synchronization between the CSS and the computing device, caching of files in the CSS, backup of files to the CSS, and remote access to files in the CSS or in the computing device.
3. The computing device of claim 2 , wherein the computing device is further configured to:
share storage space with other computing devices in a trusted network to provide an increased caching capacity.
4. The computing device of claim 1 , wherein the computing device is any one of: a cloud storage gateway (CSG), and an endpoint.
5. The computing device of claim 1 , wherein the best route is determined based on at least one of: bandwidth, response time, price, data flow type, topological distance, data flow relation type, availability, latency, inclusion in a list of allowable elements, exclusion from a list of allowable elements, and a domain name system (DNS) query resolution.
6. The computing device of claim 1 , wherein the data flow is established based on a data flow template defining at least a relation type of the data flow relation and at least one configurable attribute.
7. The computing device of claim 6 , wherein the at least one configurable attribute includes any of: content to be synchronized or cached, content to be excluded from synchronization or caching, settings, Digital Rights Management (DRM) instructions, and a locking policy.
8. The computing device of claim 7 , wherein the locking policy is an automatic locking policy.
9. The computing device of claim 1 , wherein the at least one intermediate computing device contains local storage that is used by the intermediate computing device to make it appear to the end user device that the storage service was completed by the designated CSS once the storage service is completed with the local storage, whereby the time until the computing device detects completion of the storage related service when an indirect route is selected is decreased with respect to the time until the computing device would detect completion of the storage related service at the designated CSS had a direct route been selected instead.
10. A method for allowing storage services with a designated cloud storage system CSS), the storage services enabling both storage by a computing device to the designated CSS and retrieval of data previously stored by the computing device in the designated CSS, comprising:
dynamically selecting a best route between the designated cloud storage system and the computing device, wherein the designated CSS is geographically remote from the computing device; and
establishing, based on the selected best route, a data flow between the designated CSS and the computing device, wherein the data flow is established to allow at least a storage service related to the designated CSS;
wherein the best route is one of a direct route between the designated CSS and the computing device and an indirect route through at least one intermediate computing device before the designated CSS;
wherein, from the point of view of the computing device, the storage related service is deemed complete when the data flow is completed with the designated CSS when a direct route is selected and with the intermediate computing device when an indirect route is selected; and
wherein, when an indirect route is selected, the data flow is ultimately completed with the designated CSS.
11. The method of claim 10 , wherein the at least a storage service is any one of: file synchronization between the CSS and the computing device, caching of files in the CSS, backup of files to the CSS, and remote access to files in the CSS or in the computing device.
12. The computing device of claim 11 , wherein caching of files in the CSS further comprises:
sharing storage space with other computing devices in a trusted network to provide an increased caching capacity.
13. The method of claim 10 , wherein the computing device is any one of: a cloud storage gateway (CSG), and an endpoint.
14. The method of claim 10 , wherein the best route is determined based on at least one of: bandwidth, response time, price, data flow type, topological distance, data flow relation type, availability, latency, inclusion in a list of allowable elements, exclusion from a list of allowable elements, and a domain name system (DNS) query resolution.
15. The method of claim 10 , wherein the data flow is established based on a data flow template defining at least a relation type of the data flow relation and at least one configurable attribute.
16. The method of claim 15 , wherein the at least one configurable attribute includes any of: content to be synchronized or cached, content to be excluded from synchronization or caching, settings, Digital Rights Management (DRM) instructions, and a locking policy.
17. The method of claim 16 , wherein the locking policy is an automatic locking policy.
18. The method of claim 10 , wherein the at least one intermediate computing device contains local storage that is used by the intermediate computing device to make it appear to the end user device that the storage service was completed by the designated CSS once the storage service is completed with the local storage, whereby the time until the computing device detects completion of the storage related service when an indirect route is selected is decreased with respect to the time until the computing device would detect completion of the storage related service at the designated CSS had a direct route been selected instead.
19. A non-transitory computer readable medium having stored thereon instructions for causing one or more processing units to execute the method according to claim 10 .
