Abstract

Disclosed are systems, methods and computer-readable storage medium for extending a private cloud to a public cloud. The private cloud can be extended to the public cloud by establishing a virtual private network between a private cloud and a public cloud, receiving one or more access control lists provisioned by the private cloud, determining contracts between an end point group of the private cloud and an end point group of the public cloud based on the one or more access control lists, and extending the end point group of the private cloud to the end point group of the public cloud across the virtual private network.

First claim

The invention claimed is:

1. A method of extending a private cloud to a public cloud, the method comprising:
establishing, by an orchestrator, a virtual private network between a private cloud and a public cloud, wherein the private cloud is behind a firewall;
receiving, by the orchestrator, one or more access control lists provisioned by the private cloud;
determining, by the orchestrator, contracts between an end point group of the private cloud and an end point group of the public cloud based on the one or more access control lists;
extending, by the orchestrator, the end point group of the private cloud to the end point group of the public cloud across the virtual private network; and
monitoring and troubleshooting, by the orchestrator, the end point group of the public clouds and associated public endpoints of the public cloud.

2. The method of claim 1 , wherein the extending further comprising:
enabling bi-directional communication between the end point group of the private cloud and the end point group of the public cloud.

3. The method of claim 1 , further comprising:
creating, by the orchestrator at the private cloud, a layer three connection bridge between the private cloud and the public cloud, wherein the layer three connection bridge is configured to enable communication from the end point group in the private cloud to the end point group in the public cloud.

4. The method of claim 3 , wherein the layer three connection bridge communicates with the end point group of the private network using a set of security and connectivity rules based on the contracts.

5. The method of claim 1 , wherein the end point groups of the private cloud and the public cloud are in a web network tier.

6. The method of claim 1 , wherein the orchestrator is at the private cloud.

7. The method of claim 1 , wherein the orchestrator is at the public cloud.

8. An orchestrator of a private cloud comprising:
a processor device; and
a computer-readable storage medium device having stored therein instructions which, when executed by the processor device, cause the processor device to:
establish a virtual private network between a private cloud and a public cloud, wherein the private cloud is behind a firewall;
receive one or more access control lists provisioned by the private cloud;
determine contracts between an end point group of the private cloud and an end point group of the public cloud based on the one or more access control lists;
extend the end point group of the private cloud to the end point group of the public cloud across the virtual private network; and
monitoring and troubleshooting the end point group of the public cloud and associated public endpoints of the public cloud.

9. The orchestrator of claim 8 , comprising further instructions which, when executed by the processor device, cause the processor to:
enable bi-directional communication between the end point group of the private cloud and the end point group of the public cloud.

10. The orchestrator of claim 8 , comprising further instructions which, when executed by the processor device, cause the processor device to:
create, at the private cloud, a layer three connection bridge between the private cloud and the public cloud, wherein the layer three connection bridge is configured to enable communication from the end point group in the private cloud to the end point group in the public cloud.

11. The orchestrator of claim 10 , wherein the layer three connection bridge communicates with the end point group of the virtual private network using a set of security and connectivity rules based on the contracts.

12. The orchestrator of claim 8 , wherein the end point groups of the private cloud and the public cloud are in a web network tier.

13. The orchestrator of claim 8 , wherein the orchestrator is at the private cloud.

14. The orchestrator of claim 8 , wherein the orchestrator is at the public cloud.

15. A non-transitory computer-readable storage medium having stored therein instructions which, when executed by a processor of an orchestrator, cause the processor to perform operations comprising:
establish a virtual private network between a private cloud and a public cloud, wherein the private cloud is behind a firewall;
receive one or more access control lists provisioned by the private cloud;
determine contracts between an end point group of the private cloud and an end point group of the public cloud based on the one or more access control lists;
extend the end point group of the private cloud to the end point group of the public cloud across the virtual private network; and
monitor and troubleshoot, by the orchestrator, the end point group of the public cloud and associated public endpoints of the public cloud.

16. The non-transitory computer-readable storage medium of claim 15 , the operations further comprising:
enable bi-directional communication between the end point group of the private cloud and the end point group of the public cloud.

17. The non-transitory computer-readable storage medium of claim 15 , the operation further comprising:
create, at the private cloud, a layer three connection bridge between the private cloud and the public cloud, wherein the layer three connection bridge is configured to enable communication from the end point group in the private cloud to the end point group in the public cloud.

18. The non-transitory computer-readable storage medium of claim 17 , wherein the layer three connection bridge communicates with the end point group of the virtual private network using a set of security and connectivity rules based on the contracts.

19. The non-transitory computer-readable storage medium of claim 15 , wherein the end point groups of the private cloud and the public cloud are in a web network tier.

20. The non-transitory computer-readable storage medium of claim 15 , wherein the orchestrator is at the private cloud.
