Abstract

Non-disruptively moving a storage fleet control plane, including deploying, on an edge device, one or more agents that are managed by a control plane residing in a cloud computing environment; mediating one or more API requests, generated by the control plane, directed to the one or more agents on the edge device; and migrating, in response to a first condition, the control plane to the edge device.

Claims (42)

1. A method comprising:

deploying, on an edge device, one or more agents that process control messages generated from one or more API requests sent by a control plane residing remotely in a cloud computing environment, wherein the one or more API requests are converted into control messages formatted for the one or more agents on the edge device; and

migrating, in response to a first condition, the control plane to the edge device, whereupon the one or more API requests are dispatched directly from the control plane residing on the edge device, bypassing conversion.

2. The method of claim 1 , wherein the control plane includes one or more containerized microservices.

3. The method of claim 1 , wherein the edge device is embodied in a storage system; wherein the one or more agents are storage service agents; and wherein the control plane provides one or more storage and data services utilizing the one or more storage service agents.

4. The method of claim 1 , wherein the one or more agents are configured to interface with one or more local APIs of the edge device.

5. The method of claim 1 , wherein the control plane and the one or more agents utilize a particular API architecture; and wherein the control plane utilizes the particular API architecture when residing in the cloud computing environment and when residing on the edge device subsequent to migration.

6. The method of claim 1 , wherein the first condition relates to at least one of an availability of the control plane, a quality of a data link between the control plane and the one or more agents, and a user request.

7. The method of claim 1 , wherein the conversion of the one or more API requests into control messages formatted for the one or more agents on the edge device includes:

receiving, by an edge management service associated with the control plane, an API request directed to one of the agents;

converting, by the edge management service, the API request to a control message that is formatted for a control channel between the cloud computing environment and the edge device; and

providing, by the edge management service to the edge device, the control message.

8. The method of claim 7 , wherein the control message is embodied in an Internet-of-Things (IoT) message and the control channel includes an IoT messaging layer.

9. The method of claim 8 , wherein the IoT message encapsulates the API request.

10. The method of claim 1 , wherein the conversion of the one or more API requests into control messages formatted for the one or more agents on the edge device includes:

receiving, by an edge management gateway of the edge device, a control message that encapsulates an API request generated by the control plane;

translating, by the edge management gateway of the edge device, the control message to the API request; and

routing, by the edge management gateway of the edge device, the API request to an agent on the edge device.

11. The method of claim 1 , wherein, subsequent to migration of the control plane, an API request generated by the migrated control plane and received by an agent bypasses conversion by an edge management node in the cloud computing environment.

12. The method of claim 1 further comprising:

migrating, in response to a second condition, the control plane from the edge device to the cloud computing environment.

13. An apparatus comprising:

a memory; and

a processor, operatively coupled to the memory, configured to:

deploy, on an edge device, one or more agents that process control messages generated from one or more API requests sent by a control plane residing remotely in a cloud computing environment, wherein the one or more API requests are converted into control messages formatted for the one or more agents on the edge device; and

migrate, in response to a first condition, the control plane to the edge device, whereupon the one or more API requests are dispatched directly from the control plane residing on the edge device, bypassing conversion.

14. The apparatus of claim 13 , wherein the edge device is embodied in a storage system; and wherein the control plane includes one or more storage and data services for the storage system.

15. The apparatus of claim 13 , wherein the one or more agents are configured to interface with one or more local APIs of the edge device.

16. The apparatus of claim 13 , wherein the conversion of the one or more API requests into control messages formatted for the one or more agents on the edge device includes:

receive, by an edge management service associated with the control plane, an API request directed to one of the agents;

convert, by the edge management service, the API request to a control message that is formatted for a control channel between the cloud computing environment and the edge device; and

provide, by the edge management service to the edge device, the control message.

17. The apparatus of claim 13 , wherein the conversion of the one or more API requests into control messages formatted for the one or more agents on the edge device includes:

receive, by an edge management gateway of the edge device, a control message that encapsulates an API request generated by the control plane;

translate, by the edge management gateway of the edge device, the control message to the API request; and

route, by the edge management gateway of the edge device, the API request to an agent on the edge device.

18. The apparatus of claim 13 , wherein, subsequent to migration of the control plane, an API request generated by the migrated control plane and received by an agent bypasses conversion by an edge management node in the cloud computing environment.

19. The apparatus of claim 13 , the processor further configured to:

migrate, in response to a second condition, the control plane from the edge device to the cloud computing environment.

20. A non-transitory computer readable storage medium storing instructions, which when executed, cause a processor to:

deploy, on an edge device, one or more agents that process control messages generated from one or more API requests sent by a control plane residing remotely in a cloud computing environment, wherein the one or more API requests are converted into control messages formatted for the one or more agents on the edge device; and

migrate, in response to a first condition, the control plane to the edge device, whereupon the one or more API requests are dispatched directly from the control plane residing on the edge device, bypassing conversion.
