Abstract

Systems, methods, and computer-readable media for orchestrating cloud to fog interactions. In some examples, a method can involve partitioning an application into software containers, each of the software containers being configured to host a respective component of the application. The method can further involve identifying nodes on respective hierarchical layers of a hierarchical cloud-fog architecture for hosting the software containers on the respective hierarchical layers of the cloud-fog architecture. The hierarchical cloud-fog architecture can include one or more cloud layers and one or more fog layers. The method can also involve deploying the software containers at the nodes on the respective hierarchical layers of the cloud-fog architecture.

deploying the plurality of software containers to the plurality of nodes on the respective hierarchical layers of the cloud-fog architecture.

2. The method of claim 1, wherein each of the plurality of software containers is deployed to one or more respective nodes on a particular hierarchical layer based on a respective service parameter associated with at least one of the application, the plurality of software containers, the plurality of nodes, and the respective hierarchical layers of the hierarchical cloud-fog architecture.

3. The method of claim 2, wherein the respective service parameter comprises at least one of a cost metric, a performance metric, a security metric, a network metric, a resource metric, and a reliability metric.

4. The method of claim 3, wherein the deploying step is triggered by one or more triggering conditions associated with the respective service parameter.

5. The method of claim 1, wherein deploying the plurality of software containers comprises dynamically deploying at least one of the plurality of software containers based on at least one of a triggering event and a current status of a service parameter associated with a current software container.

6. The method of claim 1, wherein the application comprises a service function chain, wherein each service function from the service function chain is associated with a respective one of the plurality of software containers.

7. The method of claim 1, further comprising:

monitoring a respective service parameter of at least one of the plurality of nodes and the respective hierarchical layers, based on data collected by at least one of the plurality of software containers and one or more hosts of the plurality of software containers, the one or more hosts comprising at least one of a network node, a hypervisor, and a compute environment.

8. The method of claim 1, further comprising:

collecting a respective operational context for each of the plurality of software containers; and

moving the respective operational context to one or more respective nodes from the plurality of nodes.

9. The method of claim 8, wherein deploying the plurality of software containers comprises:

moving a software container from the plurality of software containers to a node in a respective layer from the respective hierarchical layers of the hierarchical cloud-fog architecture; and

starting the software container within the node based on the respective operational context associated with the software container.

10. The method of claim 9, wherein the respective operational context associated with the software container is moved to the node prior to at least one of the moving of the software container and the starting of the software container.

11. The method of claim 1, further comprising:

identifying one or more respective potential destination nodes at one or more associated layers from the respective hierarchical layers, for deploying at least one of the plurality of software containers;

generating one or more shadow containers at the one or more respective potential destination nodes, the one or more shadow containers being based on one or more active containers from the plurality of software containers;
