Abstract

Techniques for hot swapping and hot scaling containers between cloud services are disclosed. In one example, a method includes storing, with a cloud exchange, data indicating an association of a first container of a first private network with a second container of a second private network, wherein the first private network and the second private network are coupled to the cloud exchange to send and receive data packets via the cloud exchange. The method further includes sending, with the cloud exchange based on the association, state of the first container to the second container.

Claims

1. A method comprising:

storing, with at least one processor of a cloud exchange, data indicating an association of a first container of a first private network with a second container of a second private network, wherein the first private network and the second private network are coupled to the cloud exchange to send and receive data packets via the cloud exchange; and

sending, with the at least one processor of the cloud exchange, based on the association, state of the first container to the second container.

2. The method of claim 1, further comprising:

receiving, by the cloud exchange, cloud service traffic from an enterprise network; and

redirecting, by the cloud exchange, the cloud service traffic from the first container to the second container.

3. The method of claim 1, wherein the state enables the second container to replicate an operating environment of the first container.

4. The method of claim 1, wherein the state of the first container comprises one or more of:

application data, application stack configuration data, microservice state, memory data, commands, process information, and current instruction pointers.

5. The method of claim 1, wherein copying the state from the first container to the second container is performed while the first container is executing one or more applications.

6. The method of claim 1, further comprising registering a registration handle for the second container with the first container via the cloud exchange.

7. The method of claim 6, wherein the registration handle comprises a network address for a host of the second private network that executes the second container, and a container identifier for the second container.

8. The method of claim 6, wherein copying the state from the first container to the second container comprises the first container using the registration handle to communicate the state to the second container via the cloud exchange.

9. The method of claim 1, wherein associating the address of the first container with the second container comprises registering a Uniform Resource Identifier (URI) of the second container with a data store of container information.

10. The method of claim 1, further comprising creating, with the cloud exchange, the second container, prior to associating the address of the first container with the second container.

11. The method of claim 1, further comprising:

partitioning tasks from the first container between the first container and the second container,

wherein the copying the state from the first container to the second container is performed for the tasks partitioned to the second container.

12. The method of claim 11, wherein partitioning the tasks from the first container between the first container and the second container comprises sending units of workload from the first container to the second container in accordance with one or more policies based on content and one or more rules.

13. The method of claim 1, further comprising:

maintaining, with the cloud exchange, a data store of container registration information, wherein the container registration information comprises data associating the address of the first container with the second container.

14. The method of claim 1, wherein associating the address of the first container with the second container and copying the state from the first container to the second container are performed in response to a customer-entered request.

15. The method of claim 1, wherein associating the address of the first container with the second container and copying the state from the first container to the second container are performed in response to one or more customer-selected hot swap configuration criteria.

16. The method of claim 15, further comprising providing, with the cloud exchange, an interface for receiving the customer-selected hot swap configuration criteria,

wherein the customer-selected hot swap configuration criteria comprise a customer-selected first cloud service provider and a customer-selected second cloud service provider, and

wherein the first container is hosted by the customer-selected first cloud service provider, and the cloud exchange creates the second container with the customer-selected second cloud service provider.

17. The method of claim 15, wherein the one or more customer-selected hot swap configuration criteria are stored in an orchestration engine of the cloud exchange.

18. The method of claim 1, wherein associating the address of the first container with the second container and copying the state from the first container to the second container are performed in response to a timing defined by a customer-selected schedule.

19. The method of claim 1, further comprising:

creating a channel from the first container to the second container; and

orchestrating a migration of the state from the first container to the second container.

20. The method of claim 1, further comprising:

placing a hold on operations of the first container prior to copying the state from the first container to the second container; and
