Abstract

A network ontology can be determined for at least one node indicated for migration. The network ontology can describe nodes with which the indicated node has a communication relationship. These nodes and the indicated node can be added to a migration group, and each node of the migration group can be migrated to a cloud infrastructure.

Claims

1. A computer-implemented method for migrating nodes of a network to a cloud infrastructure, the method comprising:

receiving an indication of at least one node to migrate;

determining a network ontology for the at least one indicated node, the network ontology describing one or more nodes for which the indicated node has a communicates_with relationship;

adding the indicated node and at least one node of the network ontology for the indicated node to a migration group; and

migrating each node of the migration group to a cloud infrastructure.

2. The method of claim 1 further comprising preparing a migration-configuration file for each node of the migration group.

3. The method of claim 2 wherein the migration-configuration file specifies a service tier for the respective node.

4. The method of claim 2 wherein the migration-configuration file specifies a network configuration to other nodes of the migration group.

5. The method of claim 2 wherein the migration-configuration file specifies a network configuration to non-migrated members of the network ontology of the indicated node.

6. The method of claim 2 further comprising providing the migration-configuration file to a cloud migration module of an agent at the node.

7. The method of claim 2 further comprising providing a migration agent to each node of the migration group.

8. The method of claim 1 further comprising determining the migratable components of the ontology of the indicated node.

9. A computer-implemented method comprising:

processing a network ontology to identify one or more candidates as candidates for migration to a cloud computing infrastructure; and

displaying the candidates for migration to a user.

10. The method of claim 9 further comprising:

applying one or more criteria to the candidates for migration;

ranking the candidates for migration according to the criteria; and

displaying the ranking of the candidates for migration to the user.

11. The method of claim 10 wherein the criteria comprises at least one performance parameter.

12. The method of claim 9 wherein the candidates for migration comprise virtual machines of the enterprise network, the method comprising ranking the virtual machines according to at least one performance parameter.

13. The method of claim 9 wherein determining candidates for migration comprises processing the network ontology to determine one or more service groups that comprise only virtual machines.

14. The method of claim 9 wherein determining candidates for migration comprises processing the network ontology to determine one or more service groups that comprise only virtual machines and physical machines that can be converted to virtual machines.

15. The method of claim 9 wherein determining candidates for migration comprises processing the network ontology to determine one or more service groups that comprise an unreliable network device.

16. The method of claim 9 wherein determining candidates for migration comprises processing the network ontology to determine one or more service groups that comprise devices that have not achieved a configuration drift for a predetermined period.

17. The method of claim 9 further comprising:

determining a plurality of service groups of the enterprise network, each service group comprising a plurality of nodes that have a communication relationship;

determining a state of the plurality of service groups;

ranking the service groups by state; and

displaying the ranking of the service groups to a user.

18. The method of claim 17 comprising determining the migratable components of the service group.

19. A system for migration of one or more nodes of an enterprise to a cloud infrastructure, the system comprising:

an administration console to;

determine a network ontology for at least one node of the enterprise network, the network ontology describing one or more nodes for which the indicated node has a communicates_with relationship;

generate a migration group comprising a plurality of nodes of the network ontology; and

generate a migration configuration file for each node of the migration group.

20. The system of claim 19 wherein the network ontology is determined from one or more source-to-destination communication relationships during execution of one or more executables on the at least one node.

21. A non-transitory computer readable medium including instructions that, when executed by a computing device, cause the computing device to perform a method comprising:

receiving an indication of at least one node to migrate;

determining a network ontology for the at least one indicated node, the network ontology describing one or more nodes for which the indicated node has a communicates_with relationship;

adding the indicated node and at least one node of the network ontology for the indicated node to a migration group; and

migrating each node of the migration group to a cloud infrastructure.
