Abstract

A method for migrating network entities to a cloud computing infrastructure includes receiving an indication of at least one node of a plurality of nodes to migrate from an enterprise network to a cloud computing infrastructure, identifying one or more related nodes of the plurality of nodes that have direct and indirect communication relationships with the indicated node, and adding the indicated node and at least one node of the related nodes for the indicated node to a migration group. The method includes preparing a migration-configuration file for each node of the migration group, the migration-configuration file comprising service level agreement (SLA) information, deploying a migration agent to each node of the migration group, and migrating the migration group to the cloud computing infrastructure, wherein each node of the migration group is migrated using a corresponding migration-configuration file to generate an SLA for each node of the migration group with a provider of the cloud computing infrastructure in view of SLA information from the corresponding migration configuration file.

First claim

What is claimed is:

1. A method comprising:
receiving an indication of at least one node of a plurality of nodes to migrate from an enterprise network to a cloud computing infrastructure, the indicated node comprising a first virtual machine;
identifying, by a processing device, one or more related nodes of the plurality of nodes that have direct and indirect communication relationships with the indicated node, the related nodes comprising a second virtual machine;
adding the indicated node and at least one node of the related nodes for the indicated node to a migration group;
preparing a migration-configuration file for each node of the migration group, the migration-configuration file comprising service level agreement (SLA) information;
deploying a migration agent to each node of the migration group; and
migrating the migration group to the cloud computing infrastructure, wherein each node of the migration group is migrated using a corresponding migration-configuration file to generate an SLA for each node of the migration group with a provider of the cloud computing infrastructure in view of SLA information from the corresponding migration configuration file.

2. The method of claim 1 wherein the one or more related nodes are identified in view of a network ontology for the indicated node, the network ontology being created for the indicated node using a data collection agent deployed to the indicated node, the network ontology describing current state of the indicated node and the related nodes.

3. The method of claim 1 wherein the SLA information in the migration-configuration file specifies a service tier for the respective node.

4. The method of claim 1 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 1 further comprising providing the migration-configuration file to a cloud migration module of the migration agent at the node.

7. The method of claim 2 further comprising determining migratable components of the ontology of the indicated node.

8. The method of claim 2 further comprising distributing instances of the data collection agent to the plurality of nodes, wherein an instance of the data collection agent is to monitor data packet traffic between an adaptive layer and a protocol layer of a corresponding node, and to report results of the monitoring to a central node.

9. The method of claim 2 wherein the data collection agent comprises a network filter component inserted into a network stack to detect a connection made between entities.

10. The method of claim 2 further comprising:
determining whether an ontological communicates—with relationship exists between the indicated node and a related node of the one or more related nodes by tracking a number of connections of an application hosted by the indicated node.

11. The method of claim 2 wherein the current state of the indicated node and the related nodes in the network ontology is updated using an inference engine that makes inferences using similar nodes of the plurality of nodes.

12. The method of claim 1 wherein the indication of the at least one node is provided automatically or by a user.

13. The method of claim 1 wherein the migration group is migrated to the cloud computing infrastructure using a migration routine.

14. The method of claim 1 wherein the migration-configuration file comprises an ontology tree covering each node of the migration group.

15. The method of claim 1 wherein migrating the migration group to the cloud computing infrastructure comprises cloning a virtual image of each virtual machine being represented by a node of the migration group.

16. The method of claim 2 further comprising presenting an inventory view of the plurality of nodes to a user, the inventory view allowing the user to view a current state and a network ontology of a node of the plurality of nodes.

17. A system for migration of one or more nodes of an enterprise to a cloud infrastructure, the system comprising:
an administration console comprising a memory; and
a processor, coupled to the memory, to:
receive an indication of at least one node of a plurality of nodes to migrate from an enterprise network to a cloud computing infrastructure, the indicated node comprising a first virtual machine;
identify one or more related nodes of the plurality of nodes that have direct and indirect communication relationships with the indicated node, the related nodes comprising a second virtual machine;
generate, in view of the network ontology, a migration group comprising the indicated node and at least one node of the related nodes for the indicated node;
generate a migration configuration file for each node of the migration group, the migration-configuration file comprising service level agreement (SLA) information;
deploy a migration agent to each node of the migration group; and
migrate the migration group to a cloud infrastructure, wherein each node of the migration group is migrated using a corresponding migration-configuration file to generate an SLA for each node of the migration group with a provider of the cloud computing infrastructure in view of SLA information from the corresponding migration configuration file.

18. The system of claim 17 wherein the processor is to further determine a network ontology of the at least one node from one or more source-to-destination communication relationships during execution of one or more executables on the at least one node.

19. A non-transitory computer readable medium including instructions that, when executed by a computing device, cause the computing device to perform operations comprising:
receiving an indication of at least one node of a plurality of nodes to migrate from an enterprise network to a cloud computing infrastructure, the indicated node comprising a first virtual machine;
identifying one or more related nodes of the plurality of nodes that have direct and indirect communication relationships with the indicated node, the related nodes comprising a second virtual machine;
adding the indicated node and at least one node of the related nodes for the indicated node to a migration group;
preparing a migration-configuration file for each node of the migration group, the migration-configuration file comprising service level agreement (SLA) information;
deploying a migration agent to each node of the migration group; and
migrating the migration group to the cloud computing infrastructure, wherein each node of the migration group is migrated using a corresponding migration-configuration file to generate an SLA for each node of the migration group with a provider of the cloud computing infrastructure in view of SLA information from the corresponding migration configuration file.

20. The non-transitory computer readable medium of claim 19 wherein the one or more related nodes are identified in view of a network ontology for the indicated node, the network ontology being created for the indicated node using a data collection agent deployed to the indicated node, the network ontology describing current state of the indicated node and the related nodes.
