Abstract

Systems and method for the management of virtual machine instances are provided. A network data transmission analysis system can host virtual machine networks. A component of a hosted virtual machine network is configured in a manner to receive commands directed towards a simulated network device. The component may then execute a process or processes on the hosted virtual machine network which correspond to the received command.

Claims

1. A computer-implemented method comprising:

obtaining, via an emulated interface associated with a target component of a virtual network, a client command directed towards the target component, wherein the target component corresponds to a representation of a hardware networking device, wherein the virtual network is overlaid on a substrate network executing one or more computer systems, and wherein at least a portion of functionality attributable to the target component is implemented by the one or more computer systems of the substrate network;

causing execution of a set of substrate commands on the one or more computer systems of the substrate network to implement the portion of functionality attributable to the target component in accordance with the client command;

obtaining, from the one or more computer systems of the substrate network, a set of results responsive to the execution of the set of substrate commands, wherein the set of results responsive to the execution of the set of substrate commands are obtained from the one or more computer systems of the substrate network in lieu of instantiating the target component to execute the client command; and

generating, based at least partly on the set of results, a client result attributable to a response to the client command by the target component.

2. The computer-implemented method of claim 1, wherein network traffic routing within the substrate network is independent from network traffic routing within the virtual network.

3. The computer-implemented method of claim 1, wherein the emulated interface corresponds to a simple network management protocol (SNMP) interface or command line interface (CLI).

4. The computer-implemented method of claim 1 further comprising:

identifying the one or more computer systems of the substrate network; and

mapping the client command into the set of substrate commands in accordance with the identification of the one or more computer systems.

5. The computer-implemented method of claim 1, wherein generating the client result comprises formatting the set of results in accordance with an expected output of the logical target component.

6. The computer-implemented method of claim 1, wherein generating the client result comprises withholding a portion of information included in the set of results.

7. The computer-implemented method of claim 1 further comprising causing transmission of the client result to a client computing device where the client command originated.

8. The computer-implemented method of claim 1, wherein the emulated interface comprises one or more of an application programming interface, a user interface, or a command line interface.

9. A non-transitory computer readable storage medium storing computer executable instructions that when executed by a processor perform operations comprising:

obtaining, via an emulated interface associated with a target component of a virtual network, a client command directed towards the target component, wherein the target component corresponds to a representation of a hardware networking device, wherein the virtual network is overlaid on a substrate network, and wherein at least a portion of functionality attributable to implementation of commands by the target component is implemented by one or more physical devices of the substrate network;

obtaining, from the one or more physical devices of the substrate network, a set of results responsive to an execution of a set of substrate commands on the one or more physical devices of the substrate network to implement the portion of functionality associated with an implementation of the received client command without executing the client command, wherein the client command and the set of substrate commands are different, wherein the results responsive to the execution of the set of substrate commands are obtained from the one or more physical devices of the substrate network in lieu of instantiating the target component to execute the client command; and

generating, based at least partly on the set of results, a client result attributable to a response to the client command by the target component.

10. The non-transitory computer readable storage medium of claim 9, wherein the target component is associated with both a hardware identifier and a virtual network identifier for network traffic routing on the virtual network.

11. The non-transitory computer readable storage medium of claim 9, wherein the operations further comprise obtaining a network configuration, wherein the network configuration corresponds to at least one of the virtual network or the substrate network.

12. The non-transitory computer readable storage medium claim 11, wherein the network configuration indicates functions that can be invoked on the target component.

13. The non-transitory computer readable storage medium claim 11, wherein causing execution of the set of substrate commands further comprises sending application protocol interface (API) commands to the one or more physical devices of the substrate network.

14. The non-transitory computer readable storage medium of claim 9, wherein the operations further comprise obtaining a client configuration, wherein the client configuration facilitates interactions between a client computing system and the target component.

15. The non-transitory computer readable storage medium of claim 14, wherein creating the client result includes modifying the set of results based, at least in part, on the client configuration.

16. The non-transitory computer readable storage medium of claim 9, wherein the emulated interface comprises one or more of an application programming interface, a user interface, or a command line interface.

17. A system comprising:

at least one data store configured to at least store computer-executable instructions; and

at least one processor in communication with the data store, the processor configured to execute the computer-executable instructions to at least;

obtain, via an emulated interface associated with a target component of a virtual network, a client command towards the target component, wherein the target component corresponds to a representation of a hardware device, wherein the virtual network is overlaid on a substrate network, and wherein at least a portion of functionality attributable to the target component is implemented by one or more physical components of the substrate network; and

generate a client result attributable to a response to the client command, the client result corresponding to an outcome of an execution of a set of substrate commands on the one or more physical components of the substrate network to implement the portion of functionality attributable to the target component in accordance with the client command, wherein the outcome of the execution of the set of substrate commands are generated on the one or more physical components of the substrate network in lieu of instantiating the target component to execute the client command.

18. The system of claim 17, wherein the at least one processor is further configured to obtain configuration information related to at least one of the virtual network, the substrate network, a client computing system, or a user utilizing the client computing system.

19. The system of claim 18, wherein the at least one processor is further configured to determine the set of substrate commands based, at least in part, on the configuration information.
