Abstract

An invention is provided for creating logical network abstractions of physical networks, and deploying computer services to physical networks based on a specified logical network. In an embodiment, a physical network is divided into one or more logical networks. Upon receiving an indication to deploy a computer service to a logical network, a mapping from that logical network to a sub-network of the physical network is determined, the service is configured to execute on the sub-network of the physical network, and an indication of this configuration of the service is stored.

Claims

1. A method, comprising:

receiving, by one or more computers, an indication of a logical network for a computer service, the computer service to communicate via a physical network;

determining, by the one or more computers, a sub-network of the physical network based on determining a virtual local network identifier (VLAN ID) of the logical network, and determining that a host of the sub-network is configured to communicate with the VLAN ID of the logical network;

configuring, by the one or more computers, the service to communicate via the sub-network; and

saving, by the one or more computers, an indication of the configured service in a memory.

2. The method of claim 1, further comprising:

determining that the service is to communicate via a second physical network, and based on the logical network;

determining a second sub-network of the second physical network based on determining a VLAN ID of the second logical network, and determining that a host of the second sub-network is configured to communicate with the VLAN ID of the second logical network;

configuring the service to communicate via the second sub-network; and

saving an indication of the re-configured service in a memory.

3. The method of claim 1, further comprising:

receiving an indication of a second logical network for a computer service, the computer service to communicate via the physical network;

determining a second sub-network of the physical network based on determining that a host of the second sub-network is configured to communicate with the VLAN ID of the logical network;

configuring the service to communicate via the second sub-network; and

saving an indication of the re-configured service in a memory.

4. The method of claim 1, wherein receiving the indication of the logical network for the computer service comprises:

receiving an indication of a second logical network for the computer service; and

further comprising;

determining a second sub-network of the physical network based on the second logical network; and

configuring the service to communicate on the second sub-network as well as the sub-network.

5. The method of claim 1, wherein the sub-network comprises an Internet Protocol (IP) address and an associated subnet mask.

6. The method of claim 1, wherein determining a sub-network of the physical network based on the logical network comprises:

determining information about the host of the physical network based on information stored by a router of the physical network.

7. The method of claim 6, wherein the information about the host comprises:

an Internet Protocol (IP) address of the host.

8. The method of claim 6, wherein the information about the host comprises:

a VLAN ID of the host.

9. The method of claim 1, wherein a logical network comprises:

a permission to access a resource.

10. The method of claim 1, wherein a logical network comprises:

an amount of network bandwidth available via the logical network.

11. A system, comprising:

a memory bearing instructions that, upon execution by a processor, cause the system to at least;

receive an indication of a logical network for a computer service, the computer service to communicate via a physical network;

determine a sub-network of the physical network based on determining a virtual local network identifier (VLAN ID) of the logical network, and determining that a host of the sub-network is configured to communicate with the VLAN ID of the logical network; and

configure the service to communicate via the sub-network.

12. The system of claim 11, wherein the instructions that, upon execution by the processor, cause the system to at least configure the service to communicate via the sub-network further cause the system to at least:

select a machine for the service to execute upon from a plurality of machines on the sub-network based on a load of the machine.

13. The system of claim 11, wherein the memory further bears instructions that, upon execution by the processor, cause the system to at least:

determine that the sub-network has changed; and

update a correlation between the sub-network and the logical network based on the change to the sub-network.

14. The system of claim 11, wherein the memory further bears instructions that, upon execution by the processor, cause the system to at least:

determining that the service is to communicate via a second physical network, and based on the logical network;

determining a second sub-network of the second physical network based on determining that a host of the second sub-network is configured to communicate with a VLAN ID of the second logical network;

configuring the service to communicate via the second sub-network; and

saving an indication of the re-configured service in a memory.

15. The system of claim 11, wherein the memory further bears instructions that, upon execution by the processor, cause the system to at least:

receiving an indication of a second logical network for a computer service, the computer service to communicate via the physical network;

determining a second sub-network of the physical network based on determining that a host of the second sub-network is configured to communicate with the VLAN ID of the logical network;

configuring the service to communicate via the second sub-network; and

saving an indication of the re-configured service in a memory.

16. The system of claim 11, wherein the instructions that, upon execution by the processor, cause the system to at least receive the indication of the logical network for the computer service further cause the system to at least comprises:

receive an indication of a second logical network for the computer service; and

wherein the memory further bears instructions that, upon execution by the processor, cause the system to at least;

determine a second sub-network of the physical network based on the second logical network; and

configure the service to communicate on the second sub-network as well as the sub-network.

17. A computer-readable storage medium bearing computer-readable instructions that, upon execution by a computer, cause the computer to perform operations comprising:

receiving an indication of a logical network for a computer service, the computer service to communicate via a physical network;

determining a sub-network of the physical network based on determining a virtual local network identifier (VLAN ID) of the logical network, and determining that a host of the sub-network is configured to communicate with the VLAN ID of the logical network; and

configuring the service to communicate via the sub-network.

18. The computer-readable storage medium of claim 17, wherein determining a sub-network of the physical network based on the logical network comprises:

determining information about the host of the physical network based on information stored by a router of the physical network.

19. The computer-readable storage medium of claim 17, wherein configuring the service to communicate via the sub-network further comprises:

selecting a machine for the service to execute upon from a plurality of machines on the sub-network based on a load of the machine.

20. The computer-readable storage medium of claim 17, further bearing computer-readable instructions that, upon execution by the computer, cause the computer to perform operations comprising:

determining that the sub-network has changed; and
