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, across a plurality of sites, an indication of a first and second logical network for a computer service, the computer service to communicate via a first or second physical network;

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

determining, at a second one of the plurality of sites, by the one or more computers, a second sub-network of the second physical network and a second host of the second sub-network based on determining a VLAN ID of the second logical network, and determining that the second host of the second sub-network is configured to communicate with the VLAN ID of the second logical network;

configuring, by the one or more computers, the computer service to execute on the first or second host and to communicate via the first or second sub-network based on determining movement of the computer service to the first or second site; and

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

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

3. The method of claim 1, wherein determining the first and second sub-network of the first and second physical network based on the first and second logical network comprises:

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

4. The method of claim 3, wherein the information about the first and second host comprises:

an Internet Protocol (IP) address of the first and second host.

5. The method of claim 3, wherein the information about the first and second host comprises:

a VLAN ID of the first and second host.

6. The method of claim 1, wherein the first and second logical network comprises:

a permission to access a resource.

7. The method of claim 1, wherein the first and second logical network comprises:

an amount of network bandwidth available via the first and second logical network.

8. A system, comprising:

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

receive, across a plurality of sites, an indication of a first and second logical network for a computer service, the computer service to communicate via a first or second physical network;

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

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

configure the computer service to execute on the first or second host and to communicate via the first or second sub-network based on determining movement of the computer service to the first or second site.

9. The system of claim 8, wherein the instructions that, upon execution by the processor, cause the system to at least configure the computer service to communicate via the first or second sub-network further cause the system at least to:

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

10. The system of claim 8, wherein the memory further bears instructions that, upon execution by the processor, cause the system at least to:

determine that the first or second sub-network has changed; and

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

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

receiving, across a plurality of sites, an indication of a first and second logical network for a computer service, the computer service to communicate via a first or second physical network;

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

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

configuring the computer service to execute on the first or second host and to communicate via the first or second sub-network based on determining movement of the computer service to the first or second site.

12. The computer-readable storage device of claim 11, wherein determining the first and second sub-network of the first and second physical network based on the first and second logical network comprises:

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

13. The computer-readable storage device of claim 11, wherein configuring the computer service to communicate via the first or second sub-network further comprises:

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

14. The computer-readable storage device of claim 11, further bearing computer-readable instructions that, upon execution by the computer, cause the computer to perform operations comprising:

determining that the first or second sub-network has changed; and

updating a correlation between the first or second sub-network and the first or second logical network based on the change to the first or second sub-network.
