Dynamic resource configuration system and method for distributed computing environments
A dynamic resource configuration system that includes a computer executed application that receives, from resource of the distributed computing environment, a network configuration request message to dynamically configure one or more network parameters of the resource. In response, the application obtains a unique identity of the resource using the received network configuration request message, obtains customized configuration parameters for the resource using the obtained unique identity, and configures the resource using the customized configuration parameters.

obtain a unique identity of the resource using the received network configuration request message;
receive a null message in response to a first resource information record request based on the unique identity of the resource;
assign a temporary Internet Protocol (IP) address to the resource in response to receiving the null message;
transmit, after receiving the null message and to the resource using the assigned temporary IP address, a second resource information record request;
obtain, from the resource and based on the second resource information record request, resource information comprising customized configuration parameters for the resource and characteristic information for the resource;
replace the temporary IP address with a new IP address based on the resource information;
select a preboot execution environment (PXE) server from among a plurality of PXE servers, the selected PXE server to be used for configuration of the resource by applying the customized configuration parameters to the resource in accordance with one or more customization policies; and
communicate with the selected PXE server to configure the resource using the customized configuration parameters.
2. The dynamic resource configuration system of claim 1 , wherein the network configuration request message comprises a dynamic host configuration protocol (DHCP) message.
3. The dynamic resource configuration system of claim 2 , wherein the computer-readable instructions are executed to obtain the unique identity of the resource by reading a media access control (MAC) address included in the network configuration request message, the MAC address uniquely identifying a communication interface of the resource.
4. The dynamic resource configuration system of claim 3 , wherein the computer-readable instructions are executed to obtain the customized configuration parameters by accessing a record stored in the at least one memory, the record associating the MAC address with the customized configuration parameters, the customized configuration parameters included in the record.
5. The dynamic resource configuration system of claim 1 , wherein the customized configuration parameters comprise a specified range of network addresses to be assigned to the resource.
6. The dynamic resource configuration system of claim 5 , wherein the computer-readable instructions are executed to determine the specified range of network addresses by comparing one or more applications deployed on the resource with a policy, stored in the at least one memory, indicating the specified range of network addresses to be associated with the one or more applications.
7. The dynamic resource configuration system of claim 1 , wherein the computer-readable instructions are executed to call a script to obtain the customized configuration parameters for the resource, the script deployed independently of when the dynamic resource configuration system is deployed.
8. A dynamic resource configuration method comprising:
receiving, using instructions stored in a non-transitory, computer-readable medium and executed on at least one processor, a network configuration request message to configure one or more network parameters of a resource;
obtaining, using the instructions executed on the at least one processor, a unique identity of the resource using the received network configuration request message;
receiving, using the instructions executed on the at least one processor, a null message in response to a first resource information record request based on the unique identity of the resource;
assigning, using the instructions executed on the at least one processor, a temporary Internet Protocol (IP) address to the resource in response to receiving the null message;
transmitting, after receiving the null message and to the resource using the assigned temporary IP address, a second resource information record request;
obtaining, from the resource and using the assigned temporary IP address, resource information comprising customized configuration parameters for the resource and characteristic information for the resource;
replacing, using the instructions executed on the at least one processor, the temporary IP address with a new IP address based on the resource information;
selecting, using the instructions executed on the at least one processor, a preboot execution environment (PXE) server from among a plurality of PXE servers, the selected PXE server to be used for configuration of the resource by applying the customized configuration parameters to the resource in accordance with one or more customization policies; and
communicating, using the instructions executed on the at least one processor, with the selected PXE server to configure the resource using the customized configuration parameters.
9. The dynamic resource configuration method of claim 8 , wherein the network configuration request message comprises a dynamic host configuration protocol (DHCP) message.
10. The dynamic resource configuration method of claim 9 , further comprising obtaining the unique identity of the resource by reading a media access control (MAC) address included in the network configuration request message, the MAC address uniquely identifying a communication interface of the resource.
11. The dynamic resource configuration method of claim 10 , further comprising obtaining the customized configuration parameters by accessing a record stored in at least one memory, the record associating the MAC address with the customized configuration parameters, the customized configuration parameters included in the record.
12. The dynamic resource configuration method of claim 8 , wherein the customized configuration parameters comprise a specified range of network addresses to be assigned to the resource.
13. The dynamic resource configuration method of claim 12 , further comprising determining the specified range of network addresses by comparing one or more applications deployed on the resource with a policy indicating the specified range of network addresses to be associated with the one or more applications.
14. The dynamic resource configuration method of claim 8 , further comprising executing a script to obtain the customized configuration parameters for the resource, the script deployed independently of when a dynamic resource configuration system is deployed.
15. A non-transitory computer readable medium comprising computer executable instructions that, when executed by at least one processor, cause the at least on processor to:
receive a network configuration request message to configure one or more network parameters of a resource;
obtain a unique identity of the resource using the received network configuration request message;
receive a null message in response to a first resource information record request based on the unique identity of the resource;
assign a temporary Internet Protocol (IP) address to the resource in response to receiving the null message;
transmit, after receiving the null message and to the resource using the assigned temporary IP address, a second resource information record request;
obtain, from the resource and based on the second resource information record request, resource information comprising customized configuration parameters for the resource and characteristic information for the resource;
