Abstract

A method and apparatus for dynamic adaptation of a configuration to a system environment. An embodiment of a method includes obtaining system information for a system. The system information is stored in a memory. A setting of an abstract configuration for the system is resolved, with the resolution of the setting being based at least in part on the system information.

Claims

1. A method comprising:

receiving a virtual configuration that includes an abstract ent resolvable to a specific element,

the receiving being from a first system and performed by a second system,

the virtual configuration being generated by the first system based on an abstract configuration accessed by the first system, on a customization specific to multiple systems that include the second system, and on a use case applicable to the second system,

the abstract configuration including a set of abstract elements that includes the abstract element resolvable to the specific element,

the customization being a version of the abstract configuration,

the use case being a version of the customization,

the specific element corresponding to the second system and being derivable based on the abstract element and on a system context of the second system;

resolving the abstract element to the specific element by deriving the specific element based on the abstract element and on the system context of the second system,

the resolving being performed by a configuration resolver that is included in a configuration machine embodied in the second system; and

storing the virtual configuration in a memory of the second system.

2. The method of claim 1, wherein the resolving of the abstract element to the specific element occurs at a run-time of a task that is associated with the virtual configuration.

3. The method of claim 1, wherein the virtual configuration is generated by the first system based on the system context of the second system, the system context of the second system being accessible by the first system.

4. The method of claim 1, wherein the virtual configuration is generated by the first system based on a use case that is applicable to the second system, the use case being a version of the abstract configuration and accessible by the first system.

5. The method of claim 4, wherein the use case includes a number, the number representing a quantity of nodes to be turned on in accordance with the use case.

6. The method of claim 1, wherein the customization and the use case are accessible by the first system.

7. The method of claim 1, wherein the resolving of the abstract element to the specific element includes obtaining a value pertinent to the abstract element from an operating system that is executing on the second system.

8. A system comprising:

a memory configured to store a virtual configuration that includes an abstract element resolvable to a specific element,

the virtual configuration being generated by a further system based on an abstract configuration accessed by the further system, on a customization specific to multiple systems that include the system, and on a use case applicable to the system,

the abstract configuration including a set of abstract elements that includes the abstract element resolvable to the specific element,

the customization being a version of the abstract configuration,

the use case being a version of the customization,

the specific element corresponding to the system and being derivable based on the abstract element and on a system context of the system; and

a configuration engine configured to;

receive the virtual configuration from the further system;

resolve the abstract element to the specific element by deriving the specific element based on the abstract element and on the system context of the system; and

store the virtual configuration in the memory.

9. The system of claim 8, wherein the configuration engine is configured to resolve the abstract element to the specific element at a run-time of a task that is associated with the virtual configuration.

10. The system of claim 8, wherein the virtual configuration is generated by the further system based on the system context of the system, the system context of the system being accessible by the further system.

11. The system of claim 8, wherein the virtual configuration is generated by the further system based on a use case that is applicable to the system, the use case being a version of the abstract configuration and accessible by the further system.

12. The system of claim 11, wherein the use case includes a number, the number representing a quantity of nodes to be turned on in accordance with the use case.

13. The system of claim 8, wherein the customization and the use case are accessible by the further system.

14. The system of claim 8, wherein the configuration engine, in resolving the abstract element to the specific element, is configured to obtain a value pertinent to the abstract element from an operating system that is executing on the system.

15. The system of claim 14, wherein the configuration engine, in resolving the abstract element to the specific element, is configured to modify the value obtained from the operating system.

16. The system of claim 14, wherein the configuration engine, in resolving the abstract element to the specific element, is configured to query the system context of the system based on the abstract element.
