Abstract

A system is disclosed for managing configuration drift of computing resource instances, including instructions to (1) receive a definition of a plurality of functional roles to be played by resource instances within a multi-resource computing system; (2) select, for each of the roles, a designated exemplar from the group of resource instances playing that role; (3) capture characteristics of that designated exemplar and assign the captured characteristics to a functional role template; and (4) during operation, measure configuration drift by comparing resource instances for each functional role to the functional role template associated with that role, such measuring being independent of any comparing to resource instances in the functional role.

First claim

The invention claimed is:

1. A method of managing configuration drift in a multi-resource computing system, comprising:
defining a plurality of functional roles to be played by resource instances within the multi-resource computing system;
identifying, for a first functional role of the plurality of functional roles, a group of resource instances for carrying out the first functional role;
for the first functional role, selecting a designated exemplar from the group of resource instances;
capturing a first plurality of characteristics of the designated exemplar;
assigning the captured first plurality of characteristics to a first functional role template for the first functional role;
specifying a first characteristic of the first functional role template as a triggering characteristic;
specifying a predefined change amount for the triggering characteristic;
during operation of the multi-resource computing system, measuring configuration drift by comparing resource instances for the first functional role to the first functional role template;
in response to a detection of the predefined change amount for the triggering characteristic:
selecting a second designated exemplar from the group of resource instances;
capturing a second plurality of characteristics of the second designated exemplar; and
automatically generating a second functional role template for the first functional role using the second plurality of characteristics.

2. The method of claim 1 , where the predefined change amount for the triggering characteristic is associated with an improved efficiency for the first functional role.

3. The method of claim 1 , further comprising using the second functional role template to measure configuration drift in resource instances associated with the first functional role.

4. The method of claim 1 , where the predefined change amount for the triggering characteristic is associated with a reduced equipment expense for the first functional role.

5. The method of claim 1 , where the predefined change amount for the triggering characteristic is associated with an improved maintenance for the first functional role.

6. The method of claim 1 , where the predefined change amount for the triggering characteristic is associated with an improved installation for the first functional role.

7. The method of claim 1 , where the predefined change amount for the triggering characteristic is indicative of file corruption in a database file structure.

8. The method of claim 1 , where the measuring is performed at different time intervals for different characteristics in the first plurality of characteristics of the first functional role template.

9. The method of claim 1 , where selecting the designated exemplar includes selecting multiple resource instances from the group of resource instances so that a multiple-instance grouping serves as the designated exemplar.

10. A system for managing configuration drift, comprising:
a processor;
a storage device containing instructions executable by the processor to:
receive a definition of functional roles to be played by resource instances within a multi-resource computing system;
receive, for a first functional role of the functional roles, an identification of a group of resource instances for carrying out the first functional role;
select, for the first functional role of the functional roles, a designated exemplar from the group of resource instances;
capture a first plurality of characteristics of the designated exemplar;
assign the captured first plurality of characteristics to a first functional role template for the first functional role;
specify a first characteristic of the first functional role template as a triggering characteristic;
specify a predefined change amount for the triggering characteristic;
during operation of the multi-resource computing system, measure configuration drift by comparing resource instances for the first functional role to the first functional role template; and
in response to a detection of the predefined change amount in the triggering characteristic:
select a second designated exemplar;
capture a second plurality of characteristics of the second designated exemplar; and
automatically generate a second functional role template for the first functional role using the second plurality of characteristics.

11. The system of claim 10 , where the predefined change amount for the triggering characteristic is associated with an improved efficiency for the first functional role.

12. The system of claim 10 , where the predefined change amount for the triggering characteristic is associated with a reduced equipment expense for the first functional role.

13. The system of claim 10 , where the predefined change amount for the triggering characteristic is indicative of file corruption in a database file structure.

14. The system of claim 10 , where to select the designated exemplar, the instructions are executable to select multiple resource instances from the group of resource instances so that a multiple-instance grouping serves as the designated exemplar.

15. A non-transitory machine-readable storage medium storing instructions executable by a processor to:
receive a definition of functional roles to be played by resource instances within a multi-resource computing system;
receive, for a first functional role of the functional roles, an identification of a group of resource instances for carrying out the first functional role;
select, for the first functional role of the functional roles, a designated exemplar from the group of resource instances;
capture a first plurality of characteristics of the designated exemplar;
assign the captured first plurality of characteristics to a first functional role template for the first functional role;
specify a first characteristic of the first functional role template as a triggering characteristic;
specify a predefined change amount for the triggering characteristic;
during operation of the multi-resource computing system, measure configuration drift by comparing resource instances for the first functional role to the first functional role template; and
in response to a detection of the predefined change amount in the triggering characteristic:
select a second designated exemplar from the group of resource instances, the second designated exemplar different from the designated exemplar;
capture a second plurality of characteristics of the second designated exemplar;
automatically generate a second functional role template for the first functional role using the second plurality of characteristics.

16. The storage medium of claim 15 , where the predefined change amount for the triggering characteristic is associated with an improved efficiency for the first functional role.

17. The storage medium of claim 15 , where the predefined change amount for the triggering characteristic is associated with a reduced equipment expense for the first functional role.

18. The storage medium of claim 15 , where the predefined change amount for the triggering characteristic is associated with an improved maintenance for the first functional role.

19. The storage medium of claim 15 , where the predefined change amount for the triggering characteristic is indicative of file corruption in a database file structure.

20. The storage medium of claim 15 , where to select the designated exemplar, the instructions are executable to select multiple resource instances from the group of resource i
