Adaptive resource management method
First Claim
1. In a data processing structure with a distributed architecture including a plurality of subject entities and at last one authority entity, a resource management method for configuring the subject entities, each subject entity belonging to at least one of a plurality of categories and controlling an instance of at least one resource, the at least one authority entity defining a target state of the resources, wherein the method includes the steps of:
- publishing, under the control of the at least one authority entity, a plurality of rules each one including an indication of the target state of a resource for a category of the subject entities,each subject entity performing a self-configuration of itself by (i) retrieving the rules corresponding to the at least one category of the subject entity, and (ii) applying each retrieved rule to self-configure the subject entity according to the target state indicated in the rule,storing an indication of the rules applied on the subject entity; and
periodically re-applying the applied rules,wherein the step of applying each retrieved rule includes;
(i) detecting a current state of the instance of the resource indicated in the retrieved rule,(ii) determining at least one management action required to bring the instance of the resource from the current state to the target state indicated in the retrieved rule, and(iii) executing the at least one management action.

Abstract
A resource management method (400c) and a corresponding system implementing an adaptive model are proposed. The method allows an authority to define a desired target state of several kinds of resources, which are directly controlled by different subjects. The authority publishes (460) a series of rules in a shared repository; each rule indicates the target state of a resource for a corresponding category of the subjects. Each subject retrieves (444-456;462-468) the rules corresponding to its category from the shared repository. The rules are then applied (458;469) by the subject directly. In this way, the subjects self-adapt to the rules, without requiring any direct interaction with the authority.

6. In a data processing structure with a distributed architecture including a plurality of subject entities and at least one authority entity, a method performed by a computer program directly loadable into a working memory of a computer of an authority entity for performing a resource management method for configuring the subject entities when the program is run on the computer, each subject entity belonging to at least one of a plurality of categories and controlling an instance of at least one resource, the at least one authority entity defining a target state of the resources, wherein the method includes the steps of:
-
publishing a plurality of rules each one including an indication of the target state of a resource for a category of the subject entities, for causing each subject entity to perform a self-confirguration of itself by (i) retrieving the rules corresponding to the at least one category of the subject entity and (ii) applying each retrieved rule to self-configure the subject entity according to the target state indicated in the rule, storing an indication of the rules applied on the subject entity, and periodically re-applying the applied rules, wherein the step of applying each retrieved rule includes; (i) detecting a current state of the instance of the resource indicated in the retrieved rule, (ii) determining at least one management action required to bring the instance of the resource from the current state to the target state indicated in the retrieved rule, and (iii) executing the at least one management action.

7. In a data processing structure with a distributed architecture including a plurality of subject entities and at last one authority entity, a method performed by a computer program directly loadable into a working memory of a computer of a subject entity for performing a resource management method for configuring the subject entity when the program is run on the computer, each subject entity belonging to at least one of a plurality of categories and controlling an instance of at least one resource, the at least one authority entity defining a target state of the resources by publishing a plurality of rules each one including an indication of the target state of a resource for a category of the subject entities, wherein the method includes the steps, which are performed by each subject entity, of:
-
retrieving the rules corresponding to the at least one category of the subject entity, applying each retrieved rule to self-configure the subject entity according to the target state indicated in the rule, storing an indication of the rules applied on the subject entity, and periodically re-applying the applied rules, wherein the step of applying each retrieved rule includes; (i) detecting a current state of the instance of the resource indicated in the retrieved rule, (ii) determining at least one management action required to bring the instance of the resource from the current state to the target state indicated in the retrieved rule, and (iii) executing the at least one management action.
