Autonomic control of a distributed computing system using dynamically assembled resource chains

A method comprising:

• receiving input that defines a service-level agreement;
• receiving monitoring data that indicates a current service level of a flux service provided by a distributed computing system, wherein the flux service is a top-level service that represents a defined set of functionalities;
• determining whether the current service level of the flux service satisfies the service-level agreement;
• assembling dynamically, with one or more processors, a resource chain when it is determined that the current service level of the flux service does not satisfy the service-level agreement;
• assembling resources in the resource chain according to a cost associated with each resource, wherein at least one of the resources is a functioning resource and the cost associated with the at least one of the resources is determined according to whether the at least one of the resources is currently operating in another resource chain;
• wherein a resource chain is a set of resources that are ordered by a relation specifying that a first resource provides a service to a second resource,
• wherein the resource chain includes a first resource of the distributed computing system and one or more interpreting resources of the distributed computing system,
• wherein the first resource is a resource capable of providing the flux service and the interpreting resources are resources capable of providing interpretation services, wherein each of the interpretation services represents a defined set of functionalities provided to another service within the distributed computing system, and
• wherein, when the resources in the resource chain are operating, the resource chain provides the flux service, thereby enhancing the service level of the flux service.

A non-transitory computer-readable storage medium comprising instructions, wherein the instructions cause a programmable processor to:

• receive input that defines a service-level agreement;
• receive monitoring data that indicates a current service level of a flux service provided by a distributed computing system, wherein the flux service is a top-level service that represents a defined set of functionalities;
• determine whether the current service level of the flux service satisfies the service-level agreement;
• assemble dynamically a resource chain when it is determined that the current service level of the flux service does not satisfy the service-level agreement,
• wherein a resource chain is a set of resources that are ordered by a relation specifying that a first resource provides a service to a second resource,
• wherein the resource chain includes a first resource of the distributed computing system and one or more interpreting resources of the distributed computing system,
• wherein the first resource is a resource capable of providing the flux service and the interpreting resources are resources capable of providing interpretation services, wherein each of the interpretation services represents a defined set of functionalities provided to another service within the distributed computing system, and
• wherein resources in the resource chain are assembled according to a cost associated with each resource, wherein at least one of the resources is a functioning resource and the cost associated with the at least one of the resources resource is determined according to whether the at least one of the resources is currently operating in another resource chain, and
• wherein, when the resources in the resource chain are operating, the resource chain provides the flux service, thereby enhancing the service level of the flux service.
