Abstract

A system and methods for modeling and analyzing Quality of Service (QoS) characteristics of federated cloud services in an open eco-system is disclosed. A plurality of system entities of a federated service system are identified, and each of the system entities is classified to provide a plurality of entity classifications. A plurality of inter-entity relationships of the system entities are identified, and each of the inter-entity relationships is classified as a primitive model to provide a plurality of inter-entity relationship classifications. A composite model of the federated service system comprising the system entities, the entity classifications, the inter-entity relationships, and the inter-entity relationship classifications is generated.

Claims

1. A method for modeling and analyzing Quality of Service (QoS) characteristics of federated cloud services in an open eco-system, the method comprising:

identifying a plurality of system entities of a federated service system;

classifying each of the system entities to provide a plurality of entity classifications;

identifying a plurality of inter-entity relationships of the system entities;

classifying each of the inter-entity relationships as a primitive model to provide a plurality of inter-entity relationship classifications; and

generating a composite model of the federated service system comprising the system entities, the entity classifications, the inter-entity relationships, and the inter-entity relationship classifications.

2. The method according to claim 1, wherein the entity classifications comprise one of:

a service, a host and a network segment.

3. The method according to claim 1, wherein the inter-entity relationship classifications comprise at least one member selected from the group consisting of:

a service usage functional relationship, a service usage temporal relationship, a hosting relationship, and a connection relationship.

4. The method according to claim 1, further comprising recursively applying one or more primitive models to the federated service system to provide the composite model.

5. The method according to claim 4, further comprising recursively decomposing the composite model into a composite model graph comprising the one or more primitive models and representing the federated service system.

6. The method according to claim 5, further comprising:

defining a workload model for at least one federated service of the federated service system, wherein a root of the composite model graph represents a starting point of a workload imposed on the at least one federated service by at least one end user; and

decomposing the workload recursively from a parent node to at least one child node.

7. The method according to claim 1, further comprising calculating QoS characteristics by applying an evaluation and derivation method to the composite model.

8. The method according to claim 7, further comprising reporting the QoS characteristics of the composite model.

9. The method according to claim 1, further comprising representing the composite model in XML based on a primitive model XML schema specification to provide an XML composite model.

10. A Quality of Service (QoS) characteristics modeling and analysis system for federated cloud services, the system comprising:

a system entity identification module operable to identify a plurality of system entities of a federated service system;

an inter-entity relationship identification module operable to identify a plurality of inter-entity relationships of the system entities;

a classification module operable to;

classify each of the system entities to provide a plurality of entity classifications; and

classify each of the inter-entity relationships as a primitive model to provide a plurality of inter-entity relationship classifications; and

a compositing module operable to generate a composite model of the federated service system comprising the system entities, the entity classifications, the inter-entity relationships, and the inter-entity relationship classifications.

11. The system according to claim 10, wherein the entity classifications comprise one of:

a service, a host and a network segment.

12. The system according to claim 10, wherein the inter-entity relationships comprise at least one member selected from the group consisting of:

a service usage functional relationship, a service usage temporal relationship, a hosting relationship, and a connection relationship.

13. The system according to claim 10, further comprising an evaluation and derivation module operable to evaluate and derive QoS characteristics of the composite model.

14. The system according to claim 10, wherein the compositing module is further operable to represent the composite model in XML based on a primitive model XML schema specification to provide an XML composite model.

15. The system according to claim 10, wherein the compositing module is further operable to recursively apply one or more primitive models to generate the composite model.

16. The system according to claim 15, wherein the compositing module is further operable to recursively decompose the composite model into a composite model graph comprising the primitive models and representing the federated service system.

17. The system according to claim 16, wherein the compositing module is further operable to:

define a workload model for the federated service system, wherein a root of the composite model graph represents a starting point of a workload imposed on the federated service system by an end user; and

decompose the workload recursively from a parent node to a child node.

18. A computer readable storage medium comprising computer-executable instructions for performing a method for modeling and analyzing Quality of Service (QoS) characteristics of federated cloud services in an open eco-system, the method executed by computer-executable instructions comprising:

identifying a plurality of system entities of a federated service system;

classifying each of the system entities to provide a plurality of entity classifications;

identifying a plurality of inter-entity relationships of the system entities;
