Abstract

Embodiments of the present invention provide systems and methods for constructing a plan for creating a cloud service. In one embodiment, a configurator receives a request for one or more services making up a cloud service, and a preliminary plan for the requested services is generated. A service provider determines that it is able to fulfill a requested service, and inserts a sub plan for fulfilling the requested service into the preliminary plan. A final plan is generated, which includes a sub plan from each service provider inserted into the preliminary plan.

First claim

What is claimed is:

1 . A method for constructing a plan for creating a cloud service, the method comprising the steps of:
receiving, at a configurator, a request for a cloud service, wherein the cloud service comprises one or more services, and wherein one or more service providers are configured to perform the one or more services; generating, by the configurator, a first plan, wherein the first plan comprises workflow steps representing the one or more services; sending, by the configurator, the first plan comprising a message associated with a first workflow step topic to a bus; determining whether a first service provider is able to execute the first workflow step topic; responsive to determining that the first service provider is able to execute the first workflow step topic, inserting, by the first service provider, a sub plan, into the first workflow step topic; and generating a final plan, wherein the final plan comprises one or more sub plans inserted into substantially all of the workflow steps of the first plan.

2 . The method of claim 1 , further comprising:
requesting, by an orchestrator, execution of the final plan by at least one of the one or more service providers associated with the one or more services.

3 . The method of claim 2 , wherein the final plan is unknown prior to execution of the final plan by at least one of the one or more service providers associated with the one or more services.

4 . The method of claim 1 , further comprising:
inserting, by an orchestrator, traceability information between at least two of the workflow steps representing the one or more services of the final plan.

5 . The method of claim 4 , wherein the traceability information is configured to locate an error or a failure during execution of the final plan.

6 . The method of claim 1 , further comprising:
determining whether a second service provider is able to execute a second workflow step topic; responsive to determining that the second service provider is able to execute the second workflow step topic, inserting, by the second service provider, another sub plan into the second workflow step topic; and sending, by the second service provider, a message to the bus, wherein the message comprises another workflow step topic associated with the workflow steps.

7 . The method of claim 1 , further comprising:
receiving, by a last service provider from the one or more service providers, an end message, wherein the end message indicates complete construction of the final plan.

8 . A computer program product comprising:
a computer readable storage medium and program instructions stored on the computer readable storage medium, the program instructions comprising: program instructions to receive, at a configurator, a request for a cloud service, wherein the cloud service comprises one or more services, and wherein one or more service providers are configured to perform the one or more services; program instructions to generate, by the configurator, a first plan, wherein the first plan comprises workflow steps representing the one or more services; program instructions to send, by the configurator, the first plan comprising a message associated with a first workflow step topic to a bus; program instructions to determine whether a first service provider is able to execute the first workflow step topic; program instructions to, responsive to determining that the first service provider is able to execute the first workflow step topic, insert, by the first service provider, a sub plan, into the first workflow step topic; and program instruction to generate a final plan, wherein the final plan comprises one or more sub plans inserted into substantially all of the workflow steps of the first plan.

9 . The computer program product of claim 8 , further comprising:
program instructions to request, by an orchestrator, execution of the final plan by at least one of the one or more service providers associated with the one or more services.

10 . The computer program product of claim 9 , wherein the final plan is unknown prior to execution of the final plan by at least one of the one or more service providers associated with the one or more services.

11 . The computer program product of claim 8 , further comprising:
program instructions to insert, by an orchestrator, traceability information between at least two of the workflow steps representing the one or more services of the final plan.

12 . The computer program product of claim 11 , wherein the traceability information is configured to locate an error or a failure during execution of the final plan.

13 . The computer program product of claim 8 , further comprising:
program instructions to determine whether a second service provider is able to execute a second workflow step topic; program instructions to, responsive to determining that the second service provider is able to execute the second workflow step topic, insert, by the second service provider, another sub plan into the second workflow step topic; and program instructions to send, by the second service provider, a message to the bus, wherein the message comprises another workflow step topic associated with the workflow steps.

14 . A computer system comprising:
one or more computer processors; one or more computer readable storage media; program instructions stored on the one or more computer readable storage media for execution by at least one of the one or more processors, the program instructions comprising: program instructions to receive, at a configurator, a request for a cloud service, wherein the cloud service comprises one or more services, and wherein one or more service providers are configured to perform the one or more services; program instructions to generate, by the configurator, a first plan, wherein the first plan comprises workflow steps representing the one or more services; program instructions to send, by the configurator, the first plan comprising a message associated with a first workflow step topic to a bus; program instructions to determine whether a first service provider is able to execute the first workflow step topic; program instructions to, responsive to determining that the first service provider is able to execute the first workflow step topic, insert, by the first service provider, a sub plan, into the first workflow step topic; and program instruction to generate a final plan, wherein the final plan comprises one or more sub plans inserted into substantially all of the workflow steps of the first plan.

15 . The computer system of claim 14 , further comprising:
program instructions to request, by an orchestrator, execution of the final plan by at least one of the one or more service providers associated with the one or more services.

16 . The computer system of claim 15 , wherein the final plan is unknown prior to execution of the final plan by at least one of the one or more service providers associated with the one or more services.

17 . The computer system of claim 14 , further comprising:
program instructions to insert, by an orchestrator, traceability information between at least two of the workflow steps representing the one or more services of the final plan.

18 . The computer system of claim 17 , wherein the traceability information is configured to locate an error or a failure during execution of the final plan.

19 . The computer system of claim 14 , further comprising:
program instructions to determine whether a sec
