Abstract

Embodiments of the present disclosure dynamically generate solution stacks. In one embodiment, a request to deploy a service in a cloud computing environment is received. A service repository is queried for data that describes one or more requirements of the service. One or more prerequisite services are identified based, at least in part, on the requirements of the service. A solution stack model is dynamically generated from (i) a stack service model of the service and (ii) the one or more prerequisite services, wherein the solution stack model is based, at least in part, on the requirements of the service.

First claim

What is claimed is:

1. A method comprising:
receiving, by one or more computer processors, a request to deploy a service in a cloud computing environment;
querying, by one or more computer processors, a service repository for data that describes one or more requirements of the service;
identifying, by one or more computer processors, one or more prerequisite services based, at least in part, on the requirements of the service; and
dynamically generating, by one or more computer processors, a solution stack model from (i) a stack service model of the service and (ii) the one or more prerequisite services, wherein the solution stack model is based, at least in part, on the requirements of the service and wherein the service and the one or more prerequisite services execute concurrently via the cloud computing environment in accordance with the requirements of the service, and wherein dynamically generating a solution stack model comprises:
interweaving, by one or more computer processors, one or more life cycle actions of the one or more prerequisite services with one or more life cycle actions of the service based, at least in part, on a plurality of life cycle ordering rules, wherein (i) for each of the one or more prerequisite services and the service, the one or more life cycle actions are sequential, (ii) each life cycle action is associated with a respective indicator of a plurality of indicators, and (iii) wherein the plurality of life cycle ordering rules comprise:
a first life cycle ordering rule that causes each life cycle action that is associated with a skip indicator of the plurality of indicators to be skipped; and
a second life cycle ordering rule causes, for each indicator of the plurality of indicators that (i) is not the skip indicator and (ii) is associated with more than one life cycle action, a plurality of life cycle actions to execute concurrently.

2. The method of claim 1 , wherein each of the one or more prerequisite services is identified based, at least in part, on one of a specific version number and a range of compatible version numbers.

3. The method of claim 1 , wherein the requirements of the service include propagating a configured parameter to a specific prerequisite service of the one or more prerequisite services.

4. The method of claim 3 , further comprising:
responsive to determining, by one or more computer processors, that the specific prerequisite service is unable to accept the configured parameter, sending, by one or more computer processors, an error message to a client.

5. The method of claim 3 , wherein the configured parameter is a parameter that corresponds to a user-configurable setting of the specific prerequisite service.

6. The method of claim 1 , further comprising:
responsive to determining, by one or more computer processors, that one or more life cycle actions of a specific prerequisite service of the one or more prerequisite services are not in a predefined order, sending, by one or more computer processors, an error message to a client.

7. The method of claim 1 , wherein the one or more prerequisite services include one or more infrastructure services.

8. The method of claim 1 , wherein the one or more prerequisite services include one or more middleware services.

9. The method of claim 1 , wherein the one or more life cycle actions are interwoven such that one or more life cycle actions of the service are executed before all of the one or more life cycle actions of each of the one or more prerequisite services are complete.

10. A method comprising:
receiving, by one or more computer processors, a request to deploy a service in a cloud computing environment;
querying, by one or more computer processors, a service repository for data that describes one or more requirements of the service;
identifying, by one or more computer processors, one or more prerequisite services based, at least in part, on the requirements of the service; and
dynamically generating, by one or more computer processors, a solution stack model from (i) a stack service model of the service and (ii) the one or more prerequisite services, wherein the solution stack model is based, at least in part, on the requirements of the service and wherein the service and the one or more prerequisite services execute concurrently via the cloud computing environment in accordance with the requirements of the service, and wherein dynamically generating a solution stack model comprises:
interweaving, by one or more computer processors, one or more life cycle actions of the one or more prerequisite services with one or more life cycle actions of the service based, at least in part, on a plurality of life cycle ordering rules, wherein (i) for each of the one or more prerequisite services and the service, the one or more life cycle actions are sequential, (ii) each life cycle action is associated with a respective indicator of a plurality of indicators, (iii) the plurality of indicators are represented as a sequential list of indicators, and (iv) the plurality of life cycle ordering rules comprise:
a first life cycle ordering rule that causes each life cycle action that is associated with a first indicator of the plurality of indicators to be skipped;
a second life cycle ordering rule that causes, for each indicator of the plurality of indicators that (i) is not the first indicator and (ii) is associated with more than one life cycle action, a plurality of life cycle actions to execute concurrently; and
a third life cycle ordering rule that causes one or more life cycle actions that are associated with a second indicator of the plurality of indicators to execute prior to one or more life cycle actions that are associated with a third indicator of the plurality of indicators, wherein the second indicator is listed before the third indicator in the sequential list of indicators.

11. The method of claim 10 , wherein each of the one or more prerequisite services is identified based, at least in part, on one of a specific version number and a range of compatible version numbers.

12. The method of claim 10 , wherein the requirements of the service include propagating a configured parameter to a specific prerequisite service of the one or more prerequisite services.

13. The method of claim 12 , wherein the configured parameter is a parameter that corresponds to a user-configurable setting of the specific prerequisite service.

14. The method of claim 12 , further comprising:
responsive to determining, by one or more computer processors, that the specific prerequisite service is unable to accept the configured parameter, sending, by one or more computer processors, an error message to a client.

15. The method of claim 10 , further comprising:
responsive to determining, by one or more computer processors, that one or more life cycle actions of a specific prerequisite service of the one or more prerequisite services are not in a predefined order, sending, by one or more computer processors, an error message to a client.

16. The method of claim 10 , wherein the one or more prerequisite services include one or more infrastructure services.

17. The method of claim 10 , wherein the one or more prerequisite services include one or more middleware services.

18. The method of claim 10 , wherein the one or more life cycle actions are interwoven such that one or more life cycle actions of the service are executed before all of the one or more life cycle actions of each of the one or more prerequisite services are complete.
