Abstract

Disclosed are embodiments of an adaptive enterprise service bus (ESB) runtime system and an associated method, which build, at a restart, only the most advantageous path configuration between composable units (e.g., between applications and/or between primitives within a single application). Specifically, during the execution of instantiations of modeled paths and branches thereof, metrics (e.g., the number of times each flow and each branch are activated, the CPU usage associated with building each flow and each branch, etc.) are collected. Then, at a restart of the runtime system, a cost-benefit analysis is performed on the collected metrics and, based on the results of this cost-benefit analysis, only selected ones of the paths and the branches thereof are built (e.g., paths and branches for which operational usefulness outweighs building costs). Other paths and branches are built only as required, during running of the runtime system.

Claims

1. An adaptive enterprise service bus (ESB) runtime system comprising:

a processor operable to receive a model for an enterprise system bus (ESB), said model comprising a plurality of paths between composable units with at least one of said paths comprising a plurality of branches and said processor being further operable to build instantiations of said paths and said branches; and

,

a server operable to execute, during each running of said runtime system, said instantiations of said paths and said branches built by said processor,

wherein said processor is further operable to build, at a restart of said runtime system and based on results of a cost-benefit analysis, instantiations of only selected ones of said paths and said branches,

wherein said cost-benefit analysis is performed, by an analyzer, using metrics for said paths and said branches, and

wherein said metrics are collected, by a monitor, during said executing of said instantiations by said server.

2. The system of claim 1, wherein, during an initial running of said runtime system, said processor only builds said paths and said branches, as required, on-demand.

3. The system of claim 1, wherein, at an initial start-up of said runtime system, said processor builds all of said paths and said branches.

4. The system of claim 1, wherein, at an initial start-up of said runtime system, said processor selects a portion of said paths and said branches, based on pre-loaded historical data and builds only said portion and wherein, during an initial running of said runtime system, said processor builds any additional portions of said paths and said branches, as required, on demand.

5. The system of claim 1, said processor further receives said model from an integration developer.

6. The system of claim 1, said metrics comprising a number of times each of said paths and each of said branches is activated, during each running of said runtime system, and at least one of an amount of computer processing unit usage associated with building each of said paths and each of said branches, an amount of time associated with building each of said paths and each of said branches and an actual cost associated with building each of said paths and each of said branches.

7. The system of claim 1, wherein all paths and branches built during a given running of said runtime system will remain built at least until said runtime system is restarted.

8. An adaptive enterprise service bus (ESB) runtime method, said method comprising:

receiving a model for an enterprise system bus (ESB), said model comprising a plurality of paths between composable units, at least one of said paths comprising a plurality of branches;

building instantiations of said paths and said branches; and

executing, during each running of a runtime system, built instantiations of said paths and said branches,

wherein said building further comprises, at a restart of said runtime system and based on results of a cost-benefit analysis, building instantiations of only selected ones of said paths and said branches, said cost-benefit analysis being performed based on metrics collected for said paths and said branches, during said executing.

9. The method of claim 8, said building further comprising, after said receiving of said model and during an initial running of said runtime system, building said paths and said branches only as required.

10. The method of claim 8, said building further comprising, after said receiving of said model and at an initial start-up of said runtime system, building all of said paths and said branches.

11. The method of claim 8, said building further comprising:

after said receiving of said model and based on pre-loaded historical data, selecting a portion of said paths and said branches;

at an initial start-up of said runtime system, building said portion; and

during an initial running of said runtime system, building any additional portions of said paths and said branches only as required.

12. The method of claim 8, said receiving of said model comprising receiving said model from an integration developer.

13. The method of claim 8, further comprising collecting of said metrics, wherein said collecting comprises determining a number of times each of said paths and each of said branches is activated, during each running of said runtime system, and further determining at least one of an amount of computer processing unit usage associated with building each of said paths and each of said branches, an amount of time associated with building each of said paths and each of said branches and an actual cost associated with building each of said paths and each of said branches.

14. The method of claim 8, wherein all paths and branches built during a given running of said runtime system will remain built at least until said runtime system is restarted.

15. A computer program product for an adaptive enterprise service bus (ESB) runtime method, said computer program product comprising a computer usable medium having computer usable program code embodied therewith, said computer usable program code being configured to perform a method, said method comprising:

receiving a model for an enterprise system bus (ESB), said model comprising a plurality of paths between composable units, at least one of said paths comprising a plurality of branches;
