Abstract

Enabling migration of code in a service oriented architecture executed in a distributed computing environment. A migration definition for generating migrations is received, the migration definition exposing a tangible set of matchers and filters configured to locate code constructs and codebase settings of the code to be migrated. The code to be migrated is user defined. A deterministic script is scaffolded from the tangible set of matchers and filters to find instances of code to update or settings to update within the distributed environment. The instances of the code settings are updated, whereby the code in the service oriented architecture is migrated.

First claim

What is claimed is:

1. A method comprising:
migrating executable program code in a service oriented architecture executed in a distributed computing environment by a processor comprising:
receiving a migration definition for generating migrations, the migration definition exposing a tangible set of matchers and filters configured to locate code constructs and codebase settings of the executable code to be migrated, wherein the executable program code to be migrated is defined by a user;
scaffolding a deterministic script from a template based on the tangible set of matchers and filters to find instances of code to update or settings to update within the distributed computing environment; and
updating the instances of code or updating the settings, wherein updating is performed by using a parsed or tokenized code tree traversal and stateful data migrations to migrate code to be migrated, wherein updating consumes updates maintained in a centralized repository; and independently tracks its own upgraded state,

wherein stateful data migrations include a toolchain.

2. The method of claim 1 , wherein the migration definition exposes an application programming interface which is used to define migration of the executable code.

3. The method of claim 1 , further comprising the processor:
receiving input via the application programming interface, the input commanding the processor to revert the executable code to a previous state.

4. The method of claim 1 further comprising the processor:
receiving input via the application programming interface, the input commanding the processor to advance the executable code to a new state.

5. The method of claim 3 , further comprising the processor:
maintaining a state of to where a consuming code base has migrated at each point in time.

6. The method of claim 1 , wherein the deterministic script is scaffolded based on a user's consumption of an application programming interface and definition of the tangible set of matchers and filters.

7. The method of claim h further comprising the processor:
maintaining a state of to where a consuming code base has migrated at each point in time.

8. A computer program product, comprising:
a computer-readable storage media comprising instructions which, when executed by a processor, migrates code in a service oriented architecture executed in a distributed computing environment, wherein the code in the service oriented architecture comprises executable program code to be migrated, the instructions comprising:
first program code for receiving a migration definition for generating migrations, the migration definition exposing a tangible set of matchers and filters configured to locate code constructs and codebase settings of the code to be migrated, wherein the executable program code to be migrated is defined by a user;
second program code for scaffolding a deterministic script from a template based on the tangible set of matchers and filters to find instances of code to update or settings to update within the distributed computing environment; and

third program code for updating the instances of code or updating the settings, wherein updating is performed by using a parsed or tokenized code tree traversal and stateful data migrations to migrate code to be migrated, wherein updating consumes updates maintained in a centralized repository and independently tracks its own upgraded state
wherein stateful data migrations include a toolchain.

9. The computer program product of claim 8 , wherein the migration definition is configured to expose an application programming interface which is used to define migration of the code.

10. The computer program product of claim 8 , wherein the instructions further comprise:
fourth program code for receiving input via an application programming interface, the input configured to command the processor to revert the code to a previous state.

11. The computer program product of claim 8 , wherein the instructions further comprise:
fourth program code for receiving input via an application programming interface, the input configured to command the processor to advance the code to a new state.

12. The computer program product of claim 10 , wherein the instructions further comprise:
fourth program code for maintaining a state of to where a consuming code base has migrated at each point in time.

13. The computer program product of claim 8 , wherein the deterministic script is scaffolded based on a user's consumption of an application programming interface and definition of the tangible set of matchers and filters.

14. The computer program product of claim 8 , wherein the instructions further comprise:
fourth program code for maintaining a state of to where a consuming code base has migrated at each point in time.

15. A computing device comprising:
a processor; and
a computer-readable storage media comprising instructions which, when executed by the processor, migrates code in a service oriented architecture executed in a distributed computing environment, wherein the code in the service oriented architecture includes executable program code to be migrated, the instructions comprising:
first program code for receiving a migration definition for generating migrations, the migration definition exposing a tangible set of matchers and filters configured to locate code constructs and codebase settings of the code to be migrated, wherein the executable program code to be migrated is user defined;
second program code for scaffolding a deterministic script from a template based on the tangible set of matchers and filters to find instances of code to update or settings to update within the distributed computing environment; and
third program code for updating the instances of code or updating the settings, wherein updating is performed by using a parsed or tokenized code tree traversal and stateful data migrations to migrate code to be migrated, wherein updating consumes updates maintained in a centralized repository and independently tracks its own upgraded state

wherein stateful data migrations include a toolchain.

16. The computing device of claim 15 , wherein the instructions further comprise:
fourth program code for receiving input via an application programming interface, the input commanding the processor to revert the code to a previous state.

17. The computing device of claim 15 , wherein the instructions further comprise:
fourth program code for receiving input via an application programming interface, the input commanding the processor to advance the code to a new state.

18. The computing device of claim 16 , wherein the instructions further comprise:
fifth program code for maintaining a state of to where a consuming code base has migrated at each point in time.

19. The computing device of claim 15 , wherein the deterministic script is scaffolded based on a user's consumption of an application programming interface and definition of the tangible set of matchers and filters.

20. The computing device of claim 15 , wherein the instructions further comprise:
fourth program code for maintaining a state of to where a consuming code base has migrated at each point in time.

21. The computing device of claim 15 , wherein the migration definition is configured to expose an application programming interface which is used to define migration of the code.
