Abstract

Various embodiments provide an assessment tool that enables an automated functional assessment of applications for migration to target cloud computing platforms, such as a Platform as a Service (PaaS). The technical capabilities of various types of applications in a traditional non-platform deployment are studied and support for these technical capabilities is evaluated relative to the target platform.

Claims

1. A computer-implemented method comprising:

receiving, with an automated migration assessment tool, code associated with an application that is to be migrated to a target cloud computing platform;

analyzing, using the automated migration assessment tool, the code to assess dependence of the code on technical utility services and capabilities; and

evaluating, using the automated migration assessment tool, support for dependent technical utility services and capabilities in the target cloud computing platform.

2. The method of claim 1, wherein the target cloud computing platform comprises a Platform as a Service (PaaS) platform.

3. The method of claim 1, wherein the code comprises Java byte-code and configuration and environmental parameter file.

4. The method of claim 1, wherein said analyzing comprises producing one or more patterns present in the code;

and mapping the one or more patterns to a list that describes the technical utility services and capabilities.

5. The method of claim 4, wherein said code comprises one or more .jar files.

6. The method of claim 1, wherein said evaluating is performed by mapping patterns extracted from the code to elements on a list that contains information about the level of support for dependent technical utility services and capabilities.

7. The method of claim 1 further comprising producing a report that describes support, in the target cloud computing platform, for the dependent technical utility services and capabilities.

8. The method of claim 7, wherein the report includes migration suitability indicators and recommendations to allow an evaluation of migrating the application to the target cloud computing platform.

9. One or more computer readable storage media embodying computer readable instructions which, when executed, implement a system comprising:

an automated migration assessment tool configured to allow migration assessment of code that is to be migrated to a Platform as a Service (PaaS) platform, the migration assessment tool comprising;

an analysis engine configured to assess code dependence on technical utility services and capabilities and produce dependency information;

a rule engine configured to attempt to match patterns in a list of technical utility services and capabilities with information appearing in the dependency information effective to produce a subset of patterns that are present in the code;

a migration evaluation engine configured to map the subset of patterns present in the code to a list of technical services supported by the PaaS platform effective to produce a migration list; and

,

a report engine configured to process the migration list to create a report that describes support, in the PaaS platform, for the subset of patterns present in the code.

10. The one or more computer readable storage media of claim 9, wherein the analysis engine is configured to assess .jar file dependencies.

11. The one or more computer readable storage media of claim 9, wherein the migration assessment tool is configured to provide the report as an HTML report.

12. The one or more computer readable storage media of claim 9, wherein the migration assessment tool is configured to provide the report as a PDF report.

13. The one or more computer readable storage media of claim 9, wherein the report includes migration suitability indicators and recommendations to allow an evaluation of migrating the code to the PaaS platform.

14. The one or more computer readable storage media of claim 9, wherein the migration assessment tool includes a user interface comprising a user interface instrumentality configured to allow a user to select files that are to be analyzed by the analysis engine.

15. The one or more computer readable storage media of claim 14, wherein the files comprise .jar files.

16. The one or more computer readable storage media of claim 9, wherein the report engine is configured to produce a report that allows comparison between multiple PaaS platforms.

17. A computing device comprising:

one or more processors;

one or more computer readable storage media embodying computer readable instructions which, when executed by the one or more processors, implement a system comprising;

a migration assessment tool configured to allow migration assessment of code that is to be migrated to a Platform as a Service (PaaS) platform, the migration assessment tool being configured to;

analyze the code and produce an XML file that describes the code'"'"'s dependencies on technical utility services and capabilities;

attempt to match patterns in a hierarchical list of technical utility services and capabilities with dependencies described in the XML file and produce an XML list that describes a subset of patterns present in the code;

process the XML list to map the subset of patterns present in the code to a hierarchical list of technical services supported by the PaaS platform effective to produce a migration list; and

create a report that describes support, in the PaaS platform, for the subset of patterns present in the code.

18. The computing device of claim 17, wherein the report is configured to provide a support status in the form of a visual icon to convey a level of support provided by the PaaS platform.

19. The computing device of claim 18, wherein the visual icon can assume different colors depending on the level of support.

20. The computing device of claim 17, wherein the report is configured to provide information about how the code should be changed in order to be migrated to the PaaS platform.
