Accelerating application modernization

One or more non-transitory computer-readable storage media having program instructions stored thereon that, when read and executed by a processing system, direct the processing system to at least:

• record a run of existing code, wherein the existing code makes up at least a portion of an application and is written in a first programming language;
• generate a behavior model based on the recorded run, wherein generating the behavior model comprises:
• identifying and labeling one or more functional areas of the existing code;
• and
• identifying one or more code paths connecting steps performed by the existing code;
• generate an architecture depiction of the at least a portion of the application depicting one or more features of the application, wherein generating the architecture depiction comprises generating a high-level view of the existing code by rolling up the one or more code paths;
• generate new code based at least on the behavior model and a target environment, wherein the new code is written in a second code language that is distinct from the first programming language;
• deploy the new code in a target environment;
• and
• compare behavior of the new code to one or more of the existing code, predicted behaviors, and desired behaviors.

A computing apparatus comprising:

• one or more computer-readable storage media;
• a processing system operatively coupled with the one or more computer-readable storage media;
• and
• program instructions stored on the one or more computer-readable storage media that, when executed by the processing system, direct the processing system to at least:
• record a run of existing code, wherein the existing code makes up at least a portion of an application and is written in a first programming language;
• generate a behavior model based on the recorded run, wherein to generate the behavior model, the program instructions direct the processing system to:
• identify one or more functional areas of the existing code;
• and
• identify one or more code paths connecting steps performed by the existing code;
• generate an architecture depiction of the at least a portion of the application depicting one or more features of the application, wherein generating the architecture depiction comprises generating a high-level view of the existing code by rolling up the one or more code paths;
• generate new code based at least on the behavior model and a target programming language, wherein the target programming language is distinct from the first programming language;
• deploy the new code in a target environment;
• and
• compare behavior of the new code to one or more of the existing code, predicted behaviors, and desired behaviors.
