Abstract

Techniques are described for a software modernization service to provide the ability to re-platform software application binaries from one ISA and hardware platform to another. The software modernization service can generate assessment reports for users' legacy applications, including recommendations for hardware platforms available in a cloud provider network for use. Responsive to a user requesting to re-platform an application from one ISA and hardware platform to another, an application re-platforming service automates steps to perform a static and dynamic binary translation of an application and to combine the results into a re-platformed executable. Among other benefits, the described techniques enable the deployment of legacy software applications onto a wider set of target ISA and hardware platforms, thereby enabling such applications to take advantage of the performance, scalability, availability, and other benefits of certain types of hardware platforms as desired by a user.

Claims20

Dependent claims

A computer-implemented method comprising:

receiving, by a software modernization service provided by a cloud provider network, a request to re-platform a software application from a first instruction set architecture (ISA) to a second ISA, wherein a first binary file used to execute the software application on computing hardware implementing the first ISA is stored in a computing environment that is distinct from the cloud provider network;
and
generating, at least in part by computing resources provisioned by the software modernization service, a second binary file to be used to execute the software application on second computing hardware implementing the second ISA by:
performing a static binary translation of instructions contained in the first binary file to obtain first binary translation results, wherein the static binary translation involves translating instructions contained in the first binary file to a language-independent intermediate representation,
performing a dynamic binary translation based on execution of the first binary file to obtain second binary translation results, wherein the dynamic binary translation involves translating instructions obtained from the first binary file during runtime to the language-independent intermediate representation,
determining a percentage of code contained in the first binary file covered by the dynamic binary translation relative to the static binary translation,
terminating the dynamic binary translation responsive to determining that the percentage of the code exceeds a threshold,
combining the first binary translation results and the second binary translation results to obtain combined translation results, and
using a compiler associated with the language-independent intermediate representation to compile the combined translation results into the second binary file.
