使用 Graviton Porting Advisor 來遷移到 AWS Graviton

可以分析源代碼並檢查在遷移到 AWS Graviton 時需要更改的過時運行library

優化 aws 成本的方法之一是遷移到並採用具有高性價比的AWS Graviton

推薦使用AWS Graviton，從可持續性的角度來看，它有很好的表現

但有需要注意的地方：

• 不適用於所有操作系統和實例類型
• 由於處理器設計和正在運行的應用程序規範，可能無法實現預期性能

特別是有這兩點高度依賴於正在執行的應用程序的要求而不是基礎設施，因此建議在遷移之前進行驗證

因此，在 GitHub 上發布了遷移指南

https://github.com/aws/aws-graviton-getting-started

https://github.com/aws/aws-graviton-getting-started/blob/main/transition-guide.md

在上面的文章中，介紹了Graviton 的 Porting Advisor 作為一種工具來幫助分析和更改工作負載中的軟體

嘗試使用

https://github.com/aws/porting-advisor-for-graviton

目前要分析的語言和檢查對像如下

• Python 3+
• • Python version
  • PIP version
  • Dependency versions in requirements.txt file
• Java 8+
• • Java version
  • Dependency versions in pom.xml file
  • JAR scanning for native method calls (requires JAVA to be installed)
• Go 1.11+
• • Go version
  • Dependency versions on go.mod file
• C, C++, Fortran
• • Inline assembly with no corresponding aarch64 inline assembly.
  • Assembly source files with no corresponding aarch64 assembly source files.
  • Missing aarch64 architecture detection in autoconf config.guess scripts.
  • Linking against libraries that are not available on the aarch64 architecture.
  • Use of architecture specific intrinsic.
  • Preprocessor errors that trigger when compiling on aarch64.
  • Use of old Visual C++ runtime (Windows specific).
  • The following types of issues are detected, but not reported by default:
  • • Compiler specific code guarded by compiler specific pre-defined macros.
  • The following types of cross-compile specific issues are detected, but not reported by default.
  • • Architecture detection that depends on the host rather than the target.
    • Use of build artifacts in the build process.

先決條件

• Python 3.10 or above (with PIP3 and venv module installed).
• (Optionally) Open JDK 17 (or above) and Maven 3.5 (or above) if you want to scan JAR files for native methods.

確認版本

#  python3 --version
Python 3.10.6
