透過逆向工程解耦開源軟體中的雲端服務相依性：以 ClusterFuzz 為例

Abstract

在軟體開發的過程中，我們常常需要使用開源軟體來協助開發工作。然而，部分開源軟體雖然可以在本地端執行，卻與特定的雲端服務有相依性，這使得我們無法正常使用該軟體，或只能使用部分功能。因此，我們希望能找到一套逆向工程的流程和方法，解除開源軟體與雲端服務之間的相依性問題，同時找到替代方案以實現本地化。 本研究以Google開發的ClusterFuzz為案例，探討其與雲端服務之間的相依性。我們將解除相依性並尋找替代方案，接著進行驗證，最後使用Docker將ClusterFuzz部署到我們的伺服器上。 透過這套系統化的流程，我們成功地實現了ClusterFuzz的本地化，使其能夠在本地環境下完整且獨立地運行。

In the software development process, the utilization of open-source software is often crucial for facilitating the development workflow. However, certain open source software, despite being capable of local execution, may have dependencies on specific cloud services. Consequently, this hinders the proper utilization of the software or limits access to its functionalities. Therefore, it becomes imperative to establish a systematic reverse engineering process and methodology to decouple the dependencies to cloud services, while simultaneously seeking alternative solutions to achieve localization. This research focuses on ClusterFuzz, a software developed by Google, as a case study to identify its dependencies to cloud services. Our objective is to decouple these dependencies and find suitable alternatives to replace them. Subsequently, we proceed with validation and deploy ClusterFuzz on our server using Docker. Through this systematic process, we successfully achieve the localization of Clus terFuzz, enabling its complete and independent operation in a local environment.
