傳統應用程式往往安裝於本地端電腦或是特定平台，在使用上會受限於個別環境，抑或需要為傳統應用程式安裝其他所需之工具。程式開發人員也需要隨著作業系統更新而需要開發更多版本應用程式，以及因應不同作業系統開發與維護應用程式。為了不受限於個別環境，可將桌面應用程式轉型網頁化，再將網頁應用程式轉型雲端化。網頁化為將原本運行在本地端電腦或特定平台上的應用程式轉化為能在網頁瀏覽器中提送需求並交給網頁伺服器運行的應用程式；雲端化是指將應用程式、資料、服務或基礎設施佈署和運行在雲端運算平台上的過程。而轉型雲端化可以透過容器化技術將應用程式封裝於容器中，並利用容器管理平台Kubernetes(K8s)實現容器應用程式的自動佈署、擴充和管理。
本研究的目標是建立傳統應用程式雲端轉型流程，將傳統應用程式雲端轉型流程分兩步，首先分析傳統應用程式轉型網頁流程，再來建立網頁應用程式轉型雲端流程。本研究以離散元素分析模擬視覺化展示系統為例，在分析傳統應用程式轉型網頁流程後，以該網頁系統實作網頁應用程式轉型雲端流程。
本研究所轉型雲端之實例提供利用容器可以配置資源之特性，透過上傳時配置離散元素分析模型計算所需之資源條件，在叢集中尋找符合條件之節點運行容器應用程式。另外，該實例提供多種錯誤提示，協助使用者調整檔案內容抑或是資源配置調整。最後，測試系統轉型雲端實例所提升之服務，並檢核轉型雲端實例較原應用程式提升之優點。系統服務測試展示轉型雲端後更動及新增之服務，講述網頁應用程式結合K8s資源物件配置之實作成果。轉型雲端提升之優點以隔離性和安全性、可擴展性、可管理性、持續可用性以及錯誤應對策略，說明驗證本研究系統關注之功能。

Traditional applications are often installed on local computers or specific platforms, which can limit their usage to individual environments or require the installation of additional tools. Programmers also need to develop multiple versions of applications as operating systems evolve and maintain them for different operating systems. To avoid limitations imposed by individual environments, desktop applications can be transformed into web applications and further transitioned into cloud-based solutions. Webification involves converting applications originally running on local computers or specific platforms into ones that can process requests in web browsers and run on web servers. Cloudification refers to the process of deploying and running applications, data, services, or infrastructure on cloud computing platforms. Transitioning to the cloud can be achieved through containerization, where applications are packaged into containers, and Kubernetes (K8s) is utilized as a container management platform to enable automated deployment, scaling, and management of containerized applications.
The objective of this research is to establish a cloud transformation process for traditional applications. This process consists of two steps: analyzing the transition of traditional applications to web-based platforms and then establishing a process for transitioning web applications to the cloud. Using a Discrete Element Analysis simulation visualization system as an example, this study first analyzes the process of transitioning traditional applications to web-based platforms and then implements the process of transitioning web applications to the cloud using the same system.
The cloud transformation example provided in this research leverages the configurability of containers. It allows users to upload configurations for resource conditions required for computing Discrete Element Analysis models and identifies nodes within the cluster that meet these conditions to run containerized applications. Additionally, the example provides various error prompts to assist users in adjusting file contents or resource configurations. Finally, the system's services post-cloud transformation are tested to demonstrate improvements and advantages over the original application. Service testing showcases modifications and additions made after transitioning to the cloud, emphasizing the implementation results of web applications combined with Kubernetes resource object configurations. The advantages of cloud transformation include isolation and security, scalability, manageability, continuous availability, and error handling strategies, illustrating the functionalities validated by this research system.
