摘要

不同組織採用雲端服務所面臨的問題會依其採用服務種類以及使用方式有所不同。雲端運算服務所提供的資訊架構及流程相較於傳統資訊架構複雜許多，因此，採用雲端服務前需逐步對整體雲端服務採用進行全面性的評估，掌握各環節潛藏的風險，同時，對於潛在風險可能造成的衝擊，亦需與服務提供者事先明確地完成協議以降低帶來的傷害，才能享受雲端服務所帶來的效益。伴隨雲端運算的發展，組織內資訊系統隨著雲端特性的演進、技術發展的成熟、服務標準的建立已逐漸影響資源的整合與業務的發展。本研究以組織導入雲端運算的觀點提出一個系統雲端化的資訊治理架構，從需求、設計、到驗證的階段，分別提出具體的評估程序，歸納並推導嚴謹的系統雲端化的流程。此經過嚴謹設計的評估準則可做為未來企業導入雲端化的參考。

While moving to the cloud, organizations are facing different challenges depend on different service models and method selections. Cloud computing services usually bring a more complicated information architecture and process than usual. Therefore, it is necessary to have a comprehensive assessment of cloud computing strengths, weaknesses, benefits, risks, and impact before the actual cloud adoption. Apart from this, to reach an agreement and consensus with service providers in advance is also important, which is the key to rapid and effective success. This study proposes a method for system cloudified under IT Governance. For each phase of requirement analysis, design, and validation, it concludes criteria to guide companies to transfer systems in cloud computing. It will be a useful reference for private sectors that are willing to adopt cloud services.
