資訊應用的發展從早期集中式處理主機終端機作業模式，轉變到折衷作業之主從架構，再演進至現在分散式處理之WEB環境，這些進步都拜資訊網路科技快速進步之賜，在雲端運算架構概念引進後，整合後端基礎建設與高速傳輸網路，將資訊運算與資料儲存朝後端集中運作將成為未來資訊發展的新主流。本局亦將以雲端運算架構為基礎規劃資訊作業的中長期展望，導入虛擬化技術與雲端儲存來建置資訊應用的新里程碑，以營造一個更適合本局同仁使用之友善資訊作業環境。 本文的目的在介紹本局資訊作業發展歷程，及目前整體資訊運作環境現況與推動方針，並探討資訊應用未來發展趨勢，最終擬定本局中長期資訊發展計劃。

Thanks to the rapid progress of information technology (IT), the development of information applications transformed from the use of a centralized terminal server in early times to client servers, and then further evolved into the current distributed computing web-based environment. Since the concept of cloud computing was introduced, the use of virtualization and cloud storage has become a mainstream of future IT development by integrating back-end infrastructure with high-speed transmission networks to make the best use of upgrades in personal computer power. Taipei City Department of Rapid Transit Systems (DORTS) also has a long-term plan for its IT operations based on a cloud computing framework to reach the goal of using virtualization technology and cloud storage and establish improved IT applications so as to create a more user-friendly IT work environment for DORTS staff members. This article focuses on describing the development of DORTS´ IT operations, overall IT operation environment status and implementation policies, a study of future development trends, and the drawing up of the long-term IT development plan.
