雲端開發平台之建置經常需要花費大量的時間安裝與設定環境，不難想像，當雲端服務系統需要更新或者遷移時所需付出的成本將隨著系統擴增而急速上升。因此，我們希望藉由將預先安裝好的R語言程式開發平台包裝成Turnkey的型式，用戶只需要簡易安裝Turnkey的執行環境－Docker，並將Turnkey掛載於其上，便能快速建置與部署雲端服務平台，如此不論用戶想要更新或者遷移整個雲端平台，只需要將更新後的Turnkey重新掛載或者遷移至新的雲端環境，不再需要重新安裝與設定所有機器，有效的減少雲端開發平台重新建置時所必須付出的龐大成本。
在雲端服務平台之中，運算資源也是不可或缺的存在，為了避免過剩的運算節點造成資源浪費，我們針對運算資源管理設計了一套動態調節(Dynamic Provisioning)機制，藉由在每個執行的運算單元中加入timeout機制，適時增加與刪減運算節點之數量，藉此減少資源浪費與不足的情形發生，達到有效使用雲端資源的目的。
除此之外，為了使開發平台服務更具可攜性(Portability)，不論是整合式開發環境-Rstudio，或者是應用程式之上傳與部署介面，我們皆採取網頁形式呈現，用戶只需透過瀏覽器即可在個人電腦、行動裝置等多種前端平台上開發個人的策略腳本，不再受限於硬體設備與作業系統，有效的提高整體系統的可攜性。

Cloud development platform development with traditional virtual machine has always been too complex, too expensive, and too slow, therefore we hope to reduce costs by replacing traditional virtual machine with docker container. We build the cloud development platform which can run R language program on the docker container and make it to a turnkey. The user can update, migrate and run the turnkey quickly without reinstalling or resetting the host. It will reduce the cost of re-building the cloud development platform effectively.
In the cloud service platform, the computing resources are very precious. We design a dynamic provisioning mechanism for them so as to avoid redundant compute nodes. We adjust the number of compute nodes by timeout mechanism. When the running job is timeout, it means the system is too busy, and then we need to provide more compute nodes. When the utilization of compute nodes are too low, we will remove some compute nodes to reduce waste of resources.
In order to make our platform services have more portability, we implement our platform service on the web server. The users can using the platform service including the IDE (Rstudio) and the function of deployment on the PC, netbook or any mobile device (e.g. smart phone, tablet PC). The user will not be limited by hardware device and it will incresase the portability of system effectively.
