Node.js ABC’s - M is for Modules

As any one who has created a software system can tell you, after some point you get to a point in time where putting all your code in one big location becomes unmanageable and leads to maintenance issues.  The logical first step is to try to separate code that is related into smaller distinct entities and "include" them in the project in question.  But, what happens if two...

This blog is adapted from the original post here.  企業組織採納雲端技術可以帶來許多不可否認的效益,包括成本節省、商務敏捷性、以及讓使用多種運算裝置的員工們達到更好的生產力。根據IDC所做的第五個年度終端使用者調查,亞太區資訊長(CIO)在2013年增加50%的雲端服務與技術支出,達到75億美元。再者,他們對於要使用何種類型的雲端模式以及要在雲端之上執行何種工作負荷,也都有必較特定的選擇。IDC在最近的Vendor Spotlight報告中指出,此一轉移趨勢提高了複雜化的層級,特別是在應用管理方面,包括應用該駐留在什麼地方以及管理人員是否有能力可以確保維護適當的安全性和網路成長。 儘管有著那麼多正面效益,但關鍵在於有一項致命且牽動所有層面的負面因素,阻礙企業朝雲端轉移 -...
