雲計算與眾不同的三大原因

I assert that real cloud computing is not just a way of doing computing, but a way of thinking about computing that's diff erent from traditional approaches, specifically in terms of sharing, trusting, and accounting.

譯文：我總是驚訝于人們對雲計算的不同需求。 一部分人出於謀利動機，如那些雲計算的技術供應商。 還有一部分人會傾向于吹噓自家雲計算專案的能力，比如IT企業。 然而，在許多情況下，改變的只有標籤並無其它。 我主張，真正的雲計算不僅僅是一種計算方法，而是一種不同于傳統計算的思維方式，特別是在共用、信任和計算方面。

原文：The fundamental tenet of cloud computing is that we share resources, including storage, processing, and development too ls. Thus, the model is not just virtualization or remote hosting, it's the ability to manage thousands of tenants simultaneous ly in the same physical hardware environment. The obvious benefit of this aspect of cloud computing is the economy of scale and, thus, much lower operational costs.

譯文：雲計算的基本原則是資源分享，包括存儲、處理和開發工具。 因此，此模式不僅能虛擬或遠端託管，還能在同一物理硬體環境中管理成千上萬的資源。 雲計算這一方面最大的好處就是規模小，運營成本低。

原文：The second important aspect of cloud computing is the ability to trust those who manage your IT assets hosted on local or remote cloud computing platforms. The biggest barrier to cloud computing is not the ability to perform to SLAs, but for enterprises to trust public cloud pr oviders or those charged with private clouds with the management of those assets: no trust, no migration, no cloud.

譯文：雲計算第二點重要方面則是可以在本地或遠端雲計算平臺託管IT資產。 雲計算最大的障礙不是沒有能力運行SLAs，而是能讓企業委託公共雲的供應商或是私有雲的負責人管理資源：沒有信任，就沒有資料移轉，就沒有雲。。

原文：Finally, "accounting" refers to the ability to pay only for resources you use and to ensure you've been able to meet al l performance and uptime expectations. After all, you now get computing resources that show up like items in a phone bill, listing the time or the instances you accessed during a given period. Although many embrace this approach, others find it odd compared to current practices. In essence, it's a more sophisticated return to the timeshare model.

譯文：最後，「計算」指的是支付使用資源的能力及確保滿足所有性能和正常執行時間的能力。 畢竟，你得到了一些計算資源，如電話帳單上顯示特定時間內的電話記錄的條目。 雖然許多人接受這種方法，但有些人覺得與通用法相比，這種方法會有些古怪。 實質上這比分時模式更加精密。

原文：Cloud computing will become a reality only if we're able to think differently. If instead we try to fit our square pegs into a round hole by making a square hole, nothing changes. No value will come.

譯文：只有當我們以不同的方式思考問題，雲計算才能成為現實。 相反，如果我們方枘圓鑿，那麼將原地踏步，一無所獲。
