Gartner觀點突變 ：主張優先嘗試公共雲

&HTTP://www.aliyun.com/zixun/aggregation/37954.html">nbsp;當今社會，分析家的報告主導著IT業的策略，因此， 我花費了大量的時間解釋調研報告對於特殊企業和雲計算領域來說實際上意味著什麼。 很多時候，我會出於使用者的利益反對和打擊那些報告提到的建議。 當然，會出現許多反對我觀點的情況。 直至今天，鬥爭仍未結束。

不過，當分析家提出正確意見的時候，我也會大聲指出來。 這次，Gartner的 Daryl Plummer的言論是正確的，他在Gartner最近的IT討論會上給出意見：「只有當公共雲不能滿足企業需要的時候才能考慮私有雲，否則企業要優先考慮公共雲。 」

我們把現有系統移入雲計算或是創建新系統之前，應首先考慮使用雲計算的需求和目標，這就是此意見的核心。 不要只因私有雲解決了IT業忽視的問題就考慮私有雲；相反，要先尋找公共雲計算的價值。 如果公共雲不是最佳之選，再選擇私有雲。 但在任何情況下，要跟從企業的需求，而不是跟從天花亂墜的宣傳報導。

雖然這是我提出了多年的觀點，但現在Gartner說出了同樣的觀點顯然是一件好事。 （Gartner不經常分享這種主張。 ）許多企業支援私有雲，忽略公共雲的作用，他們通常會給公共雲貼上「過於危險」或是「不可操控」的標籤。

然而，雲計算的主要價值來自對公共雲的使用，其主要原因是使用者不必購買和維護自己的硬體和軟體。 但這的確需要你相信其他人能處理你的基礎設施、應用程式和發展需要。 這還意味著你要關閉一兩個資料中心並且減少領域範圍。 IT業中許多人難以處理這方面的問題；每次被問到雲計算時，他們都會選擇私有雲。

也許IT業會因為Gartner的報告優先考慮私有雲而言聽計從。

 Gartner and I finally agree -- now maybe IT will come to grips with the public cloud





I'm pretty vocal when analyst organizations provide hyped-up advice, replete with grandiose claims around the movement to some technology. The advice is both hard to follow by enterprises and many times just plain wrong -- which is why I usually loudly criticiz e it.





However, we still live in a world where analyst reports drive much of IT policy, so I spend a bunch of my time expla ining what the information actually means for a specific enterprise or problem domain. Many times, I disagree and push back on that advice for the good of the user. Of course, there are many instances where people don't concur about my opinion. The fight continues to this day.





However, when the analysts get it right, I loudly point that out as well. This time the "right call" was the assertion from Gartner's Daryl Plummer that "enterprises should consider public cloud s ervices first and turn to private clouds only if the public cloud fails to meet their needs." He delivered this advice during Gartner's recent IT Symposium.





At the core of this advice was the fact you should first consider your requirements and the objectives for using clo ud computing before you move existing systems to the clouds or create new systems. Don't jump right to private clouds just because they solve the problem that IT has with letting go; instead, look to the value of public cloud computing first. If it's not a fit, then go private. But in all cases, let the business requirements drive you, not the hype.





Although this is advice I've been providing for years, it's obviously a good thing that Gartner now says the same thing. (It didn't always share this opinion.) Too many enterprises jump right to private clouds and don't consider the use of public clouds, typically labeling them as too insecure and not controllable.





However, the primary value of the cloud comes from the use of public clouds, mainly because you don't have to purcha se and maintain your own hardware and software. But this does require that you trust somebody else to deal with your infrastructure, applications, and development require ments. It might also mean you shut down a data center or two and reduce the size of your kingdom. Many in IT seem to have a real problem with doing that; when asked to move to the cloud, they choose the private option each and every time.





Perhaps now that Gartner says the private cloud should be your first option, maybe IT will finally listen.
