李家同:原來,我早就在「雲端」
最近看到媒體大肆討論「雲端計算」,我這個土包子不知道何謂雲端科技,所以就查了一下雜誌,發現所謂雲端科技,無非就是將所有的資料都送到網路去處理。我鬆了一口氣,知道我不但不是土包子,而且是一個先知先覺者,因為在民國九十一年就已經將資料一概都儲存到位在遠處的電腦裡。
李家同教授關於「雲端運算」(Cloud Computing,我不喜歡這個譯名,但這是後話)的這篇文章,在網路上引起不少人的訕笑,不過我對他的說法倒是有幾分同意。
如果您曾經經歷「傻瓜終端機」的年代,就會知道那時候的電腦也都將資料送到遠端主機去計算、交換、儲存。純就概念來說,所謂雲端運算其實大致並不脫這個範圍。
然而,現在當然有很多新的東西是那時候沒有的,而新的技術、軟硬體、以及合作運算方式也確實需要有個名字來概括。20年前有終端機、遠端主機、網路的概念與實踐,但沒有今天「雲端」所不可或缺的普及Internet連線、行動運算、網頁技術等等,所以做不到現在的很多事情;然而就像「非洲賣鞋」的老笑話到「藍海」的新名詞一樣,「雲端」的東西可以做、該做,不過不必像發現新大陸一樣,光看到名稱就一頭熱。
很多人也許有資格笑李教授過氣,我自己也不盡然同意他的每一個看法;但有些事情如果曾經走過那一段,也許看法就會有所不同了。
Dr. Lee: Cloud Computing is not new.
In fact, I am kind of agreeing with Dr. Lee's view about Cloud Computing, since I've also been through the age that dumb terminals could do nothing but sending data to the mainframe for computation, exchange and archiving; the so called "Cloud" is conceptually not much more than that.
However indeed it calls for a new name and new concept to contain the new technology, hardware/software and collaboration methods. Some of the "Cloud" stuff were just unavailable 20 years ago, mainly the pervasive Internet, mobile computing and Web technology, but the idea was really not new.
Well, we can laugh at Dr. Lee and said he's a passé; but if you've been there, done that, you wouldn't wonder why he said that.
