最近科技業各界紛紛把雲端這塊招牌掛在自己開發的技術上,彷彿必須通過業者所提供的平台才可觸碰到這塊雲。究竟雲端運算是什麼東西,且看本文分曉。

 

雲端是什麼碗糕

 

雲端運算(cloud computing)這東西很妙,你拉十個人來問可能會得到十一種答案。各行各業對它的解讀不盡相同,我看到最寬鬆的定義是「使用者可無腦的經由網路得到他們想要的服務」,我相信這種對於雲端的定義肯定也相當無腦。

 

較嚴謹的定義為「使用底層的分散式運算技術建構出上層可透過網路提供使用者自行達到快速部署及按使用量計費的服務方式」,唸完這句話也差不多該去喝個水透個氣了。雲端這種行話(buzz word)在此我也不想多作定義,免得擋人財路。

 

不過大家都有的雲端服務共識分為三個層次:基礎設施即服務(Infrastructure as a Service , IaaS)、平台即服務(Platform as a service , PaaS)和軟體即服務(Software as a Service , SaaS)。簡單來說就像經由網路這條通道分別提供使用者作業系統平台、API工具或是應用程式來使用的服務。

 

 

三種不同層次的雲端運算服務,以及它們分別的例子。

 

雲端怎麼這麼夯

 

最根本還是一句話:商機啊!雲端對企業最直接的效益便是節省建置軟硬體設備及維護所需的花費,並可依所需彈性調整運算資源,反正用多少付多少,多退少補嘛。其實大家已經用得很習慣的Google相關服務就屬於雲端應用,只是Google目前所提供的層級屬於PaaS和SaaS,你只能照它的遊戲規則來玩,其餘免談。

 

但身為進階級的玩家怎麼可以被框架給限制住呢?以雲端服務的三個層級來看,IaaS提供的彈性最大,業者你給我我想要的作業系統平台,剩下的我自己來搞。目前地球上規模最大的IaaS供應商,則莫過於Amazon Web Services(AWS)所提供的EC2(Elastic Compute Cloud)。大家對於Amazon肯定不陌生,Amazon.com為美國最大的一家網路電子商務公司,旗下最有名的就是亞馬遜網路書店。

 

 

Eucalyptus的三層架構:Cloud Controller、Cluster Controller和Node Controller。

在香港四季飯店泳池裡,聽到的不是自己的呼吸聲,而是莫札特樂曲。這是香港四季飯店特有的音樂泳池,泳客在池裡欣賞音樂,浮出水面,音樂就消失了。

 

富比世雜誌(Forbes)日前公布最新「全球最佳飯店」名單,香港四季飯店榮獲「全球最佳泳池」,得獎的原因除了池畔有絕佳的維多利亞港美景,潛入池水可聽到古典音樂,才是它獲獎的主因。

 

另一個台灣旅客熟知的飯店,是榮獲「最具歷史風情」的香港半島酒店。半島酒店只有八十一年歷史,但它英國殖民時期的建築風格、內部陳設與裝潢、甚至菸灰缸等小傢飾,都保存得相當完好,英式下午茶的傳統是該酒店的特色,充滿復古懷舊氣息。

 

這份全球最佳飯店區分十六個項目,「全球最奢華飯店」由拉斯維加斯WYNN飯店的高塔套房奪得,旅客一下飛機,就可在機場內專屬的招待所休息、接受最殷勤的服務;高塔套房很寬敞,號稱北美最大。住宿約一萬台幣起跳,淡季時最奢華的房型要價三萬三千台幣。

 

獲得「全球最佳酒吧」的是紐約St. Regis飯店,擁有古色古香的骨董吧台,據悉是「血腥瑪麗」調酒的發明地。新婚夫妻度蜜月,不妨考慮被評選為最浪漫的美國加州蘇路城堡(Chateau du Sureau),外觀就像城堡一般,房間裡的壁爐、燭台等,營造浪漫氣息,讓人捨不得離去。

 

至於榮獲「最佳飯店設備」的比佛利山莊Montage飯店,除了內裝讓評審印象很深刻,當旅客就寢時,會發現枕頭上竟然繡著自己名字的縮寫,真是讓人又驚又喜、感動入眠。

 

就連浴室也有獎項,榮獲「全球最佳浴室」的是拉斯維加斯米高梅Skylofts精品旅館,以寬敞舒適的浴室獲獎,浴池就像泳池一般,還有燈光紓壓、如香檳般冒著柔細泡泡的池水,配上池畔大螢幕電視。

 

紐約的川普國際酒店及中心榮獲「最佳景觀獎」,偌大落地窗正對中央公園,擁有絕佳的視野和景觀,尤其秋天楓紅時,最是美。

 

評審臥底 住飯店 打分數

 

富比世雜誌每年都會評選「全球最佳飯店」,評選對象是四星與五星飯店,為求公正,必須經過一次具名和兩次匿名的探訪考察,最後選出各個項目的得獎名單。

 

評審團會以具名方式進入飯店考察,考評項目有兩百多個欄目,在三天兩夜的考評期間,仔細針對飯店設施、床鋪是否舒適、裝潢是否華美、浴室是否清潔等逐項評審。

 

評審團另外安排兩次匿名考評,評審化身一般旅客投宿飯店,在無預警的情況下深入探訪。

 

為了讓評審更加公平、公正,評審團不接受任何招待,投宿飯店的費用皆由富比世雜誌負擔。

Dragon's Blood Trees, Socotra

To create our list of some of the world's most unique places to visit, we spoke with several travel experts, and asked them to recommend destinations based on their own past journeys. Those weighing in included Giampiero Ambrosi, general manager of Virtual Tourist; Pamela Bryan, co-founder of Manhattan Beach, Calif.-based travel firm Off the Beaten Path; Bruce Poon Tip, chief executive of Toronto-based travel company G.A.P. Adventures; and William Altaffer, owner and founder of Expedition Photo Travel in San Diego.

 

See the full list of the World's Most Unique Places To Visit


The Dragon's Blood Trees of Socotra

The otherworldly Dragon's Blood Trees and other 700 rare species of flora and fauna have drawn people to Socotra, an island in the Indian Ocean, off the horn of the African continent. Giampiero Ambrosi of Virtual Tourist says, "The trend of eco-tourism is especially strong here."


Takstang Monastery, Bhutan

Takstang Monastery in the Kingdom of Bhutan

The Kingdom of Bhutan is the last remaining kingdom in Asia and is the only place in the world to measure Gross National Happiness. Takstang means "tiger's lair" and hangs on a cliff high above the Paro valley. Visitors must climb the slope on foot or by mule.


Salt Plains, Salta, Argentina

The Salt Plains in the Salta, Argentina

Off the Beaten Path travel agency recommends the Northwestern Salta province of Argentina. The salt plains here are a pure white expanse, surrounded by high mountains. The Inca tribes that originally inhabited the area offer a unique cultural history.


Head-Smashed-In Buffalo Jump, Alberta, Canada

Head-Smashed-In Buffalo Jump, Alberta, Canada

For 5,500 years, the Native Americans of the North American Great Plains killed bison by chasing them off this cliff located in what's now Alberta, Canada. They would then carve up the bison carcasses in the camp below. This is one of the biggest and best preserved buffalo jumps in North America, according to Off the Beaten Path co-founder Pamela Bryan. It was named a UNESCO World Heritage Site in 1981.


Throat Singers of Tuva, Siberia

 

Throat Singers of Tuva, Siberia

The throat-singing Tuva people of southern Siberia create sounds and harmonies unique to foreigners' ears. It is a style that simultaneously combines two or more pitches over a fundamental pitch to create sounds mimicking nature. The pastime is popular especially among the Tuvan male herders, because they are able to practice in the broad, open fields while they work.

旅遊指南聖經「寂寞星球」3日公布「2010年全球最佳旅遊勝地」(Best In Travel 2010),遭金融風暴重創的冰島「塞翁失馬焉知非福」,不再貴不可攀,獲選為最超值旅遊地點。中美洲薩爾瓦多和阿拉伯聯合大公國首都阿布達比,分占最佳旅遊國家及城市之冠。

寂寞星球(Lonely Planet)表示,其所出版的全球旅遊勝地指南,搜羅「未來一年最夯旅遊潮流、地點、行程和經驗」。

冰島雖受金融風暴影響,經濟嚴重衰退,但相對地消費不若以往昂貴。冰島擁有豐富自然景觀,冰河、火山及夢幻的藍湖溫泉,寂寞星球推薦,2010年正是撿便宜前往冰島的好時機。

泰國和倫敦分列最超值旅遊地點的二、三名,寂寞星球說,泰國旅遊「一直都非常划算」,堅強實力令他國難以匹敵,尤其受歐洲客喜愛。倫敦一改過往昂貴印象,物價親民許多,加上英鎊貶值,平價旅館興起,餐廳亦降價吸引顧客。

各富文化或自然風情的國家及城市,亦被寂寞星球選為10大旅遊國家/城市,例如厄瓜多第三大城匡卡,位於海拔約2,500公尺的高原地區,其城區被聯合國教科文組織列為世界文化遺產。義大利南部城市雷契,充滿巴洛克風格古蹟;火山地形豐富,氣候宜人的薩爾瓦多,以及中東地區阿布達比等。
