一個“緣”字，萬種風情——初識SO

 

今天終於見到了SO的廬山真面

 

想起一首詩

 

《題西林壁》

 

【宋】 蘇軾

 

橫看成嶺側成峯 遠近高低各不同

不識廬山真面目 只緣身在此山中

 

喜歡詩中闡釋的哲理，恰當得表達了我此時對宏偉的SOA的迷茫；

 

更喜歡其中的“緣”字

 

一個“緣”字，萬種風情啊

 

Wiki裏的SOA

 

    In computing, a service-oriented architecture (SOA) is a flexible set of design principles used during the phases of systems development and integration. A deployed SOA-based architecture will provide a loosely-integrated suite of services that can be used within multiple business domains.

 

    SOA also generally provides a way for consumers of services, such as web-based applications, to be aware of available SOA-based services. For example, several disparate departments within a company may develop and deploy SOA services in different implementation languages; their respective clients will benefit from a well understood, well defined interface to access them. XML is commonly used for interfacing with SOA services, though this is not required.

   

    SOA defines how to integrate widely disparate applications for a world that is Web based and uses multiple implementation platforms. Rather than defining an API, SOA defines the interface in terms of protocols and functionality. An endpoint is the entry point for such an SOA implementation.

   

    Service-orientation requires loose coupling of services with operating systems, and other technologies that underlie applications. SOA separates functions into distinct units, or services, which developers make accessible over a network in order to allow users to combine and reuse them in the production of applications. These services and their corresponding consumers communicate with each other by passing data in a well-defined, shared format, or by coordinating an activity between two or more services.

 

    One can envisage SOA as a sort of continuum, as opposed to distributed computing or modular programming.

 

想到哪裏，寫道哪裏

 

難免又想起了她，和她喜歡的“人生若只如初見”

 

 回到正題

 

把service進行邏輯上的組合，正是我今天見到的東西

 

這種經過邏輯組合的service集合，就是——SOA實現的中間件

 

頭腦中，突然閃過這樣的概念，

 

沒有經過求證，沒有經過仔細的思考

 

這就作爲我第一次給SOA實現的中間件，下個定義吧

 

Re-Search的精神，告訴我不斷的完善這個定義

 

那我就每天都給我所認知的SOA實現的中間件下一個定義吧

 

不斷的解釋它的本質，不斷的Deepen My Insight.

 

樂此不疲……

木蘭詞

作者: 納蘭性德

　　擬古決絕詞諫友。

　　人生若只如初見，何事秋風悲畫扇。等閒變卻故人心，卻道故人心易變。
　　驪山語罷清宵半，淚雨霖鈴終不怨。何如薄倖錦衣郎，比翼連枝當日願。
　

　　【賞析】
　　無疑，該闕詞章與白氏《長恨歌》皆涉及唐玄宗和楊玉環那段譭譽參半的愛情故事。
　　站在政治的角度，李隆基荒淫廢國。
　　從感情的意義上來看，雖然唐玄宗迫於三軍衆怒，無奈將楊貴妃賜死馬嵬坡，從此生死訣別、陰陽永隔，唐玄宗卻始終信守當初七夕夜半“在天願作比翼鳥，在地願爲連理枝”的誓言，縱“天長地久有時盡”，“此恨綿綿無絕期”，這種用情深遠的愛情故事，試問誰人不動容？
　　當然，我們已無法考證這段真摯愛情故事是否屬實，權且和納蘭一樣，首先肯定這段風流佳話。
　
　　納蘭此詞以一失戀女子的口吻譴責負心的錦衣郎。
　　起句非常新奇，本來兩情相悅，恨不能朝朝暮暮，然而如若知道遲早分離，倒不如保持“初見”時那種若即若離的美好。
　　然後描繪變心的人往往指責滿懷癡情卻無端被棄的一方首先變心，失戀女子的愛恨情殤可見一斑。
　　最後引用七夕長生殿的典故，譴責薄情郎雖然當日也曾訂下海誓山盟，如今卻背情棄義！
