Slithice是做什麼的

Slithice 是一個跨平臺的分佈式架構框架；

旨在簡化分佈式開發的開發難度，節省開發成本和後期維護成本；

並提供穩定的分佈式容錯機制；

其界面化的集羣配置，一體式開發&分佈式發佈，插件覆蓋，容錯調度是 Slithice 最大的亮點；

Slithice 提供任意程序集，任意命名空間，任意類名的擴展，包括：

配置數據獲取方式的擴展（從什麼地方找尋服務器配置數據）；

調度方式的擴展（比如WCF，Socket，WebService等）；

功能插件的擴展（這個就是最重要的了）；

Ps. Slithice 並非只針對集羣服務器，同時 Slithice 也支持最簡單的一個服務端&多個客戶端的最簡分佈式；

Slithice名字的由來

Slithice 是 DotA 故事中，娜迦海妖的名字 —— 只是因爲半年前練習小娜迦，所以才選取了這個名字；

Slithice的版本演化

之前時間，Slithice 的架構設想閃現於腦海，於是整理了最簡單的設計手稿和實現目標

2013-02-10 Project版本庫正式動工取名 Slithice 2013 累計耗時20小時，完成先行版 Demo；

2013-06-10 Laura版本庫項目遷移維持原名累計耗時60小時，完成現在版本；

Slithice的目標

Slithice 的基本目標就是簡化集羣分佈式開發；

Slithice 的終極目標就是跨平臺：

服務端可以用 .Net、Java 等開發；

客戶端可以用 .Net-PC、.Net-WinCE、.Net-WinPhone、Java、Android、IPhone 等開發；

—— 想必，這是極好的；

順帶提一下 Slithice 的序列化

Slithice 支持 .Net 自帶的序列化（不能跨WinCE等平臺）和 Laura.Serialization 序列化 —— 沒有使用架構；

Laura.Serialization 是作者順手累計 30小時完成的一個序列化算法；

Laura.Serialization 支持 .Net-PC、.Net-WinCE 兩個平臺；

Laura.Serialization 序列化的 byte[] 結構分爲：類型區，數據區，結構區

Laura.Serialization 設計思想，只要對類型區進行控制：基本就能實現跨 Java，Android 等其他平臺；

Laura.Serialization 作者順手 5小時，寫了一個 Json 序列化算法（用字符串跨平臺顯得容易很多）

Slithice集羣配置工具主界面

在測試 Slithice 的 Demo 中，我配置了 7個服務端：

一個 WCF 的中央服務端；

兩個 WCF 的成員服務端（私有 – 前面有一個棕色皮包的圖標）；

兩個 Socket 的成員服務端；

兩個 WebService 的成員服務端；

Slithice集羣配置工具配置界面

我們看到的是 WebService_002 的配置

>藍色區域裏面的是當前服務端自己可以處理的 Action；

>紅色區域裏面的是當前服務端自己不能處理，但是可以調度出去的 Action；

>紫色區域裏面的是當前服務器可以調度的子服務器（就是兩個 WCF 服務）；

>按照 Slithice 的設計思想：能夠自己處理的任務，除了強制指定任務的服務器外，基本都會自己處理，自己處理不了的，纔會進行調度；

上面展示的是 WebService_002 可以調度出去的 Action；

>TestAction_001、TestAction_002 兩個子服務器都可以調度；

>TestAction_1_001、TestAction_1_002 只有 ConsoleWCFService_001 可以調度；

>這裏，做了一個 BUG配置：我們將 Slithice_ResetService（重置服務器）的功能沒有勾選爲自己處理，結果重置服務器的功能也將會被調度；（Slithice 內置的 Action插件並沒有特權）

>調度機率：在配置服務端時候，可以按照服務端所在的硬件設備的處理能力設置這個值，默認 100000；當對一個服務端的調度出現錯誤時，該值會 -1，調度成功時，該值會 +1 —— 調度機率，決定了同一個任務可以多個調度時的調度機率；

Slithice集羣配置工具插件覆蓋界面

上面展示的是插件覆蓋界面；

>ConsoleCenterService 具有幾個自定義Action；

>其中，TestAction_Center_001 有兩個版本，他們是同鍵值的，但是最終被啓用的是優先級更高的 100010；

>插件優先級的設置，爲了避免問題，可以使用 yyMMddHH 這種模式；

>Slithice 內置 Action 是沒有特權的：Slithice內置Action 也是可以被覆蓋的 —— 當然，還是有多少的特殊處理：

Slithice 內置 Action 優先級最大值可以是 Int64.MaxValue；

自定義 Action 優先級最大值可以是 Int32.MaxValue；

Slithice集羣配置工具單元測試界面

上面展示的是單元測試界面；

>因爲時間比較急，所以插件執行時需要的參數這個功能並沒有實現；

>因爲時間比較急，所以插件測試的是服務端本地固有Action 的測試，並不包括服務端可調度的 Action 測試；

>因爲時間比較急，所以性能壓力測試的功能並沒有實現；

Slithice 是開源的

Slithice 的作者是舒小龍；

Slithice 是開源的，任何企業或個人都可以無償用於商業或非商業用途；

當然，作者希望各位能在舒小龍的個人博客或者博客園回覆一哈：使用者名稱+軟件名稱+郵箱(可選)；

爲什麼要開源：

北京公司，在抽菸室和馬瑞禮（馬哥）聊天中，就聊到了這個話題，當時馬哥的回答讓自己有所頓悟：

今天自己的代碼比起幾年前成長了不少，當初的王牌代碼在今天也不過如此

—— 未來幾年後，今天的代碼或許在未來也只是 “不過如此”；

所在的角度和高度在提升，思想也就不一樣吧；

最最重要的是：王牌代碼給不了一個人未來，能成就一個人未來的是合作共贏的力量；

Ps. 感謝那段時間馬哥那次關於“開源”的討論，也感謝那段時間馬哥在人生道路上對我的各種指點，還有那次的寬容，收益很深；
