當前的幾種開源游戲服務端介紹
pomelo
Pomelo 是基於 Node.js 的高性能、分布式游戲服務器框架。它包括基礎的開發框架和相關的擴展組件（庫和工具包），可以幫助你省去游戲開發枯燥中的重復勞動和底層邏輯的開發。Pomelo 不但適用於游戲服務器開發， 也可用於開發高實時 Web 應用，它的分布式架構可以使 Pomelo 比普通的實時 Web 框架擴展性更好。

kbengine
一款開源的游戲服務端引擎，使用簡單的約定協議就能夠使客戶端與服務端進行交互，使用KBEngine插件能夠快速與(Unity3D, OGRE, Cocos2d, HTML5, 等等)技術結合形成一個完整的客戶端。
服務端底層框架使用c++編寫，游戲邏輯層使用Python(支持熱更新)，開發者無需重復的實現一些游戲服務端通用的底層技術，將精力真正集中到游戲開發層面上來，快速的打造各種網絡游戲。
(經常被問到承載上限，kbengine底層架構被設計為多進程分布式動態負載均衡方案，理論上只需要不斷擴展硬件就能夠不斷增加承載上限，單台機器的承載上限取決於游戲邏輯本身的復雜度。)
