当前的几种开源游戏服务端介绍

pomelo

Pomelo 是基于 Node.js 的高性能、分布式游戏服务器框架。它包括基础的开发框架和相关的扩展组件（库和工具包），可以帮助你省去游戏开发枯燥中的重复劳动和底层逻辑的开发。Pomelo 不但适用于游戏服务器开发， 也可用于开发高实时 Web 应用，它的分布式架构可以使 Pomelo 比普通的实时 Web 框架扩展性更好。

kbengine

一款开源的游戏服务端引擎，使用简单的约定协议就能够使客户端与服务端进行交互，使用KBEngine插件能够快速与(Unity3D, OGRE, Cocos2d, HTML5, 等等)技术结合形成一个完整的客户端。

服务端底层框架使用c++编写，游戏逻辑层使用Python(支持热更新)，开发者无需重复的实现一些游戏服务端通用的底层技术，将精力真正集中到游戏开发层面上来，快速的打造各种网络游戏。

(经常被问到承载上限，kbengine底层架构被设计为多进程分布式动态负载均衡方案，理论上只需要不断扩展硬件就能够不断增加承载上限，单台机器的承载上限取决于游戏逻辑本身的复杂度。)
