ZeroRPC简介 - 轻量级分布式通信框架

概述

分布式系统的核心是分布式通信，而传统上开发一套支持上千台规模集群，可靠性非常高的分布式通信框架，需要不少的精力投入。而在多数情景下，我们（特别是时间宝贵的OP）并不是非常关注技术实现的细节，而是希望有一套成熟、轻量、可靠性高、使用方便而且易于调试的分布式通信框架，可以直接使用，从而把时间放在具体业务逻辑上。

在PyCon 2012大会上，dotcloud公司开源了一套基于ZeroMQ和MessagePack的分布式通信框架（或者说是协议+Python实现）。该框架因为基于ZeroMQ，使用方法是RPC，所以被命名为ZeroRPC。ZeroRPC的特点在其官网的介绍中一目了然[1]：

ZeroRPC is a light-weight, reliable and language-agnostic library for distributed communication between server-side processes.
