Apache Qpid 消息中间件
Qpid 是 Apache 开发的一款面向对象的消息中间件，它是一个 AMQP 的实现，可以和其他符合 AMQP 协议的系统进行通信。Qpid 提供了 C++/Python/Java/C# 等主流编程语言的客户端库，安装使用非常方便。相对于其他的 AMQP 实现，Qpid 社区十分活跃，有望成为标准 AMQP 中间件产品。除了符合 AMQP 基本要求之外，Qpid 提供了很多额外的 HA 特性，非常适于集群环境下的消息通信。
Apache Qpid JMS 0.21.0 发布了，
该版本支持 Advanced Message Queuing Protocol 1.0 (AMQP 1.0, ISO/IEC 19464,http://www.amqp.org)。
