阿里巴巴Dubbo分布式服务框架已开源

Dubbo Overview:

Serving 1,000+ services with 1,000,000,000+ invocations everyday, Dubbo becomes the key part of Alibaba's SOA solution and has been deployed to the whole alibaba.com family:



So, What is Dubbo?

Dubbo [ ] is a service framework enpowers applications with service import/export capability with high performance RPC.
It's composed of three kernel parts:

• Remoting: a network communication framework provides sync-over-async and request-response messaging.
• RPC: a remote procedure call abstraction with load-balancing/failover/clustering capabilities.
• Registry: a service directory framework for service registration and service event publish/subscription

Dubbo can:

• Integrate different types of RPC solutions(RMI/Hessian...) with unified behavior by the abstraction layer of RPC
• Support out-of-box, plug-able load balancing and fault tolerance strategies.
• Achieve graceful service upgrade/downgrade with service registry.

Dubbo Example:
1. Export a remote service:

<bean id="xxxService" class="com.xxx.XxxServiceImpl" /> 
<dubbo:service interface="com.xxx.XxxService" ref="xxxService" />

2. Reference a remote service:

<dubbo:reference id="xxxService" interface="com.xxx.XxxService" />
<bean id="xxxAction" class="com.xxx.XxxAction">
    <property name="xxxService" ref="xxxService" />
</bean>

相对于阿里前段时间开源的几个产品，Dubbo算是比较大的框架类产品，在阿里内部实施面较广，可靠性较高，基本可以放心使用。

和淘宝(taobao)HSF框架有什么区别？

同问

同类产品，一个用在taobao.com，一个用在alibaba.com，都是阿里系的。

但是来个问题dubbo的rpc服务如何让其它语言如：php,ruby,python等语言调用，支持多语言客户端？

与hessian的对比 ？

这个东西开源对我们程序员有什么意义?

没得说，精华一枚。
