Akka is a concurrency framework built around the notion of actors and composable futures, Akka was inspired by Erlang which was built from the ground up around the Actor paradigm. It would usually be used to replace blocking locks such as synchronized, read write locks and the like with higher level asynchronous abstractions. Akka是一个建立在Actors概念和可组合Futures之上的并发框架，,Akka设计灵感来源于Erlang，Erlang是基于Actor模型构建的。它通常被用来取代阻塞锁如同步、读写锁及类似的更高级别的异步抽象。 Netty is an asynchronous network library used to make Java NIO easier to use. Netty是一个异步网络库，使JAVA NIO的功能更好用。 Notice that they both embrace asynchronous approaches, and that one could use the two together, or entirely separately. 注意：它们两个都提供了异步方法，你可以使用其中一个，或两个都用 Where there is an overlap is that Akka has an IO abstraction too, and Akka can be used to create computing clusters that pass messages between actors on different machines. From this point of view, Akka is a higher level abstraction that could (and does) make use of Netty under the hood Akka针对IO操作有一个抽象，这和netty是一样的。使用Akka可以用来创建计算集群,Actor在不同的机器之间传递消息。从这个角度来看,Akka相对于Netty来说，是一个更高层次的抽象 转载地址：http://cvdfx.baihongyu.com/
