 # pulsar
 
 #### 介绍
-Pulsar is a distributed pub-sub messaging platform with a very flexible messaging model and an intuitive client API.
+Apache Pulsar 是一个企业级的发布订阅（pub-sub）消息系统。向Pulsar发送数据的应用程序叫做生产者（producer），而从Pulsar读取数据的应用程序叫做消费者（consumer）。有时候消费者也被叫作订阅者。主题（topic）是Pulsar的核心资源，一个主题可以被看成是一个通道，消费者向这个通道发送数据，消费者从这个通道拉取数据。
 
 #### 软件架构
-软件架构说明
+Apache Pulsar 集群由两层组成：
+无状态服务层，由一组接收和传递消息的 Broker 组成
+有状态存储层，由一组名为 bookies 的 Apache BookKeeper 存储节点组成，可持久化地存储消息
+通过分层架构实现了存储和计算分离
+另外使用Apache Zookeeper进行元数据管理
