## 写在前面 ##

这里说的几种是基于注册中心还有相关组件的区别，有些组件是被广泛应用的，

## 一、SpringCloud Netflix ##

这个应该是业界使用最多的架构了

Spring Cloud Netflix通过自动装配集成到SpringBoot和SpringCloud的开发中，自己实现很多组件的封装，包括

### 1.1、Eureka ###

注册中心，用于服务的注册和发现

### 1.2、Hystrix ###

断路器，用于服务的断路配置

### 1.3、Ribbon ###

Client Side Load Balancer，客户端的负载均衡器

### 1.4、Zuul ###

路由器和过滤器：Zuul过滤器的自动重新注册，以及用于反向代理创建的简单配置约定

## 二、SpringCloud + Consul ##

Consul 是用Go语言写的，对 提供了Java客户端操作

这种微服务架构，基于Consul-config作为服务的注册和发现，基于Consul-discovery作为分布式配置的统一管理。

### 2.1、代码演示 ###

代码比较多，先略在这里，后面我整理到Github上

## 三、SpringCloud Alibaba ##

这种微服务架构，基于Nacos-discovery作为服务的注册和发现，基于Nacos-config作为分布式配置的统一管理。基于Sentinel作为服务监控，包括熔断和降级规则的配置。

### 3.1、Nacos ###

是阿里团队封装实现的的用于微服务架构中，用于服务注册和发现，以及分布式的配置管理的Nacos Server。

*  集成 Jar,包括Spring Web,SpringSecurity，Apache基础工具包，Mina和Netty等等
 *  用于分布式配置管理的部分，是使用了Derby轻型的可嵌入式的关系型数据库，数据库设计，包括了

整体设计，还挺复杂的，可以比较下，携程团队实现的分布式配置 Appolo

### 3.2、Sentinel,服务的降级和限流规则配置 ###

Web页面，可实现在页面上配置服务的降级和限流规则，前端是基于Angular实现

Nacos 和 Sentinel，淘宝团队并没有开源代码，我是通过反编译工具看到的相关信息，这里不做太多深究了

### 3.3、代码演示 ###

代码比较多，先略在这里，后面我整理到Github上

## 四、SpringCloud Google ##
