第一个是高并发,第二个是如何优化
![高性能网关Zuul](/docs/distributed-system/images/gateway-high-concurrency.png)
**Zuul**网关部署的是什么配置的机器,**部署32核64G对网关路由转发的请求****每秒抗个小几万请求是不成问题的几台Zuul网关机器**
**每秒是1万请求8核16G的机器部署Zuul网关5台机器就够了**
### 生产级的网关,应该具备我刚才说的几个特点和功能:
#### (1)动态路由:新开发某个服务,动态把请求路径和服务的映射关系热加载到网关里去;服务增减机器,网关自动热感知
#### (2)灰度发布:基于现成的开源插件来做
#### (3)授权认证
#### (4)限流熔断
#### (5)性能监控每个API接口的耗时、成功率、QPS
#### (6)系统日志
#### (7)数据缓存
