服務(wù)網(wǎng)關(guān)是微服務(wù)架構(gòu)中一個(gè)不可或缺的部分。通過服務(wù)網(wǎng)關(guān)統(tǒng)一向外系統(tǒng)提供REST API的過程中，除了具備服務(wù)路由、均衡負(fù)載功能之外，它還具備了權(quán)限控制等功能。Spring Cloud Netflix中的Zuul就擔(dān)任了這樣的一個(gè)角色，為微服務(wù)架構(gòu)提供了前門保護(hù)的作用，同時(shí)將權(quán)限控制這些較重的非業(yè)務(wù)邏輯內(nèi)容遷移到服務(wù)路由層面，使得服務(wù)集群主體能夠具備更高的可復(fù)用性和可測試性。
