服务雪崩效应

# 1.服务雪崩
- 在微服务之间进行服务调用是由于某一个服务故障，导致级联服务故障的现象，称为雪崩效应。雪崩效应描述的是提供方不可用，导致消费方不可用并将不可用逐渐放大的过程。
# 2.图解雪崩效应
- 如存在如下调用链路:
- 而此时，Service A的流量波动很大，流量经常会突然性增加！那么在这种情况下，就算Service A能扛得住请求，Service B和Service C未必能扛得住这突发的请求。此时，如果Service C因为抗不住请求，变得不可用。那么Service B的请求也会阻塞，慢慢耗尽Service B的线程资源，Service B就会变得不可用。紧接着，Service A也会不可用，这一过程如下图所示
