SpringOne Platform 2017 Adar Danait, Citi; Lillian Ernest, Citi "The application ecosystem for our business consists of 700+ services. A typical transaction request flows through 5+ service instances before its processed. In this distributed environment, inevitably some of the many service dependencies will fail. Each dependent service invocation is costly and a single failure can lead to diminished user experience and a lower Net Promoter Score for us either on the mobile app or desktop. It also places a higher stress on the underlying system that is attempting to recover from the failure.

During this session you will learn: Hystrix Circuit breaker mechanism How to use Hystrix in microservices Hystrix best practices and recommendations"
