[Spring Camp 2018] 11번가 Spring Cloud 기반 MSA로의 전환 : 지난 1년간의 이야기
The document discusses strategies for implementing microservices architecture (MSA) using various components such as Hystrix for circuit breaking, Eureka for service discovery, and Zuul as an API gateway. It emphasizes the importance of resilience in inter-service communication and outlines configurations for these technologies. The document also reflects on past experiences and challenges faced during its implementation.
