When everything is healthy the request flow can look like this: When one of many backend systems becomes latent it can block the entire user request: With high volume traffic a single backend dependency becoming latent can cause all resources to become saturated in seconds on all servers. Now add a SpringBootApplication class. In distributed systems, there is one effectwhere the unavailability of one service or some services will lead to the service unavailability of the whole system, this is called service avalanche effect. 2023 Micha Trojanowski The @FeignClient annotation and the @EnableFeignClients annotation do not actually require any additional dependencies at compile-time, but they will require the below spring-cloud-starter-openfeign dependency at runtime and Feign integrates with Ribbon and Eureka automatically.
