I understand that Eureka is meant for service discovery, but what if I have multiple instances running for the same service registered in eureka server? Let's say I have three instances registered in Eureka server for the same service. Then, If I consume the service, I get random instances returned from Eureka. Does this mean Eureka uses random approach for load balancing? If yes, is it possible to modify it to use round-robin approach? Appreciate if you have any findings.

Default is ribbon and it can be disabled as below

spring.application.name=client
spring.cloud.loadbalancer.ribbon.enabled=false

this then defaults to Spring Loadbalancer where you can create custom @LoadBalancerClient and pass your own config
