This sample demonstrates Spring Cloud microservice architecture:

Eureka service registry
Eureka clients
RESTful load balanced communication between microservices
Circuit breaker
Sleuth tracing and Zipkin collector service
Performance optimization: dog-service calls dog-name-service and dog-breed-service in parallel

Prerequisites

Must be installed locally

Java 17
Docker

Local run

Eureka service registry

cd service-registry
gradlew bootRun

Eureka console is available at http://localhost:8761

Dog name microservice

cd dog-name-service
gradlew bootRun

Returns a random dog name

Dog breed microservice

cd dog-breed-service
gradlew bootRun

Returns a random dog breed

Dog microservice

cd dog-service
gradlew bootRun

Dog microservice displays a random dog name and a random dog breed obtained from dog-name-service and dog-breed-service respectively: http://localhost:8080/api/random

If dog-name-service or dog-breed-service is not running, the circuit breaker falls back to the default dog name and breed

Zipkin collector service

docker run -d -p 9411:9411 openzipkin/zipkin

Zipkin console is available at http://localhost:9411
