Example of a microservice architecture using Spring Cloud
The architecture is composed by eight services:
discovery-service: Service Discovery Server created with Eurekaapi-gateway: API Gateway created with Zuul that uses thediscovery-serviceto send the requests to the services. It uses Ribbon as Load Balanceruser-service: REST service created with Spring Boot for User related servicesvehicle-service: REST service created with Spring Boot for Vehicle related serviceszone-service: Simple REST service created with Spring Boot for Zones related servicesbooking-service: Simple REST service created with Spring Boot for booking related serviceshelp-service: Simple REST service created with Spring Boot for help related servicesreport-service: Simple REST service created with Spring Boot for generating reports for all the data
The services are already configured with Hystrix (latency and fault tolerance library) and are providing a stream that you can use to monitor with a Hystrix/Turbine dashboard. You can check the Hystrix Stream accessing the service URL with /hystrix.stream (example: http://localhost:8765/hystrix.stream)
To test this architecture you will need to have: JDK 8+, Docker and Maven installed
-
Clone this repo and enter it
-
Run the
start.shscript, it will use Maven to build the.jarfile for each service and then use Docker to build the containers with the.jarfiles
In the default configuration you will have:
- Discovery Service running on port
8761, accesshttp://localhost:8761to see the dashboard - API Gateway running on port
8765, you will send the requests to this service - User Services running on ports:
8091 - Vehicle Services running on ports:
8092 - Zone Services running on ports:
8093 - Booking Services running on ports:
8094 - Help Services running on ports:
8095 - Report Services running on ports:
8096
After running the containers, head to http://localhost:8761 to make sure that the four services are registered in the Discovery Service.
