This is a suuuper basic Voter Dashboard app that aggregates real-time data from 2 separate teams ("Red" squad and "Blue" squad) and displays it in a visualization. The microservices collect voting data and send it to the front-end app via an API Gateway. To do this, it utilizes:
- Spring Webflux for reactive web API;
- Spring Cloud Consul Discovery for service discovery;
- Spring Cloud Loadbalancer for client-side loadbalancing;
- Spring Cloud CircuitBreaker + Resilience4j for circuit-breaking;
- Spring Cloud Gateway for API Gateway.
Other enhancements that can be easily introduced:
- Spring Cloud Config for externalized configuration;
- Spring Cloud Sleuth & Spring Cloud Zipkin for distributed tracing;
- Spring Cloud Rabbit for messaging;
- Spring Cloud Contract for contract testing;
- etc...
