Food_Delivery_Microservices_Application

A food delivery application system allows users to browse items and order food online in an easy and efficient manner

Summary

This microservices is created to demonstrate how to split sample Spring application into microservices. To achieve that goal I use Spring Cloud Gateway, Spring Cloud Circuit Breaker, Resilience4j, Retry Module, Rate Limiter, Feign Client and the Eureka Service Discovery Client/Server from the Spring Cloud Netflix technology stack.
