+# Пример работы двух микросевисов с использованием Config server, Eureka, Zuul, Feign client
+
+## Сервер конфигурации (config-server, порт: 8888)
+* Хранит настройки всех приложений
+* Реализован с помощью Spring Config Server
+
+## Реестр служб (service-discovery-server, порт: 8761)
+* Помогает службам (приложениям/микросервисам) находить дург-друга
+* Реализован с помощью Eureka
+
+## Микросервис приветствий (greeting-microservice, порт: 8081)
+Здоровается тремя способами:
+* Простое приветствие, зашитое прямо в коде
+* Приветствие полученное из настроек (@Value)
+* Приветствие от человека, имя которого взято с микросервиса имен. Для получения имени от стороннего API используется FeignClient
+
+## Микросервис имен (names-microservice, порт: 8082)
+* Отдает случайное имя из константного массива, 
+* Прибавляет к нему форму обращения из настроек (@Value)
+
+## API шлюз (facade-gateway, порт: 8080)
+* Объединяет API обоих микросервисов в одно
+* Полученное общее API накрывает Spring Security
+* Реализован с помощью Zuul
