+# Лабораторная работа №3.
+
+## Задание
+
+- Создать 2 микросервиса, реализующих CRUD на связанных сущностях.
+- Реализовать механизм синхронного обмена сообщениями между микросервисами.
+- Реализовать шлюз на основе прозрачного прокси-сервера nginx.
+
+Вариант: геоданные и пользователи
+
+## Выбранные сервисы
+
+Были написаны два сервиса на языке python с технологией flask:
+
+- Сервис geodata_service, хранящий геоданные и реализующий CRUD операции с ними через HTTP запросы.
+- Сервис user_service, хранящий данные о пользователях и реализующий CRUD операции с ними через HTTP запросы.
