+# Лабораторная работа 4 - Работа с брокером сообщений
+## ПИбд-42 || Алейкин Артем
+
+### Описание
+В данной лабораторной работе мы познакомились с такой утилитой как RabbitMQ.
+
+### Туториалы
+1. HelloWorld - Tutorial
+![Консольный вывод - первый туториал](./Images/Туториал_1.png)
+
+2. Work Queues - Tutorial
+![Консольный вывод - второй туториал](./Images/Туториал_2.png)
+
+3. Publish/Subscribe - Tutorial
+![Консольный вывод - третий туториал](./Images/Туториал_3.png)
+
+### Основное задание
+Было разработано 3 приложения: Publisher, Consumer1 и Consumer2.
+Первое отвечало за доставку сообщений в очереди. Оно генерирует одно сообщение раз в секунду.
+Второе и Третье за обработку этих сообщений из очередей, но Consumer1 имел искусственную задержку в 2-3 секунды, в то время как Consumer2 таких ограничений не имел и работу.
+
+### Шаги для запуска:
+1. Запуск контейнеров:
+```
+docker-compose up -d
+```
+
+В результате мы можем посмотреть графики по этой ссылке http://localhost:15672/
+![График Consumer1 - медленный](./Images/Лаба_Отчет2.png)
+![График Consumer2 - быстрый](./Images/Лаба_Отчет1.png)
+
+После этого было добавлено еще 3 клиента типа Consumer1 и только после этого их суммарной производительности стало хватать для обработки сообщений.
+![График Consumer1 для нескольких клиентов - медленный](./Images/Лаба_Отчет3.png)
+![График Consumer2 - быстрый](./Images/Лаба_Отчет4.png)

-# Лабораторная работа №4: Работа с брокером сообщений (RabbitMQ)
-
-## Цель
-
-Изучение проектирования приложений с использованием брокера сообщений RabbitMQ.
-
----
-
-## Задачи
-
-> 1. **Установить RabbitMQ**  
-     Установите RabbitMQ на локальный компьютер (или используйте Docker).
->- [Скачивание RabbitMQ](https://www.rabbitmq.com/download.html)
->- [Релизы RabbitMQ](https://github.com/rabbitmq/rabbitmq-server/releases/)
->- **Пройти уроки RabbitMQ**
->- Сделайте скриншоты, показывающие запуск `producer` и `consumer` и передачу сообщений.

-### Лабораторная работа №4 - Работа с брокером сообщений
-
-#### Задание
-
-1. Установить брокер сообщений RabbitMQ.
-2. Пройти уроки 1, 2 и 3 из RabbitMQ Tutorials на любом языке программирования.
-3. Продемонстрировать работу брокера сообщений.
-
-#### Описание работы программы:
-
-- **Класс Publisher** успешно осуществляет отправку сообщений своим клиентам.
-  
-- **Класс Consumer1** принимает и обрабатывает сообщения с задержкой в 3 секунды, что можно заметить на видео.
-
-- **Класс Consumer2** мгновенно принимает и обрабатывает сообщения.
