+# 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)
