# Лабораторная работа 4
## Описание
Данная лабораторная работа предназначена для изучения проектирования приложений при помощи брокера сообщений.
### Уроки из RabbitMQ Tutorials
1. ![img.png](images/img1.png)
2. ![img.png](images/img2.png)
3. ![img.png](images/img3.png)
### Задание
Ссылка на демонстрацию работы программы: https://vk.com/video215756667_456239454?list=ln-IJETwWy23zLuysjetJ
## Выводы
1. Запуск 1 и 2 Consumer'а: Consumer-2 (без задержки) график Queued Messages держится на нуле, в то время как у Consumer-1 график возрастает (скорость обработки сообщений < 1 с).
2. Запуск 2 первых Consumer'ов: обрабатывают сообщения последовательно и накапливают очередь.
