+# Отчет. Лабораторная работа 4
+
+## Описание
+
+В ходе лабораторной работы были изучены главы туториала по работе с RabbitMQ, в результате чего получен отчет о выполнении заданий каждой главы, представленный на скриншотах в папке /images:
+
+- Первый туториал:
+  ![Tutorial-1](./images/Tutorial-1.png)
+- Второй туториал:
+  ![Tutorial-2](./images/Tutorial-2.png)
+- Третий туториал:
+  [Tutorial-3](./images/Tutorial-3.png)
+
+Чтобы продемонстрировать работу сервисов посредством ассинхронного общения через брокер сообщений RabbitMQ была выбрана предметная область администрирования компьютеров, где мы отслеживаем события включения компьютеров.
+
+Сервис-издатель "Publisher" публикует в очередь сообщений событие поступления заказа с некоторым номером. Сервисы-подписчики обрабатывают сообщения о заказах, при этом подписчики обрабатывают сообщение по-разному: один вид подписчика обрабатывает его со задержкой несколько секунд, другой - "мгновенно", они получают одни и те же сообщения, но соединены с разными очередями.
+
+В качестве эксперимента изначально были запущены по одному экземпляру каждого вида. На Consumer2.png представлена работа мгновенно обрабатывающего подписчика, справляющегося с нагрузкой без увеличения размера очереди:
+![Consumer 2](./images/Consumer2.PNG)
+На Consumer1.png представлена работа подписчика, обрабатывающего сообщения с задержкой. В очереди накапливаются сообщения в состоянии 'Ready', которые готовы для того чтобы быть доставленными подписчикам. Сервис не справляется с нагрузкой, так как отправляются сообщения быстрее, чем обрабатываются:
+![Consumer 1](./images/Consumer1.PNG)
+Чтобы обеспечить равную скорость отправки и обработки, увеличивается количество экземпляров-подписчиков данного типа до трех. На Consumer1-scaling.png видно, что теперь длина очереди не растет и система справляется с поступающими сообщениями. Скорость "publish" и "consumer ack" также становится равной:
+![Consumer 1](images/Consumer1-3_replicas.png)
+
+## Как запустить
+
+Для того, чтобы запустить сервисы, необходимо выполнить следующие действия:
+
+1. Установить и запустить Docker Engine или Docker Desktop
+2. Через консоль перейти в папку, в которой расположен файл docker-compose.yml
+3. Выполнить команду для запуска брокера сообщений rabbitmq:
+
+```
+docker compose up rabbit -d
+```
+
+4. Выполнить команду для запуска остальных контейнеров:
+
+```
+docker compose up -d
+```
+
+Такой порядок запуска важен для того, чтобы брокер сообщений успел полностью запуститься и произвести действия для того, чтобы быть готовым принимать соединения от сервисов. Потому что указания depends_on не хватает для отслеживания завершения всех необходимых подготовительных процессов брокера.
+
+## Видео-отчет

+# RabbitMQ Tutorial Using Spring AMQP
+
+This project implements each of the [6 RabbitMQ Tutorials][1] using Spring AMQP.
+
+It is a CLI app that uses Spring Profiles to control its behavior.  Each tutorial is a trio of classes:
+sender, receiver, and configuration.
+
+[1]: https://www.rabbitmq.com/getstarted.html
+
+## Prerequisites
+These tutorials assume RabbitMQ is [installed](https://rabbitmq.com/download.html) and running
+on `localhost` using the standard port (`5672`). In case you use
+a different host, port or credentials, connections settings would require adjusting.
+
+## Usage
+
+These tutorials use Maven. To build them run
+
+```
+./mvnw clean package
+```
+The app uses Spring Profiles to control what tutorial it's running, and if it's a
+Sender or Receiver. Choose which tutorial to run by using these profiles:
+
+- {tut1|hello-world},{sender|receiver}
+- {tut2|work-queues},{sender|receiver}
+- {tut3|pub-sub|publish-subscribe},{sender|receiver}
+- {tut4|routing},{sender|receiver}
+- {tut5|topics},{sender|receiver}
+- {tut6|rpc},{client|server}
+
+After building with maven, run the app however you like to run boot apps.
+
+For example:
+
+```
+java -jar target/rabbitmq-tutorials.jar --spring.profiles.active=work-queues,sender
+```
+
+will run the publisher part of tutorial 2 (Work Queues).
+
+For tutorials 1-5, run the consumer (receiver) followed by the publisher (sender):
+
+```
+# shell 1
+java -jar target/rabbitmq-tutorials.jar --spring.profiles.active=work-queues,receiver
+
+# shell 2
+java -jar target/rabbitmq-tutorials.jar --spring.profiles.active=work-queues,sender
+```
+
+For tutorial 6, run the server followed by the client.
+
+You can find more usage instructions by running the following command:
+
+```
+java -jar target/rabbitmq-tutorials.jar
+```
+
+This will display the following message:
+
+```
+This app uses Spring Profiles to control its behavior.
+
+Options are:
+java -jar target/rabbitmq-tutorials.jar --spring.profiles.active=hello-world,receiver
+java -jar target/rabbitmq-tutorials.jar --spring.profiles.active=hello-world,sender
+java -jar target/rabbitmq-tutorials.jar --spring.profiles.active=work-queues,receiver
+java -jar target/rabbitmq-tutorials.jar --spring.profiles.active=work-queues,sender
+java -jar target/rabbitmq-tutorials.jar --spring.profiles.active=pub-sub,receiver
+java -jar target/rabbitmq-tutorials.jar --spring.profiles.active=pub-sub,sender
+java -jar target/rabbitmq-tutorials.jar --spring.profiles.active=routing,receiver
+java -jar target/rabbitmq-tutorials.jar --spring.profiles.active=routing,sender
+java -jar target/rabbitmq-tutorials.jar --spring.profiles.active=topics,receiver
+java -jar target/rabbitmq-tutorials.jar --spring.profiles.active=topics,sender
+java -jar target/rabbitmq-tutorials.jar --spring.profiles.active=rpc,client
+java -jar target/rabbitmq-tutorials.jar --spring.profiles.active=rpc,server
+```
+
+## Configuration
+
+When running receivers/servers it's useful to set the duration the app runs to a longer time.  Do this by setting
+the `tutorial.client.duration` property.
+
+```
+java -jar target/rabbitmq-tutorials.jar --spring.profiles.active=tut2,receiver,remote --tutorial.client.duration=60000
+```
+
+By default, Spring AMQP uses localhost to connect to RabbitMQ.  In the
+sample, the `remote` profile causes Spring to load the properties in
+`application-remote.yml` that are used for testing with a non-local
+server.  Set your own properties in the one in the project, or provide
+your own on the command line when you run it.
+
+To use to a remote RabbitMQ installation set the following properties:
+
+```
+spring:
+  rabbitmq:
+    host: <rabbitmq-server>
+    username: <tutorial-user>
+    password: <tutorial-user>
+```
+
+To use this at runtime create a file called `application-remote.yml` (or properties) and set the properties in there.  Then set the
+remote profile as in the example above.  See the [Spring Boot](https://docs.spring.io/spring-boot/docs/current/reference/htmlsingle/)
+and [Spring AMQP documentation](https://docs.spring.io/spring-amqp/reference/html/) for more information on setting application
+properties and AMQP properties specifically.
