+# Лабораторная работа №4 - Работа с брокером сообщений
+
+**Цель**: изучение проектирования приложений при помощи брокера сообщений.
+
+**Задачи**:
+
+1. Установить брокер сообщений RabbitMQ.
+2. Пройти уроки 1, 2 и 3 из [RabbitMQ Tutorials](https://www.rabbitmq.com/getstarted.html) на любом языке программирования.
+3. Продемонстрировать работу брокера сообщений.
+
+## Установка брокера сообщений RabbitMQ
+
+Можно не использовать Docker и использовать локальный ПК.
+
+[Страница скачивания RabbitMQ с офф. сайта](https://www.rabbitmq.com/download.html).
+
+[Страница релизов RabbitMQ](https://github.com/rabbitmq/rabbitmq-server/releases/), где есть бинарные установщики для всех современных платформ.
+
+## Прохождение tutorial
+
+Достаточно для каждого урока скриншота, где виден запуск одновременно `producer` и `consumer`, а также видно, что сообщения передаются.
+
+## Разработка демонстрационных приложений
+
+См. 3 главу tutorial.
+
+Необходимо выбрать предметную область и разработать следующие приложения:
+
+1. **Publisher**.
+  Программа, которая создаёт один **exchange** с типом _fanout_.
+  Программа должна раз в секунду генерировать сообщения в журнал событий согласно вашей предметной области.
+  Например, событие "пришёл заказ" или "сообщение от пользователя" или "необходимо создать отчёт".
+2. **Consumer 1**.
+  Программа, которая создаёт под себя отдельную не анонимную (!) очередь (**queue**) (то есть имя queue НЕ пустая строка), создаёт **binding** на **exchange** и начинает принимать сообщения (_consume_).
+  Программа должна обрабатывать сообщения 2-3 секунды.
+  Можно реализовать через обычный _Thread.Sleep_ (для C#).
+3. **Consumer 2**.
+  Аналогично _Consumer 1_, только сообщения необходимо обрабатывать моментально.
+  Только имя очереди должно отличаться от _Consumer 1_.
+
+Далее необходимо собрать и запустить приложения одновременно по одному экземпляру.
+
+Сделать в отчёте вывод о скорости обработки _consumer_-ами событий от _publisher_-а.
+Для этого можно посмотреть заполненность созданных очередей.
+А для этого можно использовать скриншот из **RabbitMQ Management UI**.
+
+Запустить несколько копий _Consumer 1_.
+Проверить заново заполненность очередей через _UI_.
+
+## Правила оформления pull request
+
+Код и отчёт со скриншотами необходимо положить в папку `tasks/фамилия-инициалы/lab_4`.
+
+Не забудьте о файле `.gitignore`, чтобы не закоммитить ничего лишнего.
+Для C#-проектов это, например, папки `bin` и `obj`.
+
+Правила именования ветки: `фамилия-инициалы-lab-номер`, например, `moiseev-vv-lab-4`.
+
+Название pull request: `[Л/Р 4] ФАМИЛИЯ ИМЯ`, например, `[Л/Р 4] Моисеев Владислав`.

+
+## Задачи
+
+Написать небольшое эссе (буквально несколько абзацев) своими словами. А помогут Вам в этом вопросы из списка: 
+1. Какие алгоритмы и методы используются для балансировки нагрузки?
+2. Какие открытые технологии существуют для балансировки нагрузки?
+3. Как осуществляется балансировка нагрузки на базах данных?
+4. Реверс-прокси как один из элементов балансировки нагрузки.
+
+## Эссе
+
+Балансировка нагрузки – это важный процесс в сфере информационных технологий, который позволяет равномерно распределять нагрузку между компьютерами, серверами или другими ресурсами для обеспечения оптимальной производительности системы. В данном эссе я рассмотрю несколько вопросов, связанных с алгоритмами и методами балансировки нагрузки, открытыми технологиями, а также балансировкой нагрузки на базах данных и использованием реверс-прокси.
+
+Первый вопрос касается алгоритмов и методов, используемых для балансировки нагрузки. Существует несколько подходов, таких как раунд-робин, весовая нагрузка, наименьшее количество соединений и IP хэширование. Раунд-робин распределяет запросы по всем доступным серверам одинаковым образом. Весовая нагрузка позволяет приоритезировать определенные серверы и передавать им больше запросов. Наименьшее количество соединений выбирает сервер с наименьшим количеством активных соединений. IP хэширование использует IP-адрес клиента для определения сервера, который будет обрабатывать его запросы.
+
+Второй вопрос касается открытых технологий для балансировки нагрузки. Среди них можно выделить HAProxy, NGINX, Apache HTTP Server и AWS Elastic Load Balancer. HAProxy является высокопроизводительным реверс-прокси, который поддерживает различные алгоритмы балансировки нагрузки. NGINX также является реверс-прокси и обладает возможностями балансировки нагрузки. Apache HTTP Server предоставляет модуль mod_proxy_balancer для балансировки нагрузки. AWS Elastic Load Balancer предоставляет гибкую и масштабируемую балансировку нагрузки в облачной среде.
+
+Третий вопрос касается балансировки нагрузки на базах данных. Для балансировки нагрузки на базах данных используются различные методы, такие как горизонтальное шардирование, репликация и кэширование. Горизонтальное шардирование разделяет данные на несколько фрагментов и распределяет их по разным серверам. Репликация создает копии базы данных на разных серверах для обработки запросов. Кэширование позволяет хранить результаты часто используемых запросов для улучшения производительности.
+
+Реверс-прокси является важным элементом балансировки нагрузки. Он работает на стороне сервера и перенаправляет запросы с клиента на разные серверы в зависимости от текущей нагрузки. Реверс-прокси предоставляет централизованную точку контроля над серверами, обеспечивает отказоустойчивость и улучшает производительность системы.

+## REST API, Gateway и синхронный обмен между микросервисами
+
+## Создание микросервисов
+
+1. С помощью команды `dotnet new web -n worker-2` в терминале создал первый микросервис.
+2. Добавил решение командой  `dotnet new sln`
+3. Связал решение и проект командой `dotnet sln worker-2.sln add worker-2.csproj`
+4. Повторил действие для второго микросервиса
+5. Добавил библиотеку Swagger и OpenAi в проекты и запустил с помощью команды `dotnet run`
+
+Скриншоты протестированных микросервисов:
+![](pic/1.png) 
+![](pic/2.png)
+![](pic/4.png)
+
+## Реализация синхронного обмена
+
+Реализовал код, который вызывает сихронно данные из соседнего микросервиса.
+
+```cs
+//worker-2
+app.MapGet("/Locations/", async () =>
+{
+    var httpClient = new HttpClient();
+    var secondWorkerResponse = await httpClient.GetStringAsync("http://worker-1:8080/");
+
+    return secondWorkerResponse.ToArray();
+})
+.WithName("GetBreeds")
+.WithOpenApi();
+
+
+## Реализация gateway при помощи nginx
+
+Добавил nginx.conf:
+
+```conf
+server {
+    listen       8080;
+    listen  [::]:8080;
+    server_name  localhost;
+
+    location / {
+        root   /usr/share/nginx/html;
+        index  index.html index.htm;
+    }
+
+    location /worker-1/ {
+        proxy_pass       http://worker-1:8080/;
+        proxy_set_header Host      $host;

+
+## Разработка демонстрационных приложений
+
+Предметная область: Дополенительные соглашения и договора на заселение в отель Туристического агентства.
+Разработа три приложения согласно предметной области.
+
+1. Publisher
+
+```py
+import pika
+import time
+import random
+
+collection = ["Application for Travel Agency", "Buying tickets", "Execution of the agreement", "Check-into a hotel"]
+
+connection = pika.BlockingConnection(pika.ConnectionParameters('localhost'))
+channel = connection.channel()
+
+channel.exchange_declare(exchange='Agreements', exchange_type='fanout')
+
+while True:
+    message = f"Message: {random.choice(collection)}"
+
+    channel.basic_publish(exchange='Agreements', routing_key='', body=message)
+
+    time.sleep(1)
+
+connection.close()
+```
+
+2. Consumer 1.
+
+```py
+import pika
+import time
+
+def process_message(ch, method, properties, body):
+    print(f"Получено сообщение: {body}")
+    time.sleep(3)
+    print("Сообщение успешно обработано")
+
+connection = pika.BlockingConnection(pika.ConnectionParameters('localhost'))
+channel = connection.channel()
+
+result = channel.queue_declare(queue='', exclusive=True)
+queue_name = result.method.queue
+
+channel.queue_bind(exchange='Agreements', queue=queue_name)
+
+channel.basic_consume(queue=queue_name, on_message_callback=process_message, auto_ack=True)
+
+print('Ожидание сообщений...')
+channel.start_consuming()
+```
+
+3. Consumer 2.
+
+```py
+import pika
+
+
+def process_message(ch, method, properties, body):
+    print(f"Получено сообщение: {body}")
+    print("Сообщение успешно обработано")
+
+connection = pika.BlockingConnection(pika.ConnectionParameters('localhost'))
+channel = connection.channel()
+
+result = channel.queue_declare(queue='', exclusive=True)
+queue_name = result.method.queue
+
+channel.queue_bind(exchange='Agreements', queue=queue_name)
+
+channel.basic_consume(queue=queue_name, on_message_callback=process_message, auto_ack=True)
+
+print('Ожидание сообщений...')
+channel.start_consuming()
+```
+
+## Результаты выполнения лабораторной работы
+
+Результат отработки Consumer_1:
+
+![](scrins/maintask1.png)
+
+Результат отработки Consumer_2:
+
+![](scrins/maintask2.png)
+
+![](scrins/maintask_dop.png)
+
+Вывод: Consumer_2 нагружает меньше памяти, чем Consumer_1 и принимает сообщения гораздо быстрее, тем самым не позволяя очереди накапливать огромное количество сообщений.

+## Задачи
+
+Написать небольшое эссе (буквально несколько абзацев) своими словами. А помогут Вам в этом вопросы из списка: 
+1. Зачем сложные системы (например, социальная сеть ВКонтакте) пишутся в "распределенном" стиле, где каждое отдельное приложение (или сервис) функционально выполняет только ограниченный спектр задач?
+2. Для чего были созданы системы оркестрации приложений? Каким образом они упрощают / усложняют разработку и сопровождение распределенных систем?
+3. Для чего нужны очереди обработки сообщений и что может подразумеваться под сообщениями?
+4. Какие преимущества и недостатки распределенных приложений существуют на Ваш взгляд?
+5. Целесообразно ли в сложную распределенную систему внедрять параллельные вычисления? Приведите примеры, когда это действительно нужно, а когда нет.
+
+## Эссе
+
+1.Каждое приложение функционально выполняет ограниченный спектр задач, что позволяет системе быть модульной и легко адаптируемой к изменениям в требованиях или технологиях. Это также снижает общую сложность системы, поскольку отдельные компоненты могут быть разработаны, протестированы и развернуты независимо друг от друга.
+2.Системы оркестрации приложений были созданы для упрощения управления и координации распределенных систем. Они позволяют автоматизировать развертывание, масштабирование и мониторинг приложений, а также обеспечивают интеграцию различных сервисов и компонентов. В то же время, их использование может усложнить разработку и поддержку распределенных систем для менее опытных разработчиков, поскольку требует понимания и применения определенных инструментов и подходов.
+3.Очереди обработки сообщений нужны для асинхронной коммуникации между компонентами распределенных систем и обеспечения их стабильной работы. Сообщениями могут быть любые данные, которые требуют обработки или передачи между различными частями приложения.
+4.Распределенные приложения имеют преимущества, такие как масштабируемость, надежность и гибкость. Однако они также имеют и недостатки, такие как сложность в управлении и сопровождении, проблемы с согласованностью данных и необходимость в более сложной инфраструктуре.
+5.Внедрение параллельных вычислений в сложную распределенную систему может быть целесообразным, если система должна обрабатывать большое количество данных или выполнять множество операций одновременно. Это может ускорить процесс обработки и повысить производительность. Однако это также может увеличить сложность системы и потребовать дополнительных усилий для обеспечения ее стабильности и согласованности. Примеры, когда параллельные вычисления действительно нужны, включают обработку больших объемов данных, анализ в реальном времени и игры с интенсивной графикой. В то время как для систем, которые выполняют менее сложные и ресурсоемкие операции, параллельные вычисления могут не потребоваться.

+
+## Создание приложения
+
+Выбрал язык C#, Windows Forms.
+
+Приложение имеет три текстовых поля, в которых можно через пробел вносить элементы матрицы. В матрицы-множители значения можно сгенерировать внутри программы. Размерность можно регулировать от 2 до 1000 в специальном поле.  При необходимости можно очистить все матрицы. Также есть флажок выключения вывода значений матриц в текстовые поля, т.к. это занимает слишком много времени. Количество потоков в параллельном алгоритме регулируется в соответствующем поле. 
+
+Попробуем запустить обычный и паралелльный алгоритмы на матрицах 10х10 и зафиксировать результат выполнения по времени.
+
+![](pic/1.png)
+![](pic/2.png)
+
+
+## Бенчмарки
+
+Протестируем обычный и параллельный алгоритм матрицах 100х100, 300х300 и 500х500.
+Сверху отображен результат обычного алгоритма, снизу паралелльного.
+
+Матрицы 100х100
+
+![](pic/3.png)
+![](pic/4.png)
+
+Матрицы 300х300
+
+![](pic/5.png)
+![](pic/6.png)
+
+Матрицы 500х500
+
+![](pic/7.png)
+![](pic/8.png)
+
+
+Вывод: Параллельный алгоритм работает быстрее только при наличии большого количества операций и данных. Если элементов не так много, то обычный алгоритм справляется быстрее. Также была обнаружено оптимальное количество потоков для лучшей работы обработки матриц 500х500 - 4 потока.

+    Microsoft ResX Schema 
+
+    Version 2.0
+
+    The primary goals of this format is to allow a simple XML format
+    that is mostly human readable. The generation and parsing of the
+    various data types are done through the TypeConverter classes
+    associated with the data types.
+
+    Example:
+
+    ... ado.net/XML headers & schema ...
+    <resheader name="resmimetype">text/microsoft-resx</resheader>
+    <resheader name="version">2.0</resheader>
+    <resheader name="reader">System.Resources.ResXResourceReader, System.Windows.Forms, ...</resheader>
+    <resheader name="writer">System.Resources.ResXResourceWriter, System.Windows.Forms, ...</resheader>
+    <data name="Name1"><value>this is my long string</value><comment>this is a comment</comment></data>
+    <data name="Color1" type="System.Drawing.Color, System.Drawing"">Blue</data>
+    <data name="Bitmap1" mimetype="application/x-microsoft.net.object.binary.base64">
+        <value>[base64 mime encoded serialized .NET Framework object]</value>
+    </data>
+    <data name="Icon1" type="System.Drawing.Icon, System.Drawing" mimetype="application/x-microsoft.net.object.bytearray.base64">
+        <value>[base64 mime encoded string representing a byte array form of the .NET Framework object]</value>
+        <comment>This is a comment</comment>
+    </data>
+
+    There are any number of "resheader" rows that contain simple
+    name/value pairs.
+
+    Each data row contains a name, and value. The row also contains a
+    type or mimetype. Type corresponds to a .NET class that support
+    text/value conversion through the TypeConverter architecture.
+    Classes that don't support this are serialized and stored with the
+    mimetype set.
+
+    The mimetype is used for serialized objects, and tells the
+    ResXResourceReader how to depersist the object. This is currently not
+    extensible. For a given mimetype the value must be set accordingly:
+
+    Note - application/x-microsoft.net.object.binary.base64 is the format
+    that the ResXResourceWriter will generate, however the reader can
+    read any of the formats listed below.
+
+    mimetype: application/x-microsoft.net.object.binary.base64
+    value   : The object must be serialized with
+            : System.Runtime.Serialization.Formatters.Binary.BinaryFormatter
+            : and then encoded with base64 encoding.
+    
+    mimetype: application/x-microsoft.net.object.soap.base64
+    value   : The object must be serialized with
+            : System.Runtime.Serialization.Formatters.Soap.SoapFormatter
+            : and then encoded with base64 encoding.
+
+    mimetype: application/x-microsoft.net.object.bytearray.base64
+    value   : The object must be serialized into a byte array
+            : using a System.ComponentModel.TypeConverter
+            : and then encoded with base64 encoding.

+    Microsoft ResX Schema 
+
+    Version 2.0
+
+    The primary goals of this format is to allow a simple XML format
+    that is mostly human readable. The generation and parsing of the
+    various data types are done through the TypeConverter classes
+    associated with the data types.
+
+    Example:
+
+    ... ado.net/XML headers & schema ...
+    <resheader name="resmimetype">text/microsoft-resx</resheader>
+    <resheader name="version">2.0</resheader>
+    <resheader name="reader">System.Resources.ResXResourceReader, System.Windows.Forms, ...</resheader>
+    <resheader name="writer">System.Resources.ResXResourceWriter, System.Windows.Forms, ...</resheader>
+    <data name="Name1"><value>this is my long string</value><comment>this is a comment</comment></data>
+    <data name="Color1" type="System.Drawing.Color, System.Drawing"">Blue</data>
+    <data name="Bitmap1" mimetype="application/x-microsoft.net.object.binary.base64">
+        <value>[base64 mime encoded serialized .NET Framework object]</value>
+    </data>
+    <data name="Icon1" type="System.Drawing.Icon, System.Drawing" mimetype="application/x-microsoft.net.object.bytearray.base64">
+        <value>[base64 mime encoded string representing a byte array form of the .NET Framework object]</value>
+        <comment>This is a comment</comment>
+    </data>
+
+    There are any number of "resheader" rows that contain simple
+    name/value pairs.
+
+    Each data row contains a name, and value. The row also contains a
+    type or mimetype. Type corresponds to a .NET class that support
+    text/value conversion through the TypeConverter architecture.
+    Classes that don't support this are serialized and stored with the
+    mimetype set.
+
+    The mimetype is used for serialized objects, and tells the
+    ResXResourceReader how to depersist the object. This is currently not
+    extensible. For a given mimetype the value must be set accordingly:
+
+    Note - application/x-microsoft.net.object.binary.base64 is the format
+    that the ResXResourceWriter will generate, however the reader can
+    read any of the formats listed below.
+
+    mimetype: application/x-microsoft.net.object.binary.base64
+    value   : The object must be serialized with
+            : System.Runtime.Serialization.Formatters.Binary.BinaryFormatter
+            : and then encoded with base64 encoding.
+    
+    mimetype: application/x-microsoft.net.object.soap.base64
+    value   : The object must be serialized with
+            : System.Runtime.Serialization.Formatters.Soap.SoapFormatter
+            : and then encoded with base64 encoding.
+
+    mimetype: application/x-microsoft.net.object.bytearray.base64
+    value   : The object must be serialized into a byte array
+            : using a System.ComponentModel.TypeConverter
+            : and then encoded with base64 encoding.

+# Отчет по лабораторной работе №6
+
+Выполнил студент гр. ИСЭбд-41 Дунаев О.И.
+
+## Создание приложения
+
+Выбрал язык C#, Windows Forms.
+
+Приложение имеет поле ввода матрицы, в которое можно через пробел вносить элементы матрицы. При необходимости можно сгенерировать матрицу указав её размерность . При необходимости можно очистить матрицу и определитель. Количество потоков в параллельном алгоритме регулируется в соответствующем поле.  
+
+Попробуем запустить обычный и паралелльный алгоритмы на матрицах 3х3 и зафиксировать результат выполнения по времени.
+
+![](pic/1.png)
+![](pic/2.png)
+
+
+
+## Бенчмарки
+
+Протестируем обычный и параллельный алгоритм определение детерминанта на различной размерности матрицы. 
+
+В ходе экспериментов было установлено, что обработка матрицы размеров больше 12х12 занимает слишком много времени в обычном алгоритме, поэтому для тестирования возьмем матрицы 5х5, 8х8 и 11х11. 
+
+Сверху отображен результат обычного алгоритма, снизу паралелльного.
+
+Матрица 5х5
+
+![](pic/5x5№1.png)
+![](pic/5x5№2.png)
+
+Матрицы 8x8
+
+![](pic/8x8№1.png)
+![](pic/8x8№2.png)
+
+Матрицы 12х12
+
+![](pic/12x12№1.png)
+![](pic/12x12№2.png)
+
+Вывод: Параллельный алгоритм работает быстрее только при наличии большого количества операций. Если операций не так много, то обычный алгоритм справляется быстрее.

+## Создание приложений
+
+Создадим 2 приложения.
+Был выбран язык C# и технология .NET 5.
+
+Для создания обычных консольных приложений воспользуемся командами:
+
+```sh
+dotnet new console -o worker-1
+dotnet new console -o worker-2
+```
+
+Согласно варианту, программа 1 ищет в каталоге /var/data файл с наибольшим количеством строк и перекладывает его в /var/result/data.txt.
+
+[Исходный код программы worker-1](worker-1/Program.cs)
+
+Согласно варианту программа 2 должна искать набольшее число из файла /var/data/data.txt и сохраняет его вторую степень в /var/result/result.txt.
+
+[Исходный код программы worker-2](worker-2/Program.cs)
+
+Дополнительно создан файл [.gitignore](.gitignore) для того, чтобы не закоммитить в git ничего лишнего.
+
+## Настройка окружения
+
+Для связи двух приложений воспользуемся следующей схемой:
+
+1. Каталог `./data` должен быть примонтирован в каталог `/var/data` для программы 1.
+   Оттуда будут браться исходные данные.
+2. Каталог `./result-1` должен быть примонтирован в каталог `/var/result` для программы 2.
+   Туда будут складываться промежуточные данные.
+3. Каталог `./result-1` также должен быть примонтирован в каталог `/var/data` для программы 2.
+   Оттуда будут браться промежуточные результаты.
+4. Каталог `./result` должен быть примонтирован в каталог `/var/result` для программы 2.
+   Туда будут складывать результаты финальной обработки.
+
+Для каждой программы были созданы файлы Dockerfile ([программа 1](worker-1/Dockerfile), [программа 2](worker-2/Dockerfile)) с подробным описанием процесса сборки.
+
+Был создан файл [docker-compose.yml](docker-compose.yml), в котором указан манифест для запуска распределённого приложения.
+
+
+## Сборка и запуск
+
+1. В каталог `./data` помещены 3 файла с различными названиями и содержимым.
+
+![](scrins/1.png)
+
+На выходе программа должна записать данные из рандомного файла директории `/var/data`.
+
+![](scrins/5.png)
+![](scrins/3.png)
+![](scrins/4.png)
+
+2. Теперь, обрабатывая эти файлы:
+
+![](scrins/2.png)
+
+На выходе программа должна записать число 7921 в `./result` так как в файле c названием data.txt наибольшее число = 89.
+
+![](scrins/6.png)
+
+Для запуска приложения необходимо ввести команду `docker compose up --build`.
+Результат запуска после сборки:
+
+```
+[+] Running 2/1
+ ✔ Container lab_2-worker-1-1  Created                                                                                                                                                                     0.0s 
+ ✔ Container lab_2-worker-2-1  Created                                                                                                                                                                     0.0s 
+Attaching to lab_2-worker-1-1, lab_2-worker-2-1
+lab_2-worker-1-1  | Файл /var/data/data.txt успешно скопирован в /var/result/data.txt.
+lab_2-worker-1-1 exited with code 0
+lab_2-worker-2-1  | Квадрат наибольшего числа сохранено в файле: /var/result/result.txt
+lab_2-worker-2-1 exited with code 0
+```
+
+В результате в каталоге `./result` создался файл `result.txt` с содержимым `7921`, что соответствует входным данным.
+
+Изменение значений в файлах из каталога `./data` также изменяет содержимое в файлах из каталогов `./result-1` и `./result`.
