+
+## 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.

+
+## 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

+
+Матрицы 300х300

+![](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.

+    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.

+# Отчёт по лабораторной работе №2
+
+Выполнил: студентка гр. ИСЭбд-41 Горбылева Антонина 
+
+Вариант программы 1 (вариант 4): Формирует файл /var/result/data.txt так, что каждая строка файла - количество символов в именах файлов из каталога /var/data.
+
+Вариант программы 2 (вариант 2): Ищет наименьшее число из файла /var/data/data.txt и сохраняет его третью степень в /var/result/result.txt.
+
+## Создание приложений
+
+Создадим 2 приложения.
+Был выбран язык C# и технология .NET 7.
+
+Для создания обычных консольных приложений воспользуемся командами:
+
+dotnet new console -o worker-1
+dotnet new console -o worker-2
+
+Согласно варианту программа 1 должна брать все файлы из папки `/var/data`, и записывать длины имен файлов в `/var/result/data.txt`.
+
+[Исходный текст программы worker-1](worker-1/Program.cs)
+
+Согласно варианту программа 2 должна найти наименьшее число из файла `/var/data/data.txt` и сохранить его третью степень в `/var/result/result.txt`.
+
+[Исходный текст 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.
+
+Дополнительно был создан файл [.dockerignore](.dockerignore) и дополнен [.gitignore](.gitignore), чтобы исключить для сборки и коммита всё лишнее.
+
+## Сборка и запуск
+
+В каталог ./data помещены 3 файла.
+3 файла с общим количеством символов в названии 12
+
+Для запуска приложения необходимо ввести команду docker compose up ---build.
+
+Результат запуска после сборки:
+
+[+] Running 2/0
+ - Container lab_2-worker-1-1  Created
+ - Container lab_2-worker-2-1  Created
+Attaching to lab_2-worker-1-1, lab_2-worker-2-1
+lab_2-worker-1-1  | Начало обработки файла /var/data/another data.txt
+lab_2-worker-1-1  | Начало обработки файла /var/data/data.txt
+lab_2-worker-1-1 exited with code 0
+lab_2-worker-2-1  | Чисел для обработки: 8
+lab_2-worker-2-1 exited with code 0
+
+В результате в каталоге ./result создался файл result.txt с содержимым 12, что соответствует входным данным.
+
+В результате в каталоге `./result` создался файл `result.txt` с содержимым `1728`, что соответствует входным данным, так как наименьшим числом в нашем случае является `12`.

+# Отчёт по лабораторной работе №3
+
+Выполнила: студентка группы ИСЭбд-41 Горбылева Антонина Игоревна
+Используемые сущности: Автомобили - Car, марка автомобиля - Marka, модель - model, номер - number
+
+## REST API, Gateway и синхронный обмен между микросервисами
+## Создание микросервисов
+
+Команда `dotnet new web -n worker-1` создает в терминале микросервис worker-1.
+
+Команда `dotnet new sln`для создания решения для проекта. 
+Команда `dotnet sln worker-1.sln add worker-1.csproj`связывает созданное решение с проектом.
+
+Аналогично, создаем второй микросервис и добавляем оба проекта в единое решение.
+
+Команда `dotnet run` для запуска проекта.
+
+Скриншоты API приложений:
+
+![](picture/sworker-1.png) 
+![](picture/sworker-2.png)
+
+## Реализация синхронного обмена
+
+Реализован механизм синхронного обмена сообщениями между микросервисами.
+
+```cs
+app.MapGet("/Company/", async () =>
+{

+    var secondWorkerResponse = await httpClient.GetStringAsync("http://worker-1:8080/");
+
+    return secondWorkerResponse.ToArray();
+})
+.WithName("GetRequests")

+# Отчёт по лабораторной работе №3
+
+Выполнила: студентка гр. ИСЭбд-41 Никифорова Татьяна Сергеевна.
+
+## REST API, Gateway и синхронный обмен между микросервисами
+## Создание микросервисов
+
+Использовала команду `dotnet new web -n worker-1` в терминале для создания моего первого микросервиса.
+
+Далее, с помощью команды `dotnet new sln`, создала решение для проекта. Затем использовала команду `dotnet sln worker-1.sln add worker-1.csproj`, чтобы связать созданное решение с проектом.
+
+Повторила те же действия для второго микросервиса, добавила оба проекта в единое решение.
+
+Добавил библиотеку Swagger и OpenAi в проекты и запустил с помощью команды `dotnet run`".
+
+Скриншоты API приложений:

+
+## Реализация синхронного обмена
+
+Реализовала механизм синхронного обмена сообщениями между микросервисами.
+
+```cs
+app.MapGet("/Authors/", async () =>
+{
+    var httpClient = new HttpClient();
+    var secondWorkerResponse = await httpClient.GetStringAsync("http://worker-1:8080/");
+
+    return secondWorkerResponse.ToArray();
+})
+.WithName("GetRequests")
+.WithOpenApi();
+```
+
+## Реализация gateway при помощи nginx
+
+Реализовала шлюз на основе прозрачного прокси-сервера nginx.
+
+```conf
+server {
+    listen       8080;

+# Отчет по лабораторной работе №3
+
+Выполнила студентка гр. ИСЭбд-41 Гренадерова А.А.
+
+## REST API, Gateway и синхронный обмен между микросервисами
+
+## Создание микросервисов
+
+1. С помощью команды `dotnet new web -n worker-1` в терминале создала первый микросервис
+2. Добавила решение командой  `dotnet new sln`
+3. Связала решение и проект командой `dotnet sln worker-1.sln add worker-1.csproj`
+4. Повторила действие для второго микросервиса
+5. Добавила библиотеку Swagger и OpenAi в проекты и запустила с помощью команды `dotnet run`
+
+Скриншот протестированного микросервиса:
+![](screens/1.png) 
+
+## Реализация синхронного обмена
+
+Реализовала код, который вызывает сихронно данные из соседнего микросервиса.
+
+```cs
+//worker-2
+app.MapGet("/Houses/", async () =>
+{
+    var httpClient = new HttpClient();
+    var secondWorkerResponse = await httpClient.GetStringAsync("http://worker-1:8080/");
+
+    return secondWorkerResponse.ToArray();
+})
+.WithName("GetStreets")
+.WithOpenApi();
+```
+
+## Реализация gateway при помощи nginx
+
+Добавила 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;
+        proxy_set_header X-Real-IP $remote_addr;
+        proxy_set_header X-Forwarded-Proto $scheme;
+        proxy_set_header X-Forwarded-Prefix /worker-1;
+    }
+
+    location /worker-2/ {
+        proxy_pass       http://worker-2:8080/;
+        proxy_set_header Host      $host;

+        proxy_set_header X-Forwarded-Prefix /worker-2;
+    }
+}
+
+```
+
