# Отчет по лабораторной работе №7
Выполнил студент гр. ИСЭбд-41 Дунаев О.И.
## 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.

# Отчет по лабораторной работе №3
Выполнил студент гр. ИСЭбд-41 Дунаев О.И.
## 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;
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-Real-IP $remote_addr;
proxy_set_header X-Forwarded-Proto $scheme;
proxy_set_header X-Forwarded-Prefix /worker-2;
}
}
```
Результат, после выполнения команды `docker-compose up`:

# Отчет по лабораторной работе №4
Выполнил студент гр. ИСЭбд-41 Дунаев О.И.
## Прохождение tutorial
Установил rabbitMQ server, erlang и зашел в брокер под гостем по http://localhost:15672/#/

Туториал 3:

![](scrins/emitlog.png)
![](scrins/receivelogs.png).
## 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.

# Отчет по лабораторной работе №8
Выполнил студент гр. ИСЭбд-41 Дунаев О.И.
## 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.

# Отчет по лабораторной работе №5
Выполнил студент гр. ИСЭбд-41 Дунаев О.И.
## 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`.
