# Отчет по лабораторной работе №3
Выполнил студент Михайлов Юрий гр. ИСЭбд-41 .
## REST API, Gateway и синхронный обмен между микросервисами
## Создание микросервисов
1. С помощью команды `dotnet new web -n worker-1` в терминале создали первый микросервис.
2. Добавил решение `dotnet new sln`. Связал решение и проект командой `dotnet sln worker-1.sln add worker-1.csproj` повторил для 2-ого микросервиса.
3. Добавил библиотеку Swagger и OpenAi в проекты и запустил с помощью команды `dotnet run`.
Протестированный микросервис:
![](picture/1.png)
## Реализация синхронного обмена.
Реализован код, который вызывет сихронно данные из соседнего микросервиса.
```cs
app.MapGet("/Сities/", async () =>
{
var httpClient = new HttpClient();
var secondWorkerResponse = await httpClient.GetStringAsync("http://worker-1:8080/");
return secondWorkerResponse.ToArray();
})
.WithName("GetCountries")
.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 команды `docker-compose up`:
Docker desktop:

# Отчёт по лабораторной работе №1
Выполнил: студент гр. ИСЭбд-41 Михайлов Ю.С.
## Разворачивание сервиса moodle
Содержимое файла `docker-compose.yml` в папке moodle:
```yaml
version: '2'
#Контейнер Mariadb используется как сервер для запуска
services:
mariadb:
image: docker.io/bitnami/mariadb:11.0
environment:
- ALLOW_EMPTY_PASSWORD=yes
- MARIADB_USER=bn_moodle
- MARIADB_DATABASE=bitnami_moodle
- MARIADB_CHARACTER_SET=utf8mb4
- MARIADB_COLLATE=utf8mb4_unicode_ci
volumes:
- 'mariadb_data:/bitnami/mariadb'
#Контейнер moodle используется для запуска сервиса
moodle:
image: docker.io/bitnami/moodle:4.2
ports: #порт
- '80:8080'
- '443:8443'
environment:

volumes:

depends_on:
- mariadb
volumes:
mariadb_data:
driver: local
moodle_data:
driver: local
moodledata_data:
driver: local
```
Далее в командной строке разворачиваем сервис командой `docker-compose up`:
![](pic1.png)
Открываем Docker Desktop и проверяем, что контейнер сервера базы данных и moodle созданы и запущены:
![](pic2.png)
Переходим на http://localhost:80:
![](pic3.png)
## Разворачивание сервиса Redmine
Содержимое файла `docker-compose.yml` в папке Redmine:
```yaml
version: '3.1'
services:
#Контейнер образа Redmine
redmine:
image: redmine
restart: always
ports: #порт
- 8082:3000
environment:
REDMINE_DB_MYSQL: db
REDMINE_DB_PASSWORD: example
REDMINE_SECRET_KEY_BASE: supersecretkey
#Контейнер образа базы данных MySQL
db:
image: mysql:5.7
restart: always
environment: #название и пароль админа БД
MYSQL_ROOT_PASSWORD: example
MYSQL_DATABASE: redmine
```
Далее в командной строке разворачиваем сервис командой `docker-compose up`:
![](pic4.png)
В Docker Desktop проверяем, что контейнер сервера базы данных и Redmine созданы и запущены:
![](pic5.png)
Переходим на http://localhost:8082:

## Разворачивание сервиса Gitea
Содержимое файла `docker-compose.yml` в папке Gitea:
```yaml

external: false
#Контейнер образа Gitea для запуска сервиса

## Разработка демонстрационных приложений
Предметная область - оформление заявлений на стипендию в университете. Разработано три приложения согласно предметной области.
1. Publisher:
```
using System.Text;
using RabbitMQ.Client;
var factory = new ConnectionFactory { HostName = "localhost" };
using var connection = factory.CreateConnection();
using var channel = connection.CreateModel();
channel.ExchangeDeclare(exchange: "report", type: ExchangeType.Fanout);
Random rand = new Random();
foreach (var item in Enumerable.Range(0, 1000))
{
var message = rand.Next().ToString();
var body = Encoding.UTF8.GetBytes(message);
channel.BasicPublish(exchange: "report",
routingKey: string.Empty,
basicProperties: null,
body: body);
Console.WriteLine($" [x] Поступило заявление {message}");
await Task.Delay(500);
}
Console.WriteLine(" Press [enter] to exit.");
Console.ReadLine();
static string GetMessage(string[] args)
{
return ((args.Length > 0) ? string.Join(" ", args) : "info: Принято!");
}
```
2. Consumer 1:
```
using System.Text;
using RabbitMQ.Client;
using RabbitMQ.Client.Events;
var factory = new ConnectionFactory { HostName = "localhost" };
using var connection = factory.CreateConnection();
using var channel = connection.CreateModel();
channel.QueueDeclare(queue: "accepted");
channel.QueueBind(queue: "accepted",
exchange: "report",
routingKey: string.Empty);
Console.WriteLine(" [*] Waiting for messages.");
var consumer = new EventingBasicConsumer(channel);
consumer.Received += async (model, ea) =>
{
byte[] body = ea.Body.ToArray();
var message = Encoding.UTF8.GetString(body);
string outputText = $"Заявление принято к обработке {message}";
Console.WriteLine($" [x] Done. {outputText}");
channel.BasicAck(deliveryTag: ea.DeliveryTag, multiple: false);
};
channel.BasicConsume(queue: "accepted",
autoAck: false,
consumer: consumer);
Console.WriteLine(" Press [enter] to exit.");
Console.ReadLine();
```
3. Consumer 3:
```
using System.Text;
using RabbitMQ.Client;
using RabbitMQ.Client.Events;
var factory = new ConnectionFactory { HostName = "localhost" };
using var connection = factory.CreateConnection();
using var channel = connection.CreateModel();
Random rand = new Random();
string queueName = $"denied{rand.Next()}";
channel.QueueDeclare(queue: queueName);
channel.QueueBind(queue: queueName,
exchange: "report",
routingKey: string.Empty);
Console.WriteLine(" [*] Waiting for messages.");
var consumer = new EventingBasicConsumer(channel);
consumer.Received += async (model, ea) =>
{
byte[] body = ea.Body.ToArray();
var message = Encoding.UTF8.GetString(body);
int waitTime = rand.Next(20, 90);
Thread.Sleep(waitTime * 100);
string outputText = $"Заявление обработано {message} за {waitTime} минут";
Console.WriteLine($" [x] Done. {outputText}");
channel.BasicAck(deliveryTag: ea.DeliveryTag, multiple: false);
};
channel.BasicConsume(queue: queueName,
autoAck: false,
consumer: consumer);
Console.WriteLine(" Press [enter] to exit.");
Console.ReadLine();
```
## Результаты выполнения работы
Запуск каждой программы:
![](pic/11.PNG)
![](pic/12.PNG)
![](pic/13.PNG)
Результаты обработки:
![](pic/14.PNG)
![](pic/15.PNG)
Вывод: Consumer_2 нагружает меньше памяти, чем Consumer_1 и принимает сообщения гораздо быстрее, тем самым не позволяя очереди накапливать огромное количество сообщений

# Отчёт по лабораторной работе №5
Выполнил: студент гр. ИСЭбд-41 Михайлов Ю.С.
## Запуск приложения
Было выбрано консольное приложение, язык программирования - C#.
Перемножение матриц обычным алгоритмом:
```
public static int[][] MultiplySequential(int[][] matrixA, int[][] matrixB)
{
int rowsA = matrixA.Length;
int colsA = matrixA[0].Length;
int colsB = matrixB[0].Length;
int[][] result = new int[rowsA][];
for (int i = 0; i < rowsA; i++)
{
result[i] = new int[colsB];
for (int j = 0; j < colsB; j++)
{
for (int k = 0; k < colsA; k++)
{
result[i][j] += matrixA[i][k] * matrixB[k][j];
}
}
}
return result;
}
```
Перемножение матриц параллельным алгоритмом:
```
public static int[][] MultiplyParallel(int[][] matrixA, int[][] matrixB, int numThreads)
{
int rowsA = matrixA.Length;
int colsA = matrixA[0].Length;
int colsB = matrixB[0].Length;
int[][] result = new int[rowsA][];
Parallel.For(0, rowsA, new ParallelOptions { MaxDegreeOfParallelism = numThreads }, i =>
{
result[i] = new int[colsB];
for (int j = 0; j < colsB; j++)
{
for (int k = 0; k < colsA; k++)
{
result[i][j] += matrixA[i][k] * matrixB[k][j];
}
}
});
return result;
}
```
## Результаты
![](pic.PNG)
Вывод: если в матрице не слишком много элементов, обычный алгоритм работает быстрее. Параллельный алгоритм следует использовать для обработки большого количества данных. В сравнении с однопоточным алгоритмом, работа параллельного в несколько раз быстрее.
