+# 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 X-Forwarded-Prefix /worker-2;
+    }
+}

+## 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.

+## 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`.

+# 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 X-Forwarded-Proto $scheme;
+        proxy_set_header X-Forwarded-Prefix /worker-2;
+    }
+}
+```
+Результат после команды `docker-compose up`:
