-# Современные технологии разработки программного обеспечения
-[Таблица с успеваемостью](https://docs.google.com/spreadsheets/d/1an43o-iqlq4V_kDtkr_y7DC221hY9qdhGPrpII27sH8/edit?usp=sharing)
+# Облачная разработка — Сервис генерации данных сотрудников
-## Задание
-### Цель
-Реализация проекта микросервисного бекенда.
+## Описание
-### Задачи
-* Реализация межсервисной коммуникации,
-* Изучение работы с брокерами сообщений,
-* Изучение архитектурных паттернов,
-* Изучение работы со средствами оркестрации на примере .NET Aspire,
-* Повторение основ работы с системами контроля версий,
-* Интеграционное тестирование.
+Микросервисное приложение для генерации данных сотрудников компании с кэшированием и балансировкой нагрузки. Оркестрация осуществляется при помощи .NET Aspire.
-### Лабораторные работы
-
-1. «Кэширование» - Реализация сервиса генерации контрактов, кэширование его ответов
-
-
-В рамках первой лабораторной работы необходимо:
-* Реализовать сервис генерации контрактов на основе Bogus,
-* Реализовать кеширование при помощи IDistributedCache и Redis,
-* Реализовать структурное логирование сервиса генерации,
-* Настроить оркестрацию Aspire.
-
-
-
-2. «Балансировка нагрузки» - Реализация апи гейтвея, настройка его работы
-
-
-В рамках второй лабораторной работы необходимо:
-* Настроить оркестрацию на запуск нескольких реплик сервиса генерации,
-* Реализовать апи гейтвей на основе Ocelot,
-* Имплементировать алгоритм балансировки нагрузки согласно варианту.
+## Лабораторная работа №1 — Кэширование
-
-
-
-3. «Интеграционное тестирование» - Реализация файлового сервиса и объектного хранилища, интеграционное тестирование бекенда
-
+### Что реализовано
-В рамках третьей лабораторной работы необходимо:
-* Добавить в оркестрацию объектное хранилище,
-* Реализовать файловый сервис, сериализующий сгенерированные данные в файлы и сохраняющий их в объектном хранилище,
-* Реализовать отправку генерируемых данных в файловый сервис посредством брокера,
-* Реализовать интеграционные тесты, проверяющие корректность работы всех сервисов бекенда вместе.
+- **Сервис генерации сотрудников** (`EmployeeApp.Api`) на основе библиотеки Bogus
+- **Сущность `Employee`** с 10 полями: идентификатор, ФИО, должность, отдел, дата приёма, оклад, электронная почта, номер телефона, индикатор увольнения, дата увольнения
+- **Генерация данных** с учётом пола (ФИО, отчество, фамилия), корреляции оклада с суффиксом должности, формата телефона `+7(***)***-**-**`
+- **Кэширование** ответов через `IDistributedCache` и Redis
+- **Структурное логирование** с помощью `ILogger` (логирование попаданий/промахов кэша, ошибок)
+- **Оркестрация** через .NET Aspire (AppHost поднимает Redis, API и Redis Commander)
+- **CORS** настроен для приёма запросов от клиента
-
-
-
-4. (Опционально) «Переход на облачную инфраструктуру» - Перенос бекенда в Yandex Cloud
-
-
-В рамках четвертой лабораторной работы необходимо перенестиервисы на облако все ранее разработанные сервисы:
-* Клиент - в хостинг через отдельный бакет Object Storage,
-* Сервис генерации - в Cloud Function,
-* Апи гейтвей - в Serverless Integration как API Gateway,
-* Брокер сообщений - в Message Queue,
-* Файловый сервис - в Cloud Function,
-* Объектное хранилище - в отдельный бакет Object Storage,
+### Технологии
-
-
+- .NET 8, Minimal API
+- Bogus — генерация данных
+- Redis — распределённый кэш
+- .NET Aspire — оркестрация
-## Задание. Общая часть
-**Обязательно**:
-* Реализация серверной части на [.NET 8](https://learn.microsoft.com/ru-ru/dotnet/core/whats-new/dotnet-8/overview).
-* Оркестрация проектов при помощи [.NET Aspire](https://learn.microsoft.com/ru-ru/dotnet/aspire/get-started/aspire-overview).
-* Реализация сервиса генерации данных при помощи [Bogus](https://github.com/bchavez/Bogus).
-* Реализация тестов с использованием [xUnit](https://xunit.net/?tabs=cs).
-* Создание минимальной документации к проекту: страница на GitHub с информацией о задании, скриншоты приложения и прочая информация.
+## Лабораторная работа №2 — Балансировка нагрузки
-**Факультативно**:
-* Перенос бекенда на облачную инфраструктуру Yandex Cloud
+### Что реализовано
-Внимательно прочитайте [дискуссии](https://github.com/itsecd/cloud-development/discussions/1) о том, как работает автоматическое распределение на ревью.
-Сразу корректно называйте свои pr, чтобы они попали на ревью нужному преподавателю.
+- **API Gateway** на основе Ocelot с маршрутизацией запросов к бэкенду
+- **5 реплик** сервиса `EmployeeApp.Api`, создаваемых в цикле через AppHost
+- **Кастомный балансировщик нагрузки Query Based** — маршрутизация на основе параметра `id` из query string: `index = id % количество_реплик`
+- **CORS** на Gateway настроен на приём только GET-запросов от клиента
+- Gateway скрывает пути бэкенда через `UpstreamPathTemplate`
-По итогу работы в семестре должна получиться следующая информационная система:
-
-C4 диаграмма
-
-
-
-## Варианты заданий
-Номер варианта задания присваивается в начале семестра. Изменить его нельзя. Каждый вариант имеет уникальную комбинацию из предметной области, базы данных и технологии для общения сервиса генерации данных и сервера апи.
-
-[Список вариантов](https://docs.google.com/document/d/1WGmLYwffTTaAj4TgFCk5bUyW3XKbFMiBm-DHZrfFWr4/edit?usp=sharing)

-
-## Схема сдачи
-
-На каждую из лабораторных работ необходимо сделать отдельный [Pull Request (PR)](https://docs.github.com/en/pull-requests).
-
-Общая схема:
-1. Сделать форк данного репозитория
-2. Выполнить задание
-3. Сделать PR в данный репозиторий
-4. Исправить замечания после code review
-5. Получить approve
-
-## Критерии оценивания
-
-Конкурентный принцип.
-Так как задания в первой лабораторной будут повторяться между студентами, то выделяются следующие показатели для оценки:
-1. Скорость разработки
-2. Качество разработки
