## Непрерывная архитектура
|
||||
|
||||
### 1. Architecture as Code
|
||||
|
||||
```yaml
|
||||
# Architecture Definition

|
||||
version: "1.0"

### 2. Architecture Evolution
|
||||
|
||||
```markdown
|
||||
# Процесс эволюции архитектуры
|
||||
|
||||
## 1. Мониторинг архитектуры
|
||||
- Отслеживание метрик качества
|
||||
- Анализ технического долга
|
||||
- Обратная связь от команды
|
||||
|
||||
## 2. Идентификация проблем
|
||||
- Производительность
|
||||
- Масштабируемость
|
||||
- Поддерживаемость
|
||||
- Безопасность
|
||||
|
||||
## 3. Планирование изменений
|
||||
- Приоритизация проблем
|
||||
- Разработка решений
|
||||
- Планирование миграции
|
||||
|
||||
## 4. Реализация изменений
|
||||
- Поэтапная миграция
|
||||
- Тестирование изменений
|
||||
- Мониторинг результатов
|
||||
```
|
||||
|
||||
## Инструменты управления архитектурой
|
||||
|
||||
### 1. Architecture Decision Records (ADR)
|
||||
|
||||
```markdown
|
||||
# ADR-001: Выбор базы данных для пользовательского сервиса
|
||||
|
||||
## Статус
|
||||
Принято
|
||||
|
||||
## Контекст
|
||||
Нужно выбрать базу данных для хранения пользовательских данных в новом микросервисе.
|
||||
|
||||
## Варианты
|
||||
1. PostgreSQL - реляционная БД
|
||||
2. MongoDB - документная БД
|
||||
3. DynamoDB - NoSQL БД
|
||||
|
||||
## Решение
|
||||
Выбрана PostgreSQL по следующим причинам:
|
||||
- ACID транзакции для критических данных
|
||||
- Зрелая экосистема и инструменты
|
||||
- Опыт команды с SQL
|
||||
- Хорошая производительность для наших объемов
|
||||
|
||||
## Последствия
|
||||
- Нужно спроектировать схему БД
|
||||
- Настроить репликацию для отказоустойчивости
|
||||
- Реализовать миграции данных
|
||||
```
|
||||
|
||||
### 2. Architecture Compliance
|
||||
|
||||
```yaml
|
||||
# Architecture Compliance Check
|
||||
compliance_check:
|
||||
rules:
|
||||
- name: "Microservice Communication"
|
||||
description: "Microservices must communicate only through APIs"
|
||||
check: "No direct database access between services"
|
||||
severity: "Error"
|
||||
|
||||
- name: "Security Headers"
|
||||
description: "All HTTP responses must include security headers"
|
||||
check: "X-Content-Type-Options, X-Frame-Options, X-XSS-Protection"
|
||||
severity: "Warning"
|
||||
|
||||
- name: "Logging Standards"
|
||||
description: "All services must use structured logging"
|
||||
check: "JSON format with correlation ID"
|
||||
severity: "Info"
|
||||
|
||||
enforcement:
|
||||
- "Pre-commit hooks"
|
||||
- "CI/CD pipeline checks"
|
||||
- "Architecture review process"
|
||||
```
|
||||
|
||||
### 3. Architecture Metrics
|
||||
|
||||
```yaml
|
||||
# Architecture Quality Metrics
|
||||
architecture_metrics:
|
||||
performance:
|
||||
- name: "Response Time"
|
||||
target: "< 200ms"
|
||||
measurement: "95th percentile"
|
||||
|
||||
