Load Balancer Strategy

ALB + NGINX Ingress Controller (기본, 권장)
─────────────────────────────────────
- L7 로드밸런싱 (HTTP/HTTPS/gRPC)
- CORS: Ingress annotation으로 처리 (앱 코드 불필요)
- Path-based routing (/api/auth/*, /api/users/*)
- AWS Certificate Manager (ACM) TLS 연동
- WAF 연동 가능

NLB (특수 케이스만)
─────────────────────────────────────
- L4 로드밸런싱 (TCP/UDP)
- 극도의 저지연 필요 시 (< 1ms)
- WebSocket/gRPC 전용 서비스
- CORS 처리 불가 → 앱단에서 직접 처리 필요

Core Patterns

Repository Pattern

python

# domain/repositories/user_repository.py (interface)
from abc import ABC, abstractmethod

class UserRepository(ABC):
    @abstractmethod
    async def find_by_id(self, id: str) -> User | None:
        pass

    @abstractmethod
    async def save(self, user: User) -> User:
        pass

# infrastructure/repositories/user_repository_impl.py (implementation)
class UserRepositoryImpl(UserRepository):
    def __init__(self, db: AsyncSession):
        self.db = db

    async def find_by_id(self, id: str) -> User | None:
        result = await self.db.execute(
            select(UserModel).where(UserModel.id == id)
        )
        return result.scalar_one_or_none()

Inter-service Communication

python

# Synchronous (Internal API)
async def get_user_info(user_id: str) -> dict:
    async with httpx.AsyncClient() as client:
        response = await client.get(
            f"{USER_SERVICE_URL}/internal/users/{user_id}",
            headers={"X-Internal-Token": INTERNAL_TOKEN}
        )
        return response.json()

# Asynchronous (message queue)
await message_queue.publish(
    topic="user.created",
    message={"user_id": user.id, "email": user.email}
)

Terraform Module

hcl

# modules/eks/main.tf
resource "aws_eks_cluster" "this" {
  name     = "${var.environment}-${var.project_name}-eks"
  role_arn = aws_iam_role.cluster.arn
  version  = var.kubernetes_version

  vpc_config {
    subnet_ids = var.subnet_ids
  }

  tags = merge(var.tags, {
    Environment = var.environment
  })
}

Kubernetes Deployment

yaml

# k8s/base/backend/deployment.yaml
apiVersion: apps/v1
kind: Deployment
metadata:
  name: user-service
spec:
  replicas: 2
  template:
    spec:
      containers:
        - name: user-service
          image: ${ECR_REGISTRY}/user-service:${TAG}
          resources:
            requests:
              cpu: "100m"
              memory: "256Mi"
            limits:
              cpu: "500m"
              memory: "512Mi"
          livenessProbe:
            httpGet:
              path: /health
              port: 8000

Environment Configuration

Environment	Infrastructure	Deployment Method
Local	Docker Compose	Manual
Staging	EKS	ArgoCD Auto Sync
Production	EKS	ArgoCD Manual Sync

Security Rules

✅ Allowed
- Retrieve secrets from Secrets Manager
- IAM role-based access
- VPC internal communication
- mTLS (inter-service)

❌ Prohibited
- Hardcoded secrets
- DB in public subnet
- Using root account
- Excessive IAM permissions

CI/CD Pipeline

Push to feature/*
    ↓
GitHub Actions (CI)
    - Lint
    - Test
    - Build Docker image
    - Push to ECR
    ↓
PR to staging
    ↓
ArgoCD Auto Sync (Staging)
    ↓
PR to main
    ↓
ArgoCD Manual Sync (Production)

SoR Priority

1st Priority: Codebase
  - scripts/init-db.sql (source of truth for DB schema)
  - services/{service}/app/ (each service implementation)

2nd Priority: CLAUDE.md / Convention docs
  - services/CLAUDE.md
  - frontend/CLAUDE.md
  - infra/CLAUDE.md

3rd Priority: docs/ design documents
  - For understanding design intent
  - If different from code, code is correct

AI Native Development

3 Core Principles

Document-First Design: Write design docs BEFORE code
Monorepo Context Control: All code in one repo for AI context
PR-Based Collaboration: Every change through PR

10-Day Development Pattern

Day	Focus	Output
1	Architecture	Market analysis + System architecture
2-3	Core	Auth, User + Business services
4-5	UX	PO feedback → Documentation → Implementation
6-7	QA	Zero Script QA + bug fixes
8	Infra	Terraform + GitOps
9-10	Production	Security review + Deployment

Monorepo Benefits for AI

Mono-repo:
└─ project/
    ├─ frontend/ ──────┐
    ├─ services/ ──────┤  AI reads completely
    ├─ infra/ ─────────┤  Context unified
    └─ packages/ ──────┘

✅ AI understands full context
✅ Single source of truth for types
✅ Atomic commits across layers
✅ Consistent patterns enforced

CLAUDE.md Hierarchy

project/
├── CLAUDE.md           # Project-wide context
├── frontend/CLAUDE.md  # Frontend conventions
├── services/CLAUDE.md  # Backend conventions
└── infra/CLAUDE.md     # Infra conventions

Rule: Area-specific CLAUDE.md overrides project-level rules

bkit Features for Enterprise Level (v1.5.1)

Output Style: bkit-enterprise (Recommended)

For CTO-level architecture perspectives, activate the enterprise style:

/output-style bkit-enterprise

This provides:

Architecture tradeoff analysis tables (Option/Pros/Cons/Recommendation)
Performance, security, and scalability perspectives for every decision
Cost impact estimates for infrastructure changes
Deployment strategy recommendations (Blue/Green, Canary, Rolling)
SOLID principles and Clean Architecture compliance checks

Agent Teams (4 Teammates)

Enterprise projects support full Agent Teams for parallel PDCA execution:

Role	Agents	PDCA Phases
architect	enterprise-expert, infra-architect	Design
developer	bkend-expert	Do, Act
qa	qa-monitor, gap-detector	Check
reviewer	code-analyzer, design-validator	Check, Act

To enable:

Set environment: CLAUDE_CODE_EXPERIMENTAL_AGENT_TEAMS=1
Start team mode: /pdca team {feature}
Monitor progress: /pdca team status

Agent Memory (Auto-Active)

All bkit agents automatically remember project context across sessions. Enterprise agents use project scope memory, ensuring architecture decisions and infrastructure patterns persist across development sessions.
