+# Site11 Platform Architecture
+
+## Executive Summary
+
+Site11 is a **large-scale, AI-powered content generation and aggregation platform** built on a microservices architecture. The platform automatically collects, processes, generates, and distributes multi-language content across various domains including news, entertainment, technology, and regional content for multiple countries.
+
+### Key Capabilities

+```
+
+### Security Measures
+- **JWT-based authentication**: Stateless token authentication
+- **Service-to-service auth**: Internal service tokens
+- **Rate limiting**: API Gateway level throttling
+- **CORS configuration**: Controlled cross-origin access
+- **Environment variables**: Sensitive data in `.env` files
+- **Network isolation**: Services communicate within Docker/K8s network
+
+## Monitoring & Observability
+
+### 1. Health Checks
+Every service implements health endpoints:
+```python
+GET /health
+Response: {"status": "healthy", "service": "service-name"}
+```
+
+### 2. Monitoring Stack
+- **Pipeline Monitor**: Real-time pipeline status (Port 8100)
+- **Console Dashboard**: Service health overview
+- **Redis Queue Monitoring**: Queue depth and processing rates
+- **MongoDB Metrics**: Database performance metrics
+
+### 3. Logging Strategy
+- Centralized logging with structured JSON format
+- Log levels: DEBUG, INFO, WARNING, ERROR
+- Correlation IDs for distributed tracing
+
+## Scalability & Performance
+
+### Horizontal Scaling
+- **Stateless services**: Easy horizontal scaling
+- **Load balancing**: Kubernetes service mesh
+- **Auto-scaling**: Based on CPU/memory metrics
+
+### Performance Optimizations
+- **Redis caching**: Reduces database load
+- **Async processing**: FastAPI async endpoints
+- **Batch processing**: Pipeline processes in batches
+- **Connection pooling**: Database connection reuse
+- **CDN ready**: Static content delivery
+
+### Resource Management
+```yaml
+Resources per Service:
+- CPU: 100m - 500m (request), 1000m (limit)
+- Memory: 128Mi - 512Mi (request), 1Gi (limit)
+- Storage: 1Gi - 10Gi PVC for data services
+```
+
+## Development Workflow
+
+### 1. Local Development
+```bash
+# Start all services
+docker-compose up -d
+
+# Start specific services
+docker-compose up -d console mongodb redis
+
+# View logs
+docker-compose logs -f [service-name]
+
+# Rebuild after changes
+docker-compose build [service-name]
+docker-compose up -d [service-name]
+```
+
+### 2. Testing
+```bash
+# Run unit tests
+docker-compose exec [service-name] pytest
+
+# Integration tests
+docker-compose exec [service-name] pytest tests/integration
+
+# Load testing
+docker-compose exec [service-name] locust
+```
+
+### 3. Deployment
+```bash
+# Development
+./deploy-local.sh
+
+# Staging (Kind)
+./deploy-kind.sh
+
+# Production (Kubernetes)
+./deploy-k8s.sh
+
+# Docker Hub
+./deploy-dockerhub.sh
+```
+
+## Key Design Decisions
+
+### 1. Microservices over Monolith
+- **Reasoning**: Independent scaling, technology diversity, fault isolation
+- **Trade-off**: Increased complexity, network overhead
+
+### 2. MongoDB as Primary Database
+- **Reasoning**: Flexible schema for diverse content types
+- **Trade-off**: Eventual consistency, complex queries
+
+### 3. Event-Driven with Kafka
+- **Reasoning**: Decoupling, scalability, real-time processing
+- **Trade-off**: Operational complexity, debugging challenges
+
+### 4. Python/FastAPI for Backend
+- **Reasoning**: Async support, fast development, AI library ecosystem
+- **Trade-off**: GIL limitations, performance vs compiled languages
+
+### 5. Container-First Approach
+- **Reasoning**: Consistent environments, easy deployment, cloud-native
+- **Trade-off**: Resource overhead, container management
+
+## Performance Metrics
+
+### Current Capacity (Single Instance)
+- **Content Generation**: 1000+ articles/day
+- **Translation Throughput**: 8 languages simultaneously
+- **API Response Time**: <100ms p50, <500ms p99
+- **Queue Processing**: 100+ jobs/minute
+- **Storage**: Scalable to TBs with MinIO
+
+### Scaling Potential
+- **Horizontal**: Each service can scale to 10+ replicas
+- **Vertical**: Services can use up to 4GB RAM, 4 CPUs
+- **Geographic**: Multi-region deployment ready
+
+## Future Roadmap
+
+### Phase 1: Current State ✅
+- Core microservices architecture
+- Automated content pipeline
+- Multi-language support
+- Basic monitoring
+
+### Phase 2: Enhanced Observability (Q1 2025)
