# System Design
|
|
|
|
## Overview
|
|
|
|
GoodGo Microservices Platform is built using a microservices architecture pattern with the following principles:
|
|
|
|
- **Service Independence**: Each service has its own database and can be deployed independently
|
|
- **API Gateway**: Traefik handles routing, load balancing, and cross-cutting concerns
|
|
- **Shared Libraries**: Common functionality is extracted into shared packages
|
|
- **Infrastructure as Code**: All infrastructure configurations are versioned
|
|
- **Observability**: Full monitoring, logging, and tracing capabilities
|
|
|

## Components
|
|
|
|
### Frontend Layer
|
|
- **Web App**: Next.js application with App Router
|
|
- **Mobile App**: React Native application
|
|
|
|
### API Gateway
|
|
- **Traefik**: Reverse proxy, load balancer, SSL termination
|
|
|
|
### Services Layer
|
|
- **Auth Service**: Authentication and authorization
|
|
- **Future Services**: Payment, Order, Notification, etc.
|
|
|
|
### Infrastructure Layer
|
|
- **PostgreSQL**: Primary database
|
|
- **Redis**: Caching and session storage
|
|
- **Prometheus**: Metrics collection
|
|
- **Grafana**: Metrics visualization
|
|
- **Loki**: Log aggregation
|
|
|
|
## Communication Patterns
|
|
|
|
- **Synchronous**: HTTP/REST for request-response patterns
|
|
- **Asynchronous**: Message queues (future implementation)
|
|
- **Service Discovery**: Docker networking and Kubernetes DNS
|
|
|
|
## Data Management
|
|
|
|
- **Database per Service**: Each service owns its data
|
|
- **API Composition**: Services expose APIs for data access
|
|
- **Event Sourcing**: Future consideration for audit trails
|
|
|
|
## Security
|
|
|
|
- **Authentication**: JWT tokens with refresh token rotation
|
|
- **Authorization**: Role-based access control (RBAC)
|
|
- **Network Security**: TLS/SSL, rate limiting, CORS
|
|
- **Secrets Management**: Environment variables, Kubernetes secrets
