## Overview
This is a production-ready Telecom-as-a-Service platform that enables developers to programmatically provision and manage cellular connectivity through a clean API. The platform implements 3GPP standards using modern open-source technologies.
The Telecom-as-a-Service (TaaS) Platform is a comprehensive, sovereign cellular connectivity solution that enables organizations to deploy and manage their own private 5G/LTE networks. This full-stack platform provides end-to-end capabilities from core network integration to subscriber management, charging, and developer APIs.
### What It Does
The TaaS Platform allows enterprises, telecom operators, and system integrators to:
- **Deploy Private Cellular Networks**: Set up and manage private 5G/LTE networks with full control over data sovereignty and security
- **Manage Subscribers**: Provision, authenticate, and manage cellular subscribers with role-based access control
- **Real-time Charging**: Implement flexible credit control and billing with real-time usage monitoring
- **Developer APIs**: Expose cellular network capabilities through REST and GraphQL APIs for custom application development
- **Network Orchestration**: Automate network operations, scaling, and health monitoring across distributed infrastructure
- **Service Discovery**: Enable dynamic service registration and discovery for microservices architecture
### Architecture
The platform is built as a microservices architecture with the following core components:
**Core Network Services:**
- **API Server**: Central BSS (Business Support System) API providing authentication, subscriber management, automation, and plugin system
- **Carrier Connector**: ES2+ interface for eSIM profile management and carrier integration
- **Charging Engine**: Real-time credit control, usage tracking, and billing with Redis-backed rate limiting
- **Packet Gateway**: High-performance eBPF-based packet processing for network traffic routing and QoS enforcement
**Supporting Services:**
- **Service Discovery (Consul)**: Dynamic service registration and health checking
- **Message Queue (RabbitMQ)**: Asynchronous event-driven communication between services
- **Redis**: Distributed caching, rate limiting, and session management
- **PostgreSQL**: Persistent data storage for subscribers, automations, and configuration
- **Vault**: Secure secret management for sensitive credentials and keys
**Developer Tools:**
- **CLI**: Command-line interface for service orchestration, configuration, and health checks
- **Web Dashboard**: Next.js-based management interface for network operations
- **TypeScript SDK**: Client library for integrating with TaaS APIs
- **Kubernetes Operators**: Custom resources for deploying and managing TaaS services
### Key Features
**Sovereignty & Security:**
- Full data sovereignty with on-premise deployment
- End-to-end encryption for subscriber data
- Role-based access control (RBAC) with fine-grained permissions
- Vault-based secret management for credential security
**Performance & Scalability:**
- eBPF-accelerated packet processing for line-rate throughput
- Redis-backed distributed rate limiting and caching
- Horizontal scaling with Kubernetes orchestration
- Circuit breakers and retry logic for external service resilience
**Developer Experience:**
- REST and GraphQL APIs with comprehensive documentation
- TypeScript SDK for type-safe client integration
- Plugin system for extending platform capabilities
- Automation framework for network operations
**Operations:**
- Real-time health monitoring with Prometheus integration
- Automated scaling and service discovery
- Centralized logging with structured logs
- Chaos engineering capabilities for testing resilience
**Technology Stack:**
**Core Languages & Runtimes:**
- **Go 1.26**: Core network integration, BSS API, carrier connector
- **Rust 1.94**: eBPF packet gateway, real-time charging engine
- **TypeScript/Next.js**: Developer dashboard and SDK
- **free5GC**: Open-source 5G core network
- **MongoDB**: Subscriber data and authentication
- **Redis**: Real-time credit control
- **eBPF/Aya**: High-performance packet processing
## Quick Start
**Databases:**
- **PostgreSQL**: Primary database for subscribers, automations, plugins, and configuration
- **Redis**: Real-time credit control, caching, and rate limiting
- **MongoDB**: Used exclusively by free5GC 5G core network for UDR/UDM subscription data and authentication
**5G Core Network:**
- **free5GC**: Open-source 5G core network (AMF, SMF, UDM, UDR, etc.)
**Infrastructure & Orchestration:**
- **Kubernetes**: Container orchestration and deployment
- **Helm**: Package management for Kubernetes deployments
- **Istio**: Service mesh for traffic management and security
- **eBPF/Aya**: High-performance packet processing in kernel space
**Message Queuing & Service Discovery:**
- **RabbitMQ**: Asynchronous message queue for event-driven communication
- **Consul**: Service discovery, health checking, and configuration
**Security & Secrets:**
- **Vault**: Secure secret management for credentials and keys
- **cert-manager**: Automated TLS certificate management
**Monitoring & Observability:**
- **Prometheus**: Metrics collection and alerting
- **Grafana**: Visualization dashboards for metrics
- **ELK Stack**: Elasticsearch, Logstash, Kibana for centralized logging
