# Aegis
_Multi-tenant API Gateway built on OpenResty_
[](https://github.com/aegis-gateway/aegis)
[](LICENSE)
[](docker-compose.yml)
## Overview
Aegis is an open-source, high-performance API gateway designed for multi-tenant applications. Built on OpenResty with enterprise-grade features including hierarchical tenant management, advanced rate limiting, and comprehensive observability.
## Performance
- Sub-2ms latency with OpenResty
- 100K+ requests per second per node
- Zero-downtime configuration changes
- Native multi-tenant architecture
## Quick Start
### Docker (Recommended)
```bash
# Clone the repository
git clone https://github.com/kanutocd/aegis.git
cd aegis
# Start the complete stack
docker-compose up -d
# Verify installation
./scripts/aegis gateway status
```
### Manual Installation
```bash
# Install dependencies
sudo apt-get update
sudo apt-get install openresty redis-server consul
# Install Ruby gems for admin interface
cd admin && bundle install
# Configure and start services
cd core && openresty -p . -c config/nginx.conf
cd admin && ruby lib/aegis_admin.rb
# Use the CLI
chmod +x scripts/aegis
./scripts/aegis gateway status
```
### First Steps
```bash
# Create your first tenant
./scripts/aegis tenant create --name "acme-corp" --tier premium
# Install plugins
./scripts/aegis plugin install --name rate-limit-advanced --version 2.0.0
# View metrics
./scripts/aegis gateway metrics
```
## Architecture Overview
Core components:
- **Multi-Tenant Core**: Hierarchical tenant support (Enterprise → Organization → Team → User)
- **Plugin System v2.0**: Hot reload with 12 lifecycle phases
- **Advanced Rate Limiting**: 4 algorithms with per-tenant limits
- **Security**: JWT, RBAC, mTLS support
- **CLI Management**: Complete gateway administration
- **Observability**: Prometheus metrics with Datadog integration
## Core Features
### Multi-Tenancy
- Hierarchical tenant structure: Enterprise → Organization → Team → User
- Three isolation levels: Strict, Shared, or Hybrid per service
- Automatic tenant detection from subdomains
- Per-tenant resource quotas and usage tracking
- Cross-tenant analytics for billing
### Plugin System v2.0
- Hot reload: Zero-downtime plugin updates
- 12 lifecycle phases for maximum flexibility
- Dependency management and automatic resolution
- Plugin templates for rapid development
```bash
# Create and install plugins instantly
./scripts/aegis plugin create my-custom-plugin
./scripts/aegis plugin install --name rate-limit-advanced --marketplace
./scripts/aegis plugin reload # Hot reload without restart
```
### Security
- Advanced JWT validation with hierarchical tenant support
- Role-based access control with Redis caching
- Rate limiting with 4 algorithms (Fixed Window, Sliding Window, Token Bucket, Leaky Bucket)
- Complete multi-tenant isolation and routing
### Observability & Analytics
- 20+ built-in Prometheus metrics with tenant-specific tracking
- Datadog integration for real-time metric streaming
- Per-tenant performance and usage analytics
- Plugin execution time monitoring
- Structured JSON logging with tenant context
### CLI Management
- Complete gateway deployment and configuration
- Hierarchical tenant management
- Plugin lifecycle management with hot reload
- Analytics export and reporting
```bash
# Gateway management
./scripts/aegis gateway status
./scripts/aegis gateway deploy --config production.yaml
# Tenant operations
./scripts/aegis tenant create --name customer-x --tier enterprise
./scripts/aegis tenant list
# Plugin ecosystem
./scripts/aegis plugin install --name security-suite
./scripts/aegis plugin create custom-auth
# Analytics and monitoring
./scripts/aegis analytics export --tenant customer-x --format csv
./scripts/aegis gateway metrics
```
