Infrastructure Setup

This guide covers the essential infrastructure components and configurations needed to deploy Authlete in production environments.

​
Prerequisites

Before setting up your Authlete infrastructure, ensure you have:
  • Authlete Account - Active service subscription
  • Domain Configuration - Valid domain for your authorization server
  • SSL/TLS Certificates - Valid certificates for HTTPS endpoints
  • DNS Configuration - Proper DNS records for your domain

​
Core Infrastructure Components

​
1. Authorization Server

The authorization server is the core component that handles OAuth 2.0 and OpenID Connect flows. Key Requirements:
  • High availability (99.9% uptime)
  • Load balancing for traffic distribution
  • SSL/TLS termination
  • Rate limiting and DDoS protection

​
2. Token Endpoint

Secure endpoint for token issuance and refresh operations. Configuration: 
endpoints:
token: "https://auth.yourdomain.com/oauth/token"
introspection: "https://auth.yourdomain.com/oauth/introspect"
revocation: "https://auth.yourdomain.com/oauth/revoke"

​
3. UserInfo Endpoint

Provides user information for OpenID Connect implementations. Configuration: 
endpoints:
userinfo: "https://auth.yourdomain.com/oauth/userinfo"
jwks: "https://auth.yourdomain.com/.well-known/jwks.json"

​
Deployment Options

​
Cloud Deployment

Recommended Cloud Providers:
  • AWS (Amazon Web Services)
  • Google Cloud Platform
  • Microsoft Azure
  • DigitalOcean
Key Considerations:
  • Auto-scaling capabilities
  • Global CDN integration
  • Managed database services
  • Security and compliance features

​
On-Premises Deployment

For organizations requiring on-premises deployment: Requirements:
  • Container orchestration (Kubernetes/Docker Swarm)
  • Load balancer configuration
  • Database setup (PostgreSQL/MySQL)
  • Monitoring and logging infrastructure

​
Security Configuration

​
SSL/TLS Setup

  1. Certificate Management
    • Use Let’s Encrypt for free certificates
    • Implement certificate auto-renewal
    • Configure HSTS headers
  2. Cipher Suites
    • Use strong encryption algorithms
    • Disable weak protocols (TLS 1.0, 1.1)
    • Implement perfect forward secrecy

​
Network Security

  • Firewall Rules - Restrict access to necessary ports only
  • VPC Configuration - Isolate services in private subnets
  • WAF Integration - Web Application Firewall for additional protection

​
Database Configuration

​
Primary Database

Requirements:
  • High availability setup
  • Automated backups
  • Encryption at rest
  • Connection pooling
Recommended Setup: 
database:
type: "postgresql"
version: "13+"
replicas: 3
backup: "daily"
encryption: "enabled"

​
Caching Layer

Implement Redis for session and token caching: 
cache:
  type: "redis"
  cluster: "enabled"
  persistence: "aof"
  memory: "8gb"

​
Monitoring and Alerting

​
Key Metrics to Monitor

  • Performance Metrics
    • Response times
    • Throughput (requests/second)
    • Error rates
    • Database connection pools
  • Security Metrics
    • Failed authentication attempts
    • Suspicious activity patterns
    • Certificate expiration dates

​
Alerting Configuration

Set up alerts for:
  • High error rates (>5%)
  • Slow response times (>2s)
  • Database connection issues
  • Certificate expiration (30 days)

​
Next Steps

  1. Configure Service Settings - Set up your OAuth 2.0 service
  2. Register Clients - Add your applications
  3. Test Endpoints - Verify all endpoints are working
  4. Set Up Monitoring - Implement logging and alerting
  5. Go Live - Deploy to production
