Fortress GraphQL API - Production Deployment Guide

🚀 Overview

This guide provides comprehensive instructions for deploying the Fortress GraphQL API to production environments with all security, performance, and scalability features enabled.

📋 Prerequisites

System Requirements

  • CPU: Minimum 4 cores, recommended 8+ cores for high throughput
  • Memory: Minimum 8GB RAM, recommended 16GB+ for production workloads
  • Storage: Minimum 100GB SSD, recommended 500GB+ for data persistence
  • Network: 1Gbps+ network connection for optimal performance

📈 Performance Tuning

Database Optimization

-- Create indexes for performance
CREATE INDEX CONCURRENTLY IF NOT EXISTS idx_users_email ON users(email);
CREATE INDEX CONCURRENTLY IF NOT EXISTS idx_users_created_at ON users(created_at);
CREATE INDEX CONCURRENTLY IF NOT EXISTS idx_data_table_id ON data(table_id);

-- Configure PostgreSQL for performance
ALTER SYSTEM SET shared_buffers = '256MB';
ALTER SYSTEM SET effective_cache_size = '1GB';
ALTER SYSTEM SET maintenance_work_mem = '64MB';

Redis Optimization

# Redis configuration
redis-cli CONFIG SET maxmemory 1gb
redis-cli CONFIG SET maxmemory-policy allkeys-lru
redis-cli CONFIG SET save 900 1 300 10 60 10000

Application Tuning

[server]
workers = 8
max_connections = 1000
request_timeout = 30

[cache]
enable_compression = true
compression_threshold = 1024
max_memory_usage = 2147483648  # 2GB

📚 Troubleshooting

Common Issues

High Memory Usage

# Check memory usage
kubectl top pods -n fortress

# Adjust memory limits
kubectl patch deployment fortress-api -p '{"spec":{"template":{"spec":{"containers":[{"name":"fortress-api","resources":{"limits":{"memory":"2Gi"}}}]}}}}'

Slow Queries

# Check slow queries
curl "https://api.fortress.example.com/metrics" | grep slow_queries

# Analyze query complexity
curl https://api.fortress.example.com/graphql \
  -H "Content-Type: application/json" \
  -d '{"query":"{ __schema { types { name } } }"}'

Security Issues

# Check security events
curl https://api.fortress.example.com/security/events

# Review blocked requests
curl https://api.fortress.example.com/security/blocked-requests
