📊 Post-Deployment Checklist
· Change all default passwords · Enable firewall (UFW) · Configure SSL/TLS · Set up intrusion detection · Regular security updates
· Enable Gzip compression · Configure CDN (CloudFront/Cloudflare) · Set up caching strategies · Database indexing · Load testing
· Application monitoring (Sentry) · Infrastructure monitoring (Datadog) · Log aggregation (ELK Stack) · Uptime monitoring (UptimeRobot) · Performance metrics (Google Analytics)
· Automated database backups · File storage backups · Disaster recovery plan · Regular backup testing
🛠️ Troubleshooting Common Issues
# Check MongoDB connection
mongosh "mongodb://localhost:27017" --eval "db.adminCommand('ismaster')"
# Check Redis connection
redis-cli ping
# Monitor memory usage
htop
docker stats
# Increase Node.js memory limit
node --max-old-space-size=4096 server.js
# Check SSL certificate
openssl s_client -connect yourdomain.com:443 -servername yourdomain.com
# Renew certificate
sudo certbot renew --force-renewal
This comprehensive deployment guide covers everything from local development to production deployment with enterprise-grade infrastructure. The application is designed to be highly available, scalable, and secure for production use.
