Cloud provider recommendations

AWS

• Full node: t3.xlarge or c5.xlarge
• Archive node: m5.2xlarge or c5.2xlarge
• Storage: gp3 with provisioned IOPS

Google Cloud

• Full node: n2-standard-4
• Archive node: n2-standard-8
• Storage: pd-ssd or pd-extreme

Azure

• Full node: Standard_D4s_v5
• Archive node: Standard_D8s_v5
• Storage: Premium SSD v2

DigitalOcean

• Full node: General Purpose 8GB
• Archive node: CPU-Optimized 16GB

Monitoring requirements

For production deployments, ensure you have:

• Prometheus: For metrics collection
• Grafana: For visualization
• AlertManager: For alerting
• Node exporter: For system metrics
• Log aggregation: ELK or Loki recommended

Security considerations

System hardening

• Keep OS and packages updated
• Configure automatic security updates
• Use SSH keys only (disable password auth)
• Configure fail2ban
• Enable firewall (UFW/iptables)
• Regular security audits

Pre-installation checklist

Before proceeding with installation, verify:

• Hardware meets minimum requirements
• Operating system is supported and updated
• Storage has sufficient IOPS
• Network bandwidth is adequate
• Firewall rules are configured
• System monitoring is set up
• Backup strategy is defined
• Security measures are in place
