The production01 cluster hosts various services for the VMware NSX-T Data Center environment, including load balancing, VPN services, NAT, DHCP, and Edge Firewall. These services consume additional resources. Use of a large-sized edge VM is appropriate. This cluster should be used only in cases where VMware NSX-T Data Center Tier 1 centralized services are instantiated.
