Network Connectivity Center is an orchestration framework that enables network connectivity among VPCs that are connected to a central management resource called NCC Hub and it supports two types of spokes:

VPC Spokes: provide inter-VPC network connectivity at scale, reducing the operational complexity of managing individual pair-wise VPC Network Peering connections through centralised NCC Hub

Hybrid Spokes: provide VPC networks to on-premise or other cloud provider networks. These external networks can be reachable through any type of hybrid spoke, these type of spokes consisting of:

• HA VPN Tunnel
• Cloud Interconnect VLAN attachments
• Router Appliances VMs
