Network Connectivity Center documentation
Network Connectivity Center lets you use a hub-and-spoke architecture for network connectivity
management. With this architecture, you can conduct data
transfer between your sites. Network Connectivity Center lets you create VPC spokes to
connect VPC networks together using various topologies. You can use NCC Gateway
spokes to enable security functions such as third-party Security Service Edge (SSE).
Network Connectivity Center also includes the Router appliance feature, which lets you use a third-party
network virtual appliance to establish site-to-site or site-to-cloud connectivity.
