What new AWS subnets should the Network team advise require creation for a brand new...

When establishing a landing zone in a brand new AWS region for NC2 with Flow Virtual Networking (FVN), the network team must provision specific subnets to support the management plane and the transit architecture. The first essential component is theFVN Overlay External Subnet, which resides within the Transit VPC and acts as the entry/exit point for traffic moving between the overlay network and external environments like the internet or on-premises data centers. The second requirement is a dedicatedPrism Central subnet, which is necessary to host the Prism Central instance that will manage the NC2 clusters within that region. These subnets provide the structural foundation for the software-defined networking overlay, ensuring that management traffic is properly segregated from user workload traffic and that the transit gateway logic has a designated physical network path.
