For environments requiring highly flexible and complex network addressing,Flow Virtual Networking (FVN)is the superior choice over standard native AWS networking. Native AWS networking is often restricted by the CIDR blocks of the VPC, and managing non-contiguous ranges across multiple subnets can become administratively burdensome.FVNuses an overlay architecture (Geneve) that abstracts the User VM networking from the physical AWS VPC infrastructure. This allows administrators to define virtual networks and subnets using any IP range, including multiplenon-contiguous CIDR ranges, without being constrained by the primary VPC address space. This flexibility is essential for large-scale deployments or multi-tenant environments where overlapping or non-standard IP schemes must be supported seamlessly.
