What is Logical Overlay?
A logical overlay is a network virtualization technique that creates a virtual network on top of an existing physical network infrastructure. It decouples network resources from their physical locations, allowing for greater flexibility, scalability, and efficiency in network management. Logical overlays are commonly used to create virtual private clouds (VPCs), software-defined networks (SDNs), and other virtualized network environments.

Logical Overlay Competitor Technologies
Fabric Path
A Layer 2 multi-path technology, similar to TRILL, that could be used instead of a logical overlay.
MPLS VPN
MPLS VPNs provide similar VPN functionality for connecting remote sites, competing with logical overlay networks which provides similar capabilities.
SD-WAN
SD-WAN solutions often utilize logical overlay technologies to create secure and flexible WAN connections, thus is a direct competitor.
VPC
Virtual Private Clouds (VPCs) offer logically isolated networks within a public cloud environment, competing with logical overlay approaches that provides similar logical network isolation and connectivity.
VPN
Traditional VPNs (IPSec, SSL VPNs) can be used to create secure tunnels between sites or users, competing with logical overlay networks.
