What is the main purpose of EVPN?

While EVPN operates in cloud environments, its primary purpose is not application-aware networking but rather providing scalable Layer 2/3 connectivity for multi-tenant services.

EVPN provides overlay connectivity (Layer 2/3 VPNs) over an underlay network, rather than simplifying the underlay itself.

EVPN (Ethernet VPN) leverages the MPLS or IP underlay to extend Layer 2 connectivity between different data center locations or within a single data center, providing a highly scalable and flexible solution for multitenancy. It uses BGP to distribute MAC address and IP address reachability information, enabling efficient host mobility, active-active redundancy, and optimal forwarding for both Layer 2 and Layer 3 traffic.

EVPN's focus is on network virtualization and connectivity, not specifically on advanced security features for IoT devices, although it can provide segmentation that supports security.
