The Middle East-based cloud service provider, CSP, is planning to launch five data centers in Egypt, United Arab Emirates, Saudi Arabia, Qatar, and Turkey. CSP is looking for VLAN extension and DCIs…

VPWS (Virtual Private Wire Service) provides only point-to-point L2 pseudowire connections between exactly two sites and cannot support multipoint L2 connectivity across five data centers in a single broadcast domain.

L2TPv3 creates point-to-point Layer 2 tunnels between two endpoints and does not natively support multipoint any-to-any L2 extension across five sites without complex hub-and-spoke or full-mesh manual pseudowire configurations.

IPsec VPN operates at Layer 3 and encrypts IP traffic between sites but does not extend VLANs or L2 broadcast domains, so VMs at different sites cannot share the same subnet.

VPLS (Virtual Private LAN Service) is a multipoint Layer 2 VPN technology that creates a single virtual LAN across multiple geographically separated sites, allowing all five data centers to share the same L2 broadcast domain. This enables VMs at different sites to reside on the same IP subnet, which is a hard requirement when original and backup VMs must communicate as if co-located. VPLS supports any-to-any full-mesh L2 connectivity across all five sites using a single logical service instance.
