Episode notes
Why EVPN VPWS was Chosen
- Megaport chose EVPN Virtual Private Wire Service to satisfy customer demands for redundancy and scalability in their network.
- EVPN also enables better scaling with BGP and supports features like Layer 3 VPNs not available with the legacy solution.
Network Database as Source of Truth
- Megaport maintains a comprehensive in-house database as the single source of truth for network state and resource allocation.
- This database actively syncs with network changes to prevent config drift and validate network resources like VLANs and IPs.
Megaport's Massive Network Scale
- Megaport's network spans 975 data centers across 26 countries and includes about 1,500 MPLS devices impacted by the EVPN rollout.
- They handle around 30,000 VXC services out of a total 50,000 network services, making migration a significant effort.
