AWS VPC
Pros
- + Free core service — no charge for VPCs, subnets, route tables, or security groups
- + Deepest virtual networking feature set available: peering, Transit Gateway, PrivateLink, flow logs, traffic mirroring
- + 39 Regions / 120+ Availability Zones with real multi-AZ fault isolation
- + Native IPv6 (dual-stack and IPv6-only) at no extra charge
- + Free baseline DDoS protection via AWS Shield Standard
Cons
- - NAT gateways add up fast: $0.045/hour per AZ plus $0.045/GB processed
- - No SLA attached to VPC itself
- - Architecture-level cost opacity — public IPv4, cross-AZ and egress charges interact
- - Steep learning curve and AWS lock-in once topology grows
Nebula
Pros
- + Free and open source; no vendor sits on your data path
- + Proven at scale — Slack's overlay runs on 50,000+ documented production hosts
- + Modern, non-homegrown crypto: Noise Protocol Framework, Curve25519/P256, AES-256-GCM
- + Certificate-based identity with groups-style firewall rules enforced between peers
- + Direct peer-to-peer tunnels with NAT traversal; lighthouses handle discovery only
Cons
- - You run the PKI: CA key custody, one-year default CA lifetime, certificate signing per node
- - No GUI, no hosted control plane, no SSO in the open-source edition
- - Operationally steeper than WireGuard and much steeper than managed mesh products
- - Overlay IPv6 and mobile client polish lag the desktop experience
- - No support contract or SLA unless you buy the third-party managed offering
