Production hybrid architectures combine connection types for redundancy.
VPN backup for Direct Connect: Primary uses Direct Connect. If it fails, traffic routes through VPN.
Active-active: Both connections carry traffic. Instant failover.
Multiple Direct Connect locations: Connect from locations for geographic redundancy.
Routing:
- BGP manages failover
- Prefer Direct Connect over VPN
- Test failover regularly
Transit Gateway integration: Connect Direct Connect Gateway to Transit Gateway. All VPCs access on-premises through one connection.
