What it means
The design must address addressing, routes, redundancy, encryption, bandwidth, DNS, monitoring, and the security boundaries between operating domains.
Why it matters
Hybrid links can improve migration and integration, but they can also extend implicit trust and allow a compromise to move across environments.
Practical focus
- Design redundant paths and test failover
- Limit route propagation and segment high-risk networks
- Monitor connection health and unusual cross-environment flows
Common mistakes
- Connecting entire networks before defining required flows
- Assuming a dedicated circuit is automatically encrypted
- Ignoring DNS and identity dependencies during failover
