Monitoring
Use Network Watcher, Connection Monitor, Firewall Logs, and NSG Flow Logs to visualize traffic paths and denial reasons.
Landing Zone Network Guide
8 Operations / DR, Monitoring, Standardization
For networks, being able to explain and fail over during incidents is key. Keep effective routes, Next Hop, logs, and DR procedures ready in normal times.
Key points of this chapter
- Save effective routes during normal operation
- Verify routes, DNS, and Firewall during DR
- Record before/after changes so you can roll back
Explanation note
First explain the flow with a diagram, then supplement only the key points in text. For those unfamiliar with networking, showing where traffic flows before terminology is effective.
DR
Verify east-west ExpressRoute, DNS, Firewall Policy, and app/DB failover as one integrated procedure. Even if only the network switches, recovery fails if name resolution or return paths fail.
Standardization
Deciding naming and design rules for routes, NSG, Firewall, Private Endpoint, and DNS speeds up reviews and incident response.
