Infrastructure & Edge
Make the network path an explicit part of the system design.
Design DNS, routing, load balancing, and private connectivity so traffic behaves predictably across providers.
Every request crosses a network path that someone designed, or one that accumulated by default. DNS, anycast routing, load balancing, health checks, and private links to internal systems determine how an application behaves under failure long before application code runs.
This is where outages become confusing. Failover works in one region and not another. A private connection back to a data center becomes a single point of failure. Traffic steering rules are edited by hand until they no longer match the diagram.
Network Architecture makes that path deliberate. It gives the team a clearer way to design DNS, routing, load balancing, and private connectivity across Cloudflare, AWS, Google Cloud, and Azure, including the links back to on-premise and colocated systems. What matters next is predictable failure, clean failover, and traffic that can be steered on purpose.
Let’s get going
- Start where failover has never been tested — Pick one path where the failure behavior is assumed rather than proven, and make the actual behavior visible.
- Map the real traffic path — Trace DNS resolution, routing, load balancing, and private links end to end so the topology reflects how traffic actually moves.
- Make steering explicit — Move traffic decisions into declared policy rather than manual edits, so routing changes are reviewable and reversible.
Outcomes
- Predictable failover — Health checks, routing policy, and origin selection behave the same way in a real incident as they do in the diagram.
- Clean private connectivity — Internal systems, data centers, and cloud regions connect through paths that are documented, monitored, and replaceable.
- Traffic steered on purpose — Load, geography, cost, and provider mix become inputs to routing rather than side effects of it.
