Networking
How traffic gets routed to and around the system.
Why we need this / what value this brings
How traffic reaches (and moves within) the system affects latency, security, and availability.
When to use this
Foundational decisions (DNS, VPC layout) are made early and are annoying to change later — get the shape right before scaling traffic.
How to use or implement this
Keep it as simple as the current scale requires; most of this is exam/interview knowledge until Localz has multiple instances/regions.
