Episode notes
Networking Is The Application Foundation
- Networking is the foundational “piping” that developers can ignore until connectivity or performance breaks.
- Understanding basics like latency and routing helps debug subtle performance issues.

- Large enterprises often reintroduce central network teams and abstractions that recreate a divide.
