Networking

TCP/IP, DNS, load balancers, and VPCs — debug latency and outages in AI services.

Maturity level: L2 — Can Build

Six perspectives on Networking

Roadmap

Learn in Foundation alongside Linux — required for cloud and K8s depth.

Architecture

Connects users to APIs, models, and data stores.

Company

Listed for platform, SRE, and AI infrastructure roles.

Projects

Network diagram every architecture you design.

Interview

Troubleshooting and VPC/load balancer questions.

Career

Separates script deployers from production engineers.

What & Why

What: Fundamentals of how services communicate across networks and the internet.

Why: Production AI APIs fail on DNS, TLS, timeouts, and firewall rules as often as on model bugs.

Build this

Trace a request from client → ingress → pod → database and document every network hop.

Production reality

  • ! DNS failures
  • ! Connection timeouts
  • ! MTU issues
  • ! Certificate expiry
  • ! NAT exhaustion

Interview preparation

  • Explain how a request reaches a K8s pod
  • Debug intermittent 502 errors
  • VPC peering basics
