What this session would cover
Proposed outline — the mentor finalises the agenda once this topic is scheduled.
- 1Why networking & internet infrastructure matters — the common problem: "It can't connect" issues take days because network basics are unclear.
- 2Core concepts in plain language: Network models, Ethernet, IP addressing, subnetting, routing, switching
- 3Going further: TCP, UDP, DNS, DHCP, TLS, VPNs
- 4Framework walkthrough: OSI / TCP-IP Models, SLI / SLO / Error Budgets, ITIL Practices, FinOps Framework
- 5Practical workflow, built live: A subnet plan, DNS/TLS inspection and a layer-by-layer troubleshooting runbook.
- 6How to measure it: Availability, Mean time to recovery, Incident frequency, Cost per unit of usage
- 7An illustrative case (a fictional example, not a client result), then live Q&A on your own situation
Who it's for
- • Students and freshers entering tech
- • Working developers and engineers
- • Tech leads and architects
You'd leave with
