Resource discipline
Run one demo at a time, record resource usage, and stop simulations when not studying them.
Experiments
Labs
Controlled environments for learning before deployment.
Active lab
NVIDIA DSX Air Trial Log
DSX Air is used as a simulation environment for network topology, routing, segmentation, and data center operations. It is not treated as a production VPS.
First track
Cumulus Linux, EVPN, VLAN, MLAG, and centralized routing foundations.
Output
Topology notes, configuration summaries, and migration lessons for real infrastructure.
Safety rule
No lab result is trusted until the failure mode and rollback path are documented.
Lab queue
Next experiments
Cloudflare Pages release loop
Measure the full path from Git commit to production verification.
DNS failure drill
Practice recovering from a managed record conflict without touching mail records.
Network segmentation model
Map personal devices, lab systems, public endpoints, and management paths before adding services.
