System Design Learning Is Purely Theoretical With No Real Load Simulation
Engineers learn system design patterns in isolation through diagrams and interview prep, with no way to see how those designs actually behave under realistic load. The gap between understanding architecture conceptually and observing its failure modes is rarely bridged outside of production incidents.
OML Labs Browser-Based Network Simulator Listing
This entry describes OML Labs, an existing self-hosted browser tool for simulating real Cisco, Juniper, Linux, and Windows network topologies with packet capture; it is a product listing rather than a reported problem.
SREs Have No Safe Way to Practice Real Production Incidents
Aspiring and junior SREs lack a way to practice real incident response, infrastructure-as-code, and observability work against production-grade systems without either the risk of a live environment or the low retention of passive, slide-based courses.
