The author created vpp-maglev, a suite of four Go binaries: maglevd (daemon), maglevc (CLI), maglevd-frontend (web dashboard), and maglevt (test utility). Key design principles include single source of truth via gRPC, restart neutrality with a two-phase startup warmup, diff-based reconciliation, and structured observability. The health checking system borrows HAProxy's rise/fall counter model with added hysteresis and jitter. The CLI supports prefix matching and tab completion inspired by Bird and SR Linux. The web dashboard uses SolidJS embedded in a Go binary with real-time updates via Server-Sent Events. The system is deployed in production at IPng Networks across four VPP machines in multiple cities. ## Full article daily.dev links to this article rather than hosting it.
