Technical articles on industrial data systems at the edge: reliability, supply-chain security, MQTT and Sparkplug B.
Typical MQTT brokers pass malformed Sparkplug traffic silently. What that costs you, what RelayQ enforces at ingress today, and what it does not yet.
How RelayQ fits on industrial gateways, ARM SBCs, and embedded Linux systems where every kilobyte counts.
How RelayQ, a deterministic edge runtime for industrial data systems, is built on a std-only core: zero third-party crates in the Lite build, twelve pinned crates when TLS is enabled on Linux. Why that removes most of the supply-chain risk a typical broker stack carries.
A typical OT platform pulls in a long tree of transitive dependencies. Each one is a potential SolarWinds.
How to map IEC 62443-4-1 secure development practices to your edge runtime selection and deployment.
