The Platform system is the shared substrate the rest of the IoT Gateway is built on. It does not own product features; it owns the cross-cutting concerns that every other system needs: a trustworthy way to issue and rotate credentials, and a single place to see metrics, logs and traces.
Responsibility in one sentence
Provide the platform-wide capabilities — identity material (secrets and certificates) and observability (metrics, logs, traces) — as stable internal services so product teams never have to reinvent them.
Could not build diagram for model "example-iot".
Metrics, logs and traces pipelines for the whole platform.
Issues and rotates device certificates and service secrets via an API.
The platform aims for 99.9% availability — when it is degraded, product systems keep serving from cached credentials and buffer telemetry locally rather than failing hard.
