Building Resilient IoT Infrastructure with Rust

Why Rust for IoT?

When we started building Iodibase, we knew that reliability wasn’t optional — it was the product. IoT deployments run in harsh environments: remote factories, agricultural fields, maritime vessels. When a device goes offline, someone has to physically visit it. That’s expensive, slow, and sometimes impossible.

Rust gives us three things that matter more than anything else:

  • Memory safety without garbage collection — No unexpected pauses, no memory leaks, no use-after-free vulnerabilities. Our devices run for months without restarts.

  • Zero-cost abstractions — The same code that runs on a Raspberry Pi runs on a Hetzner server. No performance tax for safety.

  • Fearless concurrency — MQTT brokers, REST APIs, and data pipelines all run concurrently without data races, guaranteed at compile time.

The Embassy Pattern

Iodibase is built around Rust Embassy, an async runtime designed for embedded systems. The key insight is that IoT infrastructure doesn’t need a heavyweight server stack — it needs a lightweight, deterministic runtime that can handle thousands of concurrent device connections with minimal memory footprint.

Table 1. Our architecture
Component Role

MQTT Broker

Handles device-to-cloud communication with QoS guarantees

REST API

Provides synchronous access to device data, configuration, and management

Time-series Store

Stores telemetry data with configurable retention (7 days to 1 year)

Integration Layer

Pushes data to Apache Iceberg, ClickHouse, or Motherduck for analytics

Configuration over Code

The most important design decision we made is that Iodibase is configured via TOML, not code. Drop a configuration file into your Embassy project, and you get:

  • Full device management

  • REST API endpoints

  • MQTT broker with authentication

  • Data retention policies

  • Integration targets

This means you don’t need to write infrastructure code. You declare what you want, and Iodibase provides it.

What’s Next

We’re currently working on:

  1. Apache Iceberg integration — Open table format for cross-platform analytics

  2. AI-assisted anomaly detection — Opt-in ML models that run on your data without leaving your workspace

  3. Multi-region failover — Automatic data replication across EU data centers

Stay tuned for more updates.
