Over-The-Air Updates - method of remotely distributing firmware and software updates to IoT devices without physical access. Like updating your phone automatically while you sleep, but for industrial equipment and connected devices.
An electric vehicle manufacturer pushes battery optimization updates to millions of cars overnight, improving range without requiring dealership visits.
OTA updates are typically implemented via an IoT device management layer that can target devices, stage rollout waves, verify success, and roll back. AWS commonly uses IoT Device Management Jobs to orchestrate firmware/software deployments. Azure commonly uses Device Update for IoT Hub (integrated with IoT Hub) to manage and deploy updates. Google Cloud does not offer a single first-party, dedicated OTA update product in the same way; OTA is usually built using partners or custom pipelines (e.g., device fleet management + artifact hosting + Pub/Sub/Cloud Run/Cloud Functions). Oracle Cloud Infrastructure does not have a widely used, direct equivalent dedicated to OTA firmware update orchestration; implementations are typically custom or partner-based.
