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.
All provide building blocks for OTA-style rollouts (device identity, targeting, job orchestration, and monitoring). AWS uses IoT Jobs for remote update tasks; Azure commonly uses IoT Hub with Device Update for IoT Hub for package-based updates; Google Cloud has no single first-party, dedicated OTA update service—OTA is typically implemented with partners or custom pipelines; OCI IoT Cloud Service can support device management patterns used for remote updates.
