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.
AWS and Azure provide managed IoT device management features that can schedule and track OTA-style update rollouts. Google Cloud and OCI don’t have a single, directly equivalent, first-party OTA update service; OTA is typically implemented using device management patterns plus storage, messaging, and CI/CD tooling.
