FreeRTOS

FreeRTOS is a real-time operating system for microcontrollers, managed by AWS. It handles the low-level hardware interactions required for IoT devices, ensuring deterministic execution for critical tasks. The service abstracts the complexity of building custom RTOS solutions, providing a standardized kernel that developers integrate directly into their embedded firmware to manage resources and scheduling efficiently.

This setup suits teams building connected devices who need reliable, real-time performance without maintaining their own OS infrastructure. The main friction point is the lack of a free tier. Since the pricing model is strictly pay-as-you-go, you incur costs from the start, which can be surprising for hobbyists or small-scale prototypes expecting zero-cost entry points common in other AWS services.
