Amazon FreeRTOS vs Linux Kernel: What are the differences?
# Introduction
This markdown will highlight the key differences between Amazon FreeRTOS and Linux Kernel.
1. **Operating System Type**:
Amazon FreeRTOS is a real-time operating system designed for microcontrollers, providing IoT developers with easy-to-use tools and libraries for building connected devices. On the other hand, Linux Kernel is a full-fledged operating system used in a wide range of devices, from servers to embedded systems.
2. **Memory Management**:
Amazon FreeRTOS is optimized for memory-constrained devices, with a small footprint and efficient memory management to run on low-power devices. In contrast, Linux Kernel is designed for larger systems with more memory resources and offers advanced memory management capabilities.
3. **IO and Device Support**:
Amazon FreeRTOS provides support for a wide range of IoT peripherals and sensors, making it easier for developers to interface with hardware devices. Linux Kernel, on the other hand, has extensive driver support for a wide range of devices, making it suitable for a variety of hardware configurations.
4. **Community and Ecosystem**:
Linux Kernel has a vibrant open-source community with extensive documentation, support, and a large number of developers contributing to its ecosystem. Amazon FreeRTOS, being a newer platform, is still developing its community and ecosystem but benefits from Amazon's resources and support.
5. **Real-Time Capabilities**:
Amazon FreeRTOS is designed for real-time applications, with deterministic behavior and low latency, making it suitable for time-sensitive IoT applications. Linux Kernel, while it can be configured for real-time tasks, may not offer the same level of predictability and responsiveness as a dedicated real-time operating system.
6. **Licensing**:
Linux Kernel is distributed under the GNU General Public License, which mandates the sharing of modifications and derivative works. Amazon FreeRTOS, on the other hand, has a more permissive license that allows for proprietary modifications and commercial use without the requirement of sharing the source code.
# Summary
In Summary, Amazon FreeRTOS and Linux Kernel differ in terms of their operating system type, memory management, IO and device support, community and ecosystem, real-time capabilities, and licensing restrictions.
