Amazon FreeRTOS vs Flatcar Container Linux comparison

Amazon FreeRTOS (a:FreeRTOS) is an open source operating system for microcontrollers that makes small, low-power edge devices easy to program, deploy, secure, connect, and manage. Amazon FreeRTOS extends the FreeRTOS kernel, a popular open source operating system for microcontrollers, with software libraries that make it easy to securely connect your small, low-power devices to AWS cloud services like AWS IoT Core or to more powerful edge devices running AWS IoT Greengrass.

A microcontroller (MCU) is a single chip containing a simple processor that can be found in many devices, including appliances, sensors, fitness trackers, industrial automation, and automobiles. Many of these small devices could benefit from connecting to the cloud or locally to other devices. For example, smart electricity meters need to connect to the cloud to report on usage, and building security systems need to communicate locally so that a door will unlock when you badge in. Microcontrollers have limited compute power and memory capacity and typically perform simple, functional tasks. Microcontrollers frequently run operating systems that do not have built-in functionality to connect to local networks or the cloud, making IoT applications a challenge. Amazon FreeRTOS helps solve this problem by providing both the core operating system (to run the edge device) as well as software libraries that make it easy to securely connect to the cloud (or other edge devices) so you can collect data from them for IoT applications and take action.

Flatcar Container Linux is a lightweight, secure, and reliable operating system designed for running containers at scale with automatic updates and a minimal attack surface. The solution is easy to use and manage and has a simple and intuitive command-line interface and a powerful set of tools for managing containers and clusters. 

It supports various container runtimes, including Docker, Kubernetes, and Mesos. It can be deployed on various infrastructure platforms, including bare metal, virtual machines, and cloud environments. Flatcar Container Linux is an ideal choice for organizations deploying containerized applications in production environments.
