Operating System for IoT

• FreeRTOS

FreeRTOS is a popular real-time operating system (RTOS) for microcontrollers and small microprocessors. It’s widely used in embedded systems, particularly in the Internet of Things (IoT) domain.

Here are some key points about FreeRTOS:

• Open-source: FreeRTOS is distributed under the MIT License, making it free to use and modify for any purpose.
• Small footprint: FreeRTOS has a very small memory footprint, making it ideal for resource-constrained devices.
• Low power consumption: FreeRTOS is designed to be energy-efficient, making it suitable for battery-powered devices.
• Easy to use: FreeRTOS has a simple and well-documented API, making it easy for developers to get started.
• Scalable: FreeRTOS can be scaled to meet the needs of a wide range of devices, from simple sensors to complex systems.
• Feature-rich: FreeRTOS includes a wide range of features, such as task scheduling, memory management, and communication protocols.

• Ubuntu Core

Ubuntu Core is a specialized version of the Ubuntu operating system designed for IoT and embedded devices. It’s engineered for security, reliability, and ease of management in these environments.

• Snap-based: Ubuntu Core is constructed entirely of Snap packages, which are self-contained software bundles that offer enhanced security, isolation, and transactional updates.
• Transactional updates: Updates are applied in an “all-or-nothing” manner, ensuring system integrity and preventing partial updates or failures. If an update fails, the system reverts to its previous state.
• Immutable base system: The core operating system files are read-only, protecting them from accidental or malicious modification. This contributes to enhanced security and stability.
• Minimal footprint: Ubuntu Core has a small footprint, making it suitable for resource-constrained devices.
• Remote management: Devices running Ubuntu Core can be managed remotely through the Ubuntu One cloud service, enabling tasks such as application deployment, configuration, and updates.
• Long-term support: Canonical, the company behind Ubuntu, provides security updates and bug fixes for Ubuntu Core for up to 10 years, ensuring long-term support for devices.

• Windows IOT

Windows IoT, short for Windows Internet of Things, is a family of operating systems from Microsoft specifically designed for use in embedded systems and IoT devices. It offers enterprise-grade power, security, and manageability to IoT solutions, leveraging the familiarity and benefits of the Windows ecosystem.

• Key features of Windows IoT:
• Windows-based: Built on the Windows platform, providing familiarity for developers and compatibility with a wide range of hardware and software.
• Multiple editions: Available in different editions to suit various device types and requirements, including:
• Windows 10 IoT Core: A lightweight, headless version for low-power devices with limited resources.
• Windows 10 IoT Enterprise: A full-featured version for more complex devices, offering enterprise-grade features like device lockdown, remote management, and security.
• Windows Server IoT 2019: A server-based version designed for data aggregation from multiple IoT devices.
• Development tools: Integrates with Visual Studio and other familiar Windows development tools, making it easier for developers to create and deploy IoT applications.
• Cloud connectivity: Works seamlessly with Azure IoT Hub and other cloud services, enabling device management, data collection, and analytics.
• Security: Emphasizes security features to protect devices from cyberattacks, including secure boot, device lockdown, and encryption.
• Manageability: Offers tools for remote device management, configuration, and updates, simplifying deployment and maintenance.

• Mbed OS

Mbed OS is an open-source, operating system for ARM Cortex-M microcontrollers, specifically designed for the Internet of Things (IoT). It simplifies and accelerates developing connected devices by providing a rich set of features and abstractions.

• Key characteristics:
• Open-source: Free to use and modify under the Apache License 2.0, fostering a vibrant community and continuous development.
• Modular: Libraries and drivers are included only when needed, reducing memory footprint and simplifying builds.
• Easy to use: C/C++ programming interface with well-documented APIs and extensive learning resources.
• Real-time: Supports deterministic, multithreaded execution with optional RTOS (Real Time Operating System) for complex applications.
• Connected: Offers drivers for various popular connectivity protocols like Bluetooth Low Energy, Wi-Fi, and cellular networks.
• Secure: Integrates multi-layered security features including secure boot, memory protection, and encryption.
• Hardware agnostic: Runs on a wide range of ARM Cortex-M boards, providing flexibility for development and deployment.
• Benefits:
• Faster development: Streamlined development process with pre-built libraries and tools.
• Reduced complexity: Abstractions hide low-level hardware details, allowing developers to focus on application logic.
• Lower costs: Open-source nature and modularity minimize licensing and hardware development costs.
• Improved performance: Efficient memory management and resource utilization lead to optimized device performance.
• Scalability: Adapts to various device requirements and complexity levels.
