How Do I Select a Proper Operating System?
When choosing an IoT operating system (OS), it is important to evaluate hardware limitations, power consumption, network connectivity, development and maintenance costs, security, and ecosystem scalability. The following introduces two Huawei-developed OSs as examples.
- LiteOS is a lightweight IoT OS commonly used in resource-constrained environments. It is well-suited for power-sipping, real-time-capable, and small-form-factor IoT terminals, such as those in smart home, wearable industry, Internet of Vehicles (IoV), and industrial control applications. Additionally, LiteOS can serve as the foundation for an embedded system to deliver real-time operating capabilities. LiteOS has the following features:
- Lightweight: Small kernel for devices with limited resources
- Power-efficient: Optimized power management for longer service life
- Real-time: Functions for real-time applications
- Customizable: Modular design for kernel tailoring
- Open: Various components and SDKs for quick development
- OpenHarmony is a next-generation OS for smart devices in various scenarios, connectivity levels, and intelligence capabilities. It features a modular design that supports system components on devices with RAM resources ranging from 128 KiB to x GiB. Device developers can integrate system components based on the target hardware capabilities. OpenHarmony has the following features:
- Open-source: Flexible code acquisition, modification, and distribution
- Modular: Flexible component selection and tailoring based on device hardware resources and function requirements
- Compatible: Support for multiple hardware platforms and processor architectures, including Arm and x86
- Distributed: Inter-device data sharing, task scheduling, and resource collaboration
- All-scenario: Seamless connection available for various smart devices, including smartphones, smart TVs, wearable devices, and smart home appliances
- Streamlined: Unified APIs allowing one-time development for multi-device deployment
- Extensible: Abundant APIs and tools for flexible customization
