Unveiling Huawei: Harmony OS

The image showcases the evolution of the HarmonyOS architecture, highlighting key changes between the current and future ("to-be") states. Let's break down the critical differences:

Kernel Level:

• Current: The current architecture utilizes a hybrid kernel approach, incorporating both the Linux kernel and the HarmonyOS microkernel. LiteOS is also present, potentially for low-power IoT devices.
• To-be: The future architecture aims for greater independence and security by solely relying on the HarmonyOS microkernel. This eliminates the dependence on the Linux kernel, offering potentially enhanced performance and a more streamlined design.

Core Services:

• Current & To-be: Both architectures maintain similar core services, including multiple runtime environments (supporting Huawei ARK compiler, web, etc.), general system services, IoT services, distributed data management, device virtualization, and UI & graphics capabilities.
• Difference: The "to-be" architecture introduces refined resource management with dedicated components for file systems, power management, RAM management, and device drivers. This suggests a focus on optimization and efficiency.

App Framework:

• Current & To-be: Both architectures support a multiuser program framework encompassing HarmonyOS, web, and other potential technologies. This ensures compatibility with various applications and user experiences.

Additional Observations:

• The Huawei ARK Compiler and multi-device IDE remain consistent across both architectures, emphasizing their importance in the HarmonyOS ecosystem.
• The removal of the "distributed virtual bus" in the "to-be" architecture could indicate a shift towards a more direct and efficient inter-component communication method.

Potential Implications:

The transition to a HarmonyOS microkernel-based architecture signifies Huawei's commitment to building a self-reliant and secure operating system. This move may lead to:

• Enhanced Security: The microkernel design inherently minimizes the attack surface, potentially leading to a more secure system.
• Improved Performance: A streamlined kernel can result in faster boot times and smoother overall operation.
• Greater Flexibility: The microkernel architecture allows for modularity and easier adaptation to different devices and use cases.
• Ecosystem Challenges: Moving away from the Linux kernel might pose initial challenges in terms of application compatibility and developer adoption.

HarmonyOS uses a layered approach with four main parts:

1. Kernel Layer: This is the foundation, providing core functions like process management, memory handling, and device interaction. HarmonyOS can use different kernels depending on the device.
2. System Service Layer: This layer sits above the kernel and provides essential services like networking and security.
3. Framework Layer: This layer offers tools and functionalities for app development, making it easier for programmers to build applications.
4. Application Layer: This is where user-facing apps reside, including those from the AppGallery, quick installation-free Quick Apps, and lightweight Meta Services.

HarmonyOS also boasts some unique features:

1. Super Device: DSoftBus, a communication base, allows you to connect separate devices into a single "Super Device." This lets you control one device with another and share data seamlessly across them.
2. Security: To safeguard sensitive data, HarmonyOS utilizes a Trusted Execution Environment (TEE) microkernel within the hardware. This isolates sensitive information during storage and processing.
3. Integration with Vehicle Systems: HarmonyOS can be integrated with the vehicle's existing systems and sensors to enable features such as advanced driver assistance systems (ADAS), vehicle-to-everything (V2X) communication, and autonomous driving capabilities.
4. Customization and Flexibility: HarmonyOS provides flexibility for automakers to customize and tailor the operating system to meet their specific requirements and branding preferences. This customization capability enables automakers to differentiate their vehicles and create unique user experiences.

Overall, HarmonyOS for Huawei Auto represents a significant advancement in automotive technology, offering a versatile and adaptable operating system tailored for the connected and autonomous vehicles of the future. However, it's important to note that details about HarmonyOS for Huawei Auto may evolve over time as Huawei continues to develop and expand its capabilities in the automotive sector.

The evolution of the HarmonyOS architecture demonstrates a strategic move towards a more independent, efficient, and secure operating system. This could have significant implications for the future of Huawei's device ecosystem and its role in the global tech landscape.
