HarmonyOS is an operating system developed by Huawei, designed to work across a wide range of devices including smartphones, smart TVs, wearables, and IoT (Internet of Things) devices.

It was developed as an Android substitute and first released in 2019 in reaction to U.S. government limitations on Huawei that prevented it from accessing Google’s Android ecosystem.

Here are some key features of HarmonyOS:

1. Unified Operating System for Different Devices:

The intention behind the creation of HarmonyOS was to integrate many devices under a single operating system. Huawei envisions a future where smartphones, TVs, smartwatches, IoT devices, and even cars all run on HarmonyOS, allowing users to seamlessly transition between devices.

On the other hand, smartphones are the primary target of iOS and Android.

2. Microkernel Design for Security and Performance:

The microkernel architecture used by HarmonyOS differs from the monolithic kernels used by operating systems such as iOS and Android.

Because a microkernel only contains the necessary parts (such as memory management, basic scheduling, and inter-process communication, or IPC), security is enhanced and performance is accelerated.

Additionally, HarmonyOS’s microkernel is designed to isolate critical services, making it harder for vulnerabilities in non-essential services to affect the core functions of the system. This enhances both security and stability.

3. HarmonyOS Distributed Architecture:

One of the standout features of HarmonyOS is its distributed architecture.

Devices in a networked ecosystem can easily share resources thanks to this operating system. For example:

• A user can start a task on one device (such as watching a video on a smartphone) and seamlessly transfer that task to another device (like a TV or tablet) without interruption.
• In the HarmonyOS environment, devices can function as a single “super device,” sharing resources, storage, and processing power.

This design promotes collaboration between devices in a smart home environment.

This is making it easier for them to communicate and share resources.

4. Cross-device Development Framework:

Developers can create applications that run across multiple types of devices with a single code base.

This is reducing the need for separate development efforts for different platforms. HarmonyOS provides a distributed UI framework that adapts the user interface based on the device the app is running on.

For example, the same application could have a smartphone layout when running on a phone, a larger tablet or TV layout on larger screens, and could potentially interact with other devices (like wearables) at the same time.

5. HarmonyOS Versatility and Adaptability:

HarmonyOS is not limited to high-end devices but can be scaled down for use in devices with limited resources, like IoT (Internet of Things) devices such as smart appliances, sensors, and other connected gadgets.

This scalability helps in building a more comprehensive ecosystem where various types of devices can operate efficiently under the same operating system.

6. App Ecosystem and Compatibility with Android:

A major challenge for any new operating system is its ecosystem of apps. To address this, HarmonyOS is compatible with Android apps, meaning it can run Android applications with minimal adjustments. This helps in reducing the barrier for users switching from Android-based phones to HarmonyOS devices.

HarmonyOS also encourages the development of native apps through its own platform and tools, which are optimized for its microkernel architecture and distributed capabilities. Huawei offers development tools to help create apps that fully leverage the cross-device experience.

7. HarmonyOS is Open-source Approach:

Huawei has positioned HarmonyOS as open-source, similar to how Google handles Android through the Android Open Source Project (AOSP). By making HarmonyOS open-source, Huawei hopes to attract developers and manufacturers to contribute and build devices powered by HarmonyOS. This is strategic move to encourage its adoption outside Huawei’s ecosystem.

8. Global Adoption and Challenges:

• China: HarmonyOS is used within Huawei’s ecosystem in China, where Huawei devices no longer have access to Google’s Android services.
• This has pushed HarmonyOS as the primary OS for Huawei smartphones and other products.
• Global: Outside China, HarmonyOS faces the challenge of competing with the dominant players, Android and iOS. Its success largely depends on how well it can integrate with international app ecosystems and how it can differentiate itself through features like the distributed architecture.

In summary, HarmonyOS is a strategic move by Huawei to create a unified, cross-device operating system that leverages a microkernel for performance and security, supports a distributed ecosystem for seamless device collaboration, and is open-source to encourage broader adoption. Its potential lies in its ability to create a cohesive smart device ecosystem and the extent to which it can attract developers and manufacturers to the platform.
