HarmonyOS (HongMeng OS): Everything you need to know



On May 20, 2019, we were the first to report about Huawei’s own operating system – Hongmeng. After a round of rumors and news, Huawei finally unveiled Harmony OS AKA HongMeng OS at Huawei Developer Conference 2019.

On September 10, 2020, Huawei unveiled HarmonyOS 2.0 at Huawei Developer Conference 2020 (HDC 2020) with added new distributed capabilities, including software bus, data management, and security. Huawei also introduced an adaptive UX framework that allows developers to quickly reach tens of millions of new devices and users.

On June 2, 2021, Huawei began a brand new chapter of HarmonyOS with version 2.0 with a tagline of “One as All, All as One”. Simultaneously, Huawei announced the beta testing along with the general rollout for various Huawei devices in the shape of a huge upgrade roadmap.

According to Huawei, HarmonyOS will become an important aspect of Huawei’s ecosystem and gradually make its way to most of its devices over the course of the next few years.


What is HarmonyOS?

HarmonyOS (HongMeng OS) is a new microkernel-based, distributed operating system designed to deliver a new user experience across all devices and scenarios.

“We’re entering a day and age where people expect a holistic intelligent experience across all devices and scenarios. To support this, we felt it was important to have an operating system with improved cross-platform capabilities. We needed an OS that supports all scenarios, that can be used across a broad range of devices and platforms, and that can meet consumer demand for low latency and strong security.” said Richard Yu, CEO of Huawei’s Consumer Business Group.

“HarmonyOS is completely different from Android and iOS. It is a microkernel-based, distributed OS that delivers a smooth experience across all scenarios. It has a trustworthy and secure architecture, and it supports seamless collaboration across devices. You can develop your apps once, then flexibly deploy them across a range of different devices.” Richard added.


HarmonyOS is based on the four technical features described below:

1. Seamless Experience:

By adopting distributed architecture and distributed virtual bus technology, HarmonyOS offers a shared communications platform, distributed data management, distributed task scheduling, and virtual peripherals. With HarmonyOS, app developers won’t have to deal with the underlying technology for distributed apps, allowing them to focus on their own individual service logic.

Developing distributed apps will be easier than ever before. Apps built on HarmonyOS can run on different devices while delivering a seamless, collaborative experience across all scenarios.


2. Smooth Performance:

HarmonyOS will address underperformance challenges with a Deterministic Latency Engine and high-performance Inter-Process Communication (IPC).

The Deterministic Latency Engine sets task execution priorities and time limits for scheduling in advance. Resources will gravitate toward tasks with higher priorities, reducing the response latency of apps by 25.7%. The microkernel can make IPC performance up to five times more efficient than existing systems.

3. More Secure:


HarmonyOS uses a brand-new microkernel design that features enhanced security and low latency. This microkernel was designed to simplify kernel functions, implement as many system services as possible in user mode outside the kernel, and add mutual security protection. The microkernel itself provides only the most basic services like thread scheduling and IPC.

Harmony OS’s microkernel design uses formal verification methods to reshape security and trustworthiness from the ground up in a Trusted Execution Environment (TEE).

Formal verification methods are an effective mathematical approach to validate system correctness from the source, while traditional verification methods, such as functional verification and attack simulation, are confined to limited scenarios. Formal methods, by contrast, can use data models to verify all software running paths.

HarmonyOS is the first OS to use formal verification in device TEE, significantly improving security. In addition, because the HarmonyOS microkernel has much less code (roughly one-thousandth the amount of the Linux kernel), the probability of an attack is greatly reduced.


4. All in One:

Powered by a multi-device IDE, multi-language unified compilation, and a distributed architecture kit, HarmonyOS can automatically adapt to different screen layout controls and interactions, and support both drag-and-drop control and preview-oriented visual programming.

This allows developers to more efficiently build apps that run on multiple devices. With a multi-device IDE, developers can code their apps once and deploy them across multiple devices, creating a tightly integrated ecosystem across all user devices.

The Huawei ARK Compiler is the first static compiler that can perform on par with Android’s virtual machine, enabling developers to compile a broad range of advanced languages into machine code in a single, unified environment. By supporting unified compilation in multiple languages, the Huawei ARK Compiler will help developers greatly improve their productivity.
