Huawei officially revealed its new microkernel-based, distributed operating system, HarmonyOS designed to deliver a cohesive user experience across all devices and scenarios today at Huawei Developer Conference today.
To Long Didn’t Read (TLDR):
Four Distinct Features Features of Harmony OS
- Seamless: First-ever device OS with distributed architecture, delivering a seamless experience across devices
- Smooth: Deterministic Latency Engine and high-performance IPC
- Secure: Microkernel architecture that reshapes security and trustworthiness from the ground up
- Unified: Multi-device IDE allows apps to be developed once and deployed across multiple devices \
HarmonyOS is a lightweight, compact operating system with powerful functionality, and it will first be used for smart devices like smartwatches, smart screens, in-vehicle systems, and smart speakers. Through this implementation, Huawei aims to establish an integrated and shared ecosystem across devices, create a secure and reliable runtime environment, and deliver a holistic intelligent experience across every interaction with every device.
Richard Yu, CEO of Huawei’s Consumer Business Group, says “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.”
What makes Harmony OS Different from others?
First-ever device OS with distributed architecture, delivering a seamless experience across devices
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 Harmony OS, 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.
Deterministic Latency Engine and high-performance IPC
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.
Microkernel architecture that reshapes security and trustworthiness from the ground up
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.
Multi-device IDE allows apps to be developed once and deployed across multiple devices
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.
Developer plan and ecosystem development
At today’s conference, Huawei also announced the evolution roadmap for HarmonyOS and its kernel. HarmonyOS 1.0 will be first adopted in its smart screen products, which are due to launch later this year. Over the next three years, HarmonyOS will be optimized and gradually adopted across a broader range of smart devices, including wearables, HUAWEI Vision, and head units for your car.
The success of HarmonyOS will depend on a dynamic ecosystem of apps and developers. To encourage broader adoption, Huawei will release HarmonyOS as an open-source platform, worldwide. Huawei will also establish an open-source foundation and an open-source community to support more in-depth collaboration with developers.
Harmony OS aims to bring incredible new benefits to consumers, equipment vendors, and developers. For consumers, it will bring a cohesive and powerful intelligent experience across all aspects of their lives. For equipment vendors, it will help them gain a first-mover advantage in the age of holistic intelligent experience, where 5G, AI, and IoT will see explosive growth. At the same time, HarmonyOS will enable developers to win over more users with less investment, and rapidly innovate services across all scenarios.
“We believe HarmonyOS will revitalize the industry and enrich the ecosystem,” said Richard Yu. “Our goal is to bring people a truly engaging and diverse experience. We want to invite developers from around the world to join us as we build out this new ecosystem. Together, we will deliver an intelligent experience for consumers in all scenarios.”
