HarmonyOS

New HarmonyOS launched from Huawei

 

Huawei officially launched HarmonyOS or previously known as  Hongmeng OS at the Dongguan Developer Conference on August 9 2019, which is a new microkernel-based, distributed operating system designed to deliver a cohesive user experience across all devices and scenarios.

Richard Yu, CEO of Huawei’s Consumer Business Group, explained that “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 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.”

So, What is so special about this HarmonyOS?

Below are the 4 key technical features that HarmonyOS is focusing on:

1. Seamless: 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 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.

2. Smooth: 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.

3. Secure: 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). 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 attack is greatly reduced.

4. Unified: 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.

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.
