Harmony OS Launch Event in English @ Huawei - HarmonyOS HDC2019 - Huawei Developer Conference 2019

The OS for all scenarios .
Harmony in Chinese talks about the beginning of the earth and to use a closed pronunciation for their Chinese character Hongmeng in English it is called harmony as we want to bring more harmony and more convenience for the world.
Harmony OS is the world's first microkernel based distributed OS for all scenarios as mentioned Google is also working on its microkernel based OS , but it is not realized yet .
As for the harmony of us it is the distributed OS for all scenarios as we have the distributed architecture so that it is born smooth it has secured kernel and it can enable shared ecosystem.

In this way it can provide services and support for the fully connected world at the same time we have our distributed architecture as it is our first level device OS .

And that's distributed architecture we have our soft-bus we have distributed virtual-bus-hardware virtualization distributed data-management and distribute data-scheduling .
And our virtualized-Hardware can function as shared resources and to distribute a virtual bus can connect multiple devices .
No matter is the camera, speaker ,or other devices even the sensor and computing devices .
They now are the hardware resources that is already a pool so with the virtual-bus .

The distributive virtual bus was one account of users all your devices .

The distributed virtual bus manages to reduce the latency achieve higher-throughput .
And even if the PLC is as high as 25% a user experience is still guaranteed .
The HarmonyOS has another feature that is for smooth .
The Linux and UNIX OS is today , are designing the system in the way that treating all the resources fairly .
They are being server-load oriented , that means on a highway .
The faster running vehicles and the slow running vehicles , are the trucks lorries and the bicycles .
They can just wonder on any of the links as they want .
In that way is difficult to achieve the low-latency and the fast and smooth operation of the system .
So the HarmonyOS changed the operation we have designed the passing-lane, fast-lane, slow-lane ,and bicycle-lane .
And we apply the technologies to dynamically analyze-and-predict the payload so as to precisely allocate resources according to the demands of different applications .

And we are also comparing with Fuchsia as you can see our IPC performance is three-to-five times higher than these two offerings .
Additionally, another reasons we're using the microkernel is to ensure the security of the kernel.
We're about to enter the era of the microkernel-era we need to ensure its security .
The HarmonyOS-microkernel is now commercially deployed on our tablets-and-handsets , among other smart devices launched after May 20 .
The microkernel is deployed in the trusted execution environment , so it can better ensure the security of the security-critical applications such as payment and biometric authentication .

The HarmonyOS we're launching today , is using microkernel architecture , and we look forward to seeing more OS using the microkernel architecture in the future.

The formal verification methods well has its own catch that means if we're using traditional program code you only need one line of code .
However if you use the formal verification-methods you will have to deploy 100lines of codes and that's why we're using microkernel .
With a smaller kernel you can comprehensively deploy the formal methods of verification .
In the past the formal ratification methods is only used in the security-critical fuels such as aerospace and chipset-design .
However today we are introducing the formal methods to the OS design and development.
The microkernel does not have the route privilege .
The Unix Linux and Android , they have the root access or route privilege .
It is like the key the master-key to every door in your house .
But now with the microkernel being used as you can see , the external-services are put outside kernel , such as the filesystem-management and memory-management , they all had their own locked .

The Harmony OS can ensure the security across different scenarios of different devices , and that is all enabled by the microkernel architecture .
Today , we have the HarmonyOS architecture as shown here .
So we still keep the Linux-kernel and the UNIX-kernel as well as other Android applications .
We also keep the light-OS here as part of the kernel .
And on top of the kernel we have to distribute a virtual-bus and framework .
program framework etc so as to be more compatible with more applications.
We are also deploying our compiler and the multi-device IDE to support the performance of harmonyOS but in the future we hope that we can replace the Linux kernel light OS kernel with our micro-kernel of HarmonyOS.
And in the future who will also be compatible with other applications .
We hope that all applications can be smoothly deployed and operated on our OS .
We are supporting the applications developed by different platforms such as HTML5 , Linux application , Android applications .

Our compiler another hightlight , it after is launched it supports the multi languages , no matter is C++ or C languages .
It is supported by our compiler our compiler also supports Java, Kotlin, and JavaScript.
All languages are supported by the our compiler,
It even supports the hybrid programming .
We want sometimes you will use C++ for complex application, but for some simple application you may be using Kotlin .
So no matter which languages you are using during the programming , our compiler can handle all the hassle for you .
More than system that the performance has been boosted by more than 60% with the our compiler being applied.
Our distributing-capability is providing a kit to support the application development across different devices with our kit.
We are able to easily develop applications for different devices.
In the past, none of the OS who supported, but with our kit, today you can easily develop applications for different devices.

We support Google's Android ecosystem as we give the priority to using Google's Android operating-system .
However if we cannot use it in the future then we can immediately switch to the HarmonyOS .
Compared with Android we have higher performance, because of its distributed capability so as to support the all scenarios in the future .
What I would like to share with you is that we can start using HarmonyOS at any time .

I would like to also share with you another piece of important news.
HarmonyOS, it will be open-source.
We'll want to build a global operating-system .
So that it will not be used by Huawei alone .
Instead, making it open-source, can also introduce the other parties .
So that together we can jointly built the next-generation leading operating system.
Thank you very much.
Thank you.
Thank you for attending HTC.
We hope that together we can build a stronger HarmonyOS, and a better ecosystem.
