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.

Let's look at its architecture.

This is the architecture of our HarmonyOS in a very bottom layer it's the kernel and on top of that basic services,
then program framework and this way we can support all kinds of devices including power vision, wearable services, hand unit services, speaker services ,and smartphone services

All those kinds of services can be supported with one single operating-system .
So that it is modular based decoupling as it enables elastic deployments.

Whatever the feature this device has it can use this HarmonyOS at the same time .
Because of our strong and flexible also narrow deployment capability were able to realize flexible adaptation .
So that it can support a wide range of memory-space from RAM size 2GB-level ,and KB-level .
So that for one operating-system it can be applied to different devices .

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 .
Their capability can be shared and caught by any of your device .

-
Later my colleague will show you a demonstration showing you how the distributed virtual-bus can call the hardware capabilities on different devices.
And this is the first this Huawei is the first one to achieve so.

Our distributed virtual bus has also introduced the simplified protocol .
So you may recognize this protocol stack with seven layer .
From physical layer all the way to the session presentation application layers there were seven layers of them .
But for the OS, our distributed virtual bus has simplified the four layers in the middle .

So as to reduce the payload consumed and that the simplification of the protocol stack we managed to boost the payload efficiency .

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 that's how we can achieve higher-efficiency and lower-latency .
And we're deploying the deterministic-latency-engine .

The response latency and latency fluctuation dropped significantly .
So you may worried about the IPC for a microkernel based architecture.
But you don't need to worried about that .
File-system that were management among other external kernel services.
They are the basic services .

If we're applying a monolithic-kernel-architecture then all the external-kernel-services are integrated together .
But now in the era of the microkernel .
How can we ensure the performance of IPC.

How many OS can deliver the best IPC performance.

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.
And another highlight of the HarmonysOS is the formal verification message .
It uses the formal verification can ensure the security comparing to the traditional methods .

--
There are always vulnerable --'tis in the OS you can use
There are always vulnerabilities in the OS .
-
You can use verification of the functions and scanning of the vulnerability and even simulate the attack to eliminate any risks of security , but there is no hundred-percent assurance to that .
--
However by deploying the formal ratification methods , we have fully verified the code matching design making sure that the correctness of the system can be verified
in a more comprehensive way .

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 .
And that's how we don't worried about having one master-key to open all the doors in your house .
And that's why ? .

By eliminating the route privilege we can ensure the security of the entire system .
We have changed the traditional monolithic-kernel architecture into two-layers , with one-layer of microkernel and another-layer of the external-kernel.
The EAL has issued us certification.
Our harmony OS is possible to get the five-plus level of certification .
We believe we are the number one in the entire world .
And will be part of the testing , and we are confident , that we can be the OS that is getting the certification higher than five.

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 .
They will all be a they will all be able to running on our OS in the future.

Another perk of the distributed OS for all scenario is to have a shared ecosystem .
So in the past you may have to develop a application for a watch , another application for your PC , and another application for your handset .
Then developers have to go through all the trouble to adapt your application to different devices .
But now, with IDE provided by Huawei , you can develop that application once and then deploy the application on multiple devices .
That's how we can create a shared ecosystem for a different application of different devices, for example a music player on your home, will be automatically adapted to the landscape mode on your infotainment-system in your car .
And the IDE enables the drag and drop for automatic adaptation .
So this is a demonstration of the IDE developers can easily use this environment for the application development.

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.

This is the history on a road map of HarmonyOS was started two years ago first working on the kernel.
Where we first used TEE from the smart device
starting from this year the HarmonyOS is applied to more devices and the first product will be the product that we were released tomorrow from honor.
As for the HarmonyOS microkernel it's well release it's 2.0 version next year, and 3.0 version the year after next.
So we will fully improve both the internal-part and external-part , so as to enhance the capabilities .
The HarmonyOS can be applied to different devices including our smart-phones, PCs, tablets, watches, and hand-units .
If you ask me what we will apply it to the smartphone, we can do it at any time but for the consideration of a better ecosystem.

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 .

Migrating from Android to HarmonyOS is not that difficult actually.
It is very simple maybe we can do that in just one or two days.
This is how small the workload of migration can be.
It can be easily migrated very convenient, because we offer a compatibility.

What we would like to share with
---
Because we offer a compatibility .
What we would like to share with you is that, in the future in PC, tablets, and all the other domains, we can use our strong operating system.

I like the operating systems others have been developing based on Linux .
We represent a entirely new generation of operating-system.
Our HarmonyOS is the genuine forward-looking next-generation operating-system as it enables AI capability and it enables different scenarios.
So again it is the microkernel based distributed operating-system for all scenarios.
Thanks to the distributed-architecture, and its flexibility, it has much stronger performance and all the other different advantages.

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.
Thank you very much.
