According to Huawei Consumer Business CEO Richard Yu, the operating system is open-source, and was built with four key building blocks in mind:
A deterministic latency engine Improved security through a Trusted Execution Environment A modularised format which can adapt to various hardware types A distributed artchitecture Yu said that due to these four considerations, Harmony OS will be both faster and safer than Android.
It is built to adapt to whichever device it is installed on – meaning it can be deployed across a vast range of device types – making it closer to Google Fuchsia than to Android in its functionality.
This will also mean that app developers will only need to develop their software once, and it will run across a variety of hardware types.
While Harmony OS is currently expected to be used primarily with IoT products such as wearables and smart displays, if Huawei loses access to the Android operating system, it will be capable of deploying Harmony OS onto its smartphones immediately.
