Scenarios & Optimization

High-performance Linux Instances

The virtualization performance bottleneck challenges the developers when a large number of multi-threading applications run on high-performance instances in parallel. Alibaba Cloud optimizes Alibaba Cloud Linux and the virtual infrastructure to significantly reduce the overheads on the instances, providing stable and reliable support for multi-threading and high concurrency.

Optimized for ECS Bare Metal Instances

Alibaba Cloud Linux is tailored and optimized to guarantee the best performance on ECS bare metal instances.


Alibaba Cloud Linux provides container registries to simplify the deployment and management of applications. Alibaba Cloud Linux supports the standard cloud-native container ecosystem. In addition, we will soon migrate cloud-native applications from the Alibaba open-source ecosystem to Alibaba Cloud.

Community Partnership

Alibaba Cloud has established partnerships with the Kata Containers and Clear Linux communities. You can seamlessly deploy the Kata Containers solution on ECS bare metal instances. Alibaba Cloud also reduces the launch time of RunV containers. This guarantees the overall performance of the Kata Containers solution.
