Alibaba Cloud Linux:Overview

This image is customized based on the Alibaba Cloud kernel. This image supports quick boot (Qboot) and boots instances from the kernel. Instances that are created from this image start faster than instances that are created from other images, and share the same default runtime as instances that are created from the standard image. This image has the following characteristics:

• The initial startup of instances is accelerated, whereas the subsequent startup of instances remains at normal speed.

• The memory initialization process is optimized and accelerated, devices that require a long period of time to start, such as mice, are modularized, and the kernel boot is accelerated.

• The cloud-init service is replaced with the AliyunInit service to reduce the amount of time that is required to initialize the operating system.

• The kernel of this image cannot be modified.

• This image does not support the following instance families: GPU-accelerated compute-optimized instance families, vGPU-accelerated instance families, FPGA-accelerated compute-optimized instance families, NPU-accelerated compute-optimized instance families, heterogeneous instance families, Super Computing Cluster (SCC) instance families, and security-enhanced instance families.
