Issues and solutions after image EOL - Elastic Compute Service

When an image reaches its end of life (EOL), Alibaba Cloud no longer provides technical support for the image. This topic provides answers to frequently asked questions (FAQ) about image EOL.

How do I handle the impacts of the EOL of CentOS Linux?
What are the EOL migration plans for CentOS Linux?
How do I perform security updates after Ubuntu 16.04 LTS reaches EOL?

Do CentOS 8 public images stop selling after CentOS 8 reached its EOL?
No, Alibaba Cloud continues to provide CentOS 8 images. Elastic Compute Service (ECS) instances that were created from CentOS 8 images are not affected. However, the community no longer supports or provides security updates for CentOS 8. Your business that is hosted on CentOS 8 instances is vulnerable to security threats. We recommend that you migrate away from CentOS 8 as soon as possible. For more information, see How do I handle the impacts of the EOL of CentOS Linux?
How do I obtain information about end of support for operating systems?
Alibaba Cloud may stop providing technical support for services due to various reasons, such as end of service lifecycle, end of third-party support, or evolution of open source projects. When you use ECS, take note of the lifecycle plans of the operating systems contained in the images that you use to create ECS instances. To obtain information about the lifecycle plans of operating systems, visit the official websites of the operating systems. For more information, see Maintenance support for operating systems.
