Due to reasons such as end of product life, end of third-party support, and evolution of open source projects, Alibaba Cloud may end technical support for some services after a period of time since the release of the services. You can learn more about the technical support plans of services or software to update the services or software to general availability (GA) versions in a timely manner. When you use Elastic Compute Service (ECS), you must pay attention to the lifecycle plans of the operating systems contained in the images used to create instances. These plans are published in the official websites of the operating systems.

Note When an operating system version comes to its end of life (EOL), Alibaba Cloud stops providing support for the ECS instances that use the operating system version.
  • Alibaba Cloud Linux 2 is an operating system provided by Alibaba Cloud. Before Alibaba Cloud Linux 2 comes to its EOL, Alibaba Cloud provides technical support for problems that occur when you use Alibaba Cloud Linux 2.
  • If you are using a third-party operating system, contact the operating system vendor or open source community for technical support. Alibaba Cloud also provides information about image- and system-related problems. If a third party vendor stops supporting or maintaining an operating system, Alibaba Cloud also stops providing corresponding technical assistance.
