Alibaba Cloud may no longer provide technical support for specific services for a variety of reasons, such as end of lifecycle (EOL) of services, end of third-party support, or evolution of open source projects. When you use Elastic Compute Service (ECS), take note of the lifecycle plans of the operating systems contained in images that you use to create ECS instances. You can visit the official websites of the operating systems to obtain their lifecycle plans. This helps you update your instances to stable operating system versions at the earliest opportunity.
Background information
When an operating system version reaches its EOL, Alibaba Cloud no longer provides support for ECS instances that run the operating system version.
Alibaba Cloud Linux is an operating system provided by Alibaba Cloud. After Alibaba Cloud Linux reaches the EOL, Alibaba Cloud continues providing technical support for Alibaba Cloud Linux. For information about the Alibaba Cloud Linux 2 EOL plan, see Alibaba Cloud Linux 2 EOL guidance.
For other third-party commercial and open source operating system images, if the image providers no longer provide support or the operating systems reach their EOL, Alibaba Cloud ends support for the images. For information about EOL plans for CentOS, Red Hat, and Windows Server, see CentOS EOL guidance, and Windows Server EOL guidance.
If you use an EOL operating system, the following risks exist. To prevent risks related to system security, compatibility, and performance, we recommend that you create a migration plan at the earliest opportunity to migrate your business to a supported version of operating system.
Security issues: Security updates are no longer provided for EOL operating systems. As a result, the operating systems become vulnerable to attacks and hacking. This may result in customer information leakage, system service interruptions, and ransomware attacks, which adversely affects business continuity.
Compatibility issues: EOL operating systems may be incompatible with new hardware and software, which causes the system to crash or fail to run as expected. Compatibility issues may cause difficulties in upgrading hardware or application software in business systems, which adversely affects business development and competitiveness.
Reliability issues: EOL operating systems may encounter errors that result in system instability, data loss, or file corruption, which adversely affects business operations and data integrity.
Compliance issues: Using EOL operating systems may violate specific security and compliance standards with which specific business sectors and organizations must comply. In this case, customers may face legal liabilities and fines and miss business opportunities.
Maintenance costs: EOL operating systems no longer receive technical support. Therefore, the time and costs to maintain and manage the systems are higher. The systems are more likely to encounter failures and downtime, which compromises business continuity.
