🧰 3. How to Identify AlibabaCloud3.2104 OS

You can check your OS version by running:

cat /etc/os-release

Or:

cat /etc/redhat-release

If you see something like:

Alibaba Cloud Linux release 3 (Soaring Falcon) 2104

Then you are running AlibabaCloud Linux 3 version 2104, which is based on CentOS/RHEL 8.

⚠️ 4. CentOS 8 End of Life (EOL)

CentOS 8 reached End of Life on December 31, 2021, which means no more official updates or security patches. AlibabaCloud Linux 3, however, is actively maintained by Alibaba Cloud, so even if it’s based on CentOS 8, it may continue to receive updates from Alibaba.

• ✅ Use AlibabaCloud Linux 3 if:

  • You’re running an ECS instance on Alibaba Cloud
  • You want better integration with Alibaba Cloud services
  • You need optimized performance for cloud workloads

• ❌ Avoid CentOS 8 if:

  • You need long-term support
  • You’re starting a new project (consider CentOS Stream or Rocky Linux instead)

Since CentOS 8 is EOL, consider:

• Rocky Linux (community rebuild of RHEL)
• AlmaLinux (another RHEL rebuild)
• Oracle Linux (free, RHEL-compatible)
• CentOS Stream (rolling-release version, upstream for RHEL)
