Let’s break this down and clarify what each of these distributions is, and how they relate:
✅ 1. What is Alibaba Cloud Linux 3?
Alibaba Cloud Linux 3 is a Linux distribution developed and maintained by Alibaba Cloud for use on Elastic Compute Service (ECS) instances. It is based on Red Hat Enterprise Linux (RHEL) source code, similar to CentOS Stream and Rocky Linux.
- Optimized for performance and stability in cloud environments.
- Comes with long-term support from Alibaba.
- Designed specifically for ECS instances but can be used elsewhere.
- Includes custom patches, kernel tuning, and tools for monitoring and managing cloud workloads.
✅ 2. What is CentOS Stream 9?
CentOS Stream 9 is a rolling-release distribution that sits between RHEL development and Fedora.
- It is upstream of RHEL — meaning it gets features and updates before they are included in RHEL.
- CentOS Stream 9 is the successor to CentOS Linux 8.
- It is intended as a platform for developers to contribute to RHEL 9.x.
✅ 3. Are Alibaba Cloud Linux 3 and CentOS Stream 9 compatible?
Yes, they are broadly compatible, because both are derived from the same RHEL 9 source base.
| Feature | Alibaba Cloud Linux 3 | CentOS Stream 9 |
|---|---|---|
| Base | RHEL 9+ | RHEL 9+ |
| Package format | RPM / DNF | RPM / DNF |
| Compatibility | High compatibility with CentOS/RHEL packages | High compatibility with RHEL ecosystem |
| Use case | Cloud computing, optimized for ECS | Development, testing, production |
So you can generally run applications built for CentOS Stream 9 on Alibaba Cloud Linux 3, and vice versa — assuming there are no major customizations or patches applied by either vendor.
✅ 4. Key Differences
| Aspect | Alibaba Cloud Linux 3 | CentOS Stream 9 |
|---|---|---|
| Maintainer | Alibaba Cloud | Red Hat & CentOS Community |
| Support Lifecycle | Long-term supported (LTS), backed by Alibaba | Follows RHEL lifecycle (~5 years beyond release) |
| Customization | Custom kernel, tools, and optimizations for cloud | Close to upstream RHEL, minimal customization |
| Official Cloud Provider Support | Yes (on Alibaba Cloud ECS) | No specific cloud provider backing |
| GUI | Minimal/no GUI by default | Minimal/no GUI by default |
✅ 5. Which one should you choose?
-
Choose Alibaba Cloud Linux 3 if:
- You are using Alibaba Cloud ECS.
- You want optimized performance and support tailored for Alibaba’s environment.
- You need integration with Alibaba Cloud tools and services.
-
Choose CentOS Stream 9 if:
- You want a community-supported RHEL-compatible OS.
- You are developing for RHEL or contributing to its ecosystem.
- You’re not tied to Alibaba Cloud and want broader flexibility across cloud providers or on-premises.
✅ 6. Can I install CentOS Stream 9 packages on Alibaba Cloud Linux 3?
In most cases, yes. Since both distros are based on RHEL 9, their package ecosystems are compatible.
However:
- Always verify repository compatibility.
- Avoid mixing repositories unless necessary.
- Prefer using official Alibaba Cloud Linux repositories when possible for stability and support.
