As you know, CentOS 8 has ceased maintenance services on December 31, 2021, and CentOS 7 will also cease maintenance services on June 30, 2024. After that, CentOS will no longer support new software and patch updates. At that time, users' existing services developed using CentOS will be exposed to downtime and security risks at any time and cannot be restored promptly, which will bring significant risks to your running projects and services.How can we solve this problem?
To solve this problem, HUAWEI CLOUD has identified major risks to customers' services and launched Huawei Cloud EulerOS（HCE OS）. The HCE OS has strong compatibility. It provides professional cloud services for users from aspects of Hybrid Deployment of Online and Offline Applications in Container Scenarios, Secure and trustworthy, Rapid migration, Efficient O&M, and Professional Certification and resolves the impact caused by CentOS out of service. To ensure the normal operation of the business using the CentOS system, the HCE OS provides a migration tool that can smoothly migrate CentOS to HCE OS.
Efficiently compatible with CentOS deployment scenarios
The HCE OS has the technical capability to completely replace CentOS. It is fully autonomous and controllable, and continuously evolves based on the open-source community of openEuler. In terms of hardware compatibility, it supports 400 types of boards in 6 categories, basically covering mainstream computing products. In terms of software compatibility, it is 100% compatible with mainstream application scenarios (cloud-native, storage, database, big data, WEB, etc.). It passes the compatibility certification of over 5000 kinds of application software, and it basically can replace CentOS for various deployments.
Mature migration solutions for multiple scenarios
HCE OS has a mature relocation guide that categorizes various applications according to three types of applications: distributed cluster applications, primary backup applications, and standalone applications, and develops a corresponding relocation plan.
For distributed cluster software: such as big data and distributed storage, CentOS can be relocated without interrupting business, and based on the distributed software scaling and expansion mechanism, HCE OS can realize rolling replacement and smooth relocation. This migration solution has been used in the big data scenario of China Mobile Online.
For primary standby applications: such as databases. CentOS migration does not require interruption of business, and the backup application is relocated first, followed by the main application, based on the synchronization mechanism of the main and backup states for smooth migration. The migration solution has been tested in Huawei internal systems
For standalone applications: CentOS relocation requires business interruption and cutover relocation, which is the same as the original application redeployment method and is a mature solution.
Huawei Cloud EulerOS will effectively resolve the problems and risks faced by your services running on CentOS and help your services run smoothly.
In addition, from August 28 to September 30 is Huawei Cloud's annual B2B Enterprise Cloud Festival. During the promotion, high-performance Linux (including HCE OS) VM are discounted up to 45% off. Registering an Account and you can receive a free Linux (including HCE OS) VM 1500 hours.
If you have more business questions, please contact us. HUAWEI CLOUD will provide you with 1-to-1 professional solution consulting services.

Wow, thanks for sharing this information about CentOS 8 and 7 ceasing maintenance services.
It's definitely concerning to think about the potential risks to my existing projects and services. I appreciate that HUAWEI CLOUD is offering a solution with Huawei Cloud EulerOS. The compatibility and professional services sound like they will be a great fit for my needs. I also came across another option that may be worth considering. I found a website called https://tuxcare.com/extended-lifecyc...ended-support/ that offers extended lifecycle support for CentOS 7. They offer security and bug fixes for an extended period of time, which could be a great option for those who can't migrate to HCE OS right away.
