Does Huawei Cloud Have a Migration Solution for CentOS?

Updated on 2024-09-20 GMT+08:00

Background

CentOS Linux 8 ended on December 31, 2021, and CentOS Linux 7 ended on June 30, 2024. CentOS will no longer support new software and patch updates. CentOS services may be exposed to risks or even become unavailable. What's worse, they cannot be restored in a timely manner.

HCE can be a perfect alternative to CentOS. You can use our migration tool to easily migrate OSs such as CentOS or EulerOS to HCE. Additionally, you can benefit from professional services in cloud native hybrid deployment, security hardening, fast migration, efficient O&M, and professional certification.

Compatibility Evaluation

Technologically, HCE can replace CentOS. HCE is fully independent and controllable, and continuously evolves with astute contributions from the openEuler open-source community. Huawei Cloud EulerOS can work with 400 types of boards in the southbound direction, including mainstream compute products. In the northbound direction, Huawei Cloud EulerOS is 100% compatible with applications in mainstream application scenarios, such as cloud native, storage, database, big data, and web. More than 5,000 types of applications have passed the compatibility certification on Huawei Cloud EulerOS and can be alternatives to those running on CentOS.

To ensure the seamless migration from CentOS to HCE, you can use the compatibility evaluation tool to quickly scan the software to determine whether they are compatible with HCE.

For compatible software, the software configuration is not modified during the migration and does not need to be reconfigured after the migration. For incompatible software, the evaluation report provides workarounds for adaptation after the migration.

Migration Feasibility

Huawei Cloud has mature migration guides for the following types of applications:

  • Distributed clustered applications, such as big data and distributed storage. CentOS migration does not interrupt services, thanks to distributed software scaling.
  • Active/standby applications, such as databases. CentOS-to-EulerOS migration does not interrupt services. The standby application will be first migrated, followed by the active application. The active-to-standby synchronization allows for seamless migration.
  • Standalone applications: Services need to be interrupted during CentOS migration. This migration solution is mature and proven. It works like re-deploying the application on Huawei Cloud EulerOS.
