Transitioning between Linux distributions can present challenges, but understanding these differences is the first step. This guide is designed for customers considering a migration from Red Hat Enterprise Linux (RHEL) based distributions – including CentOS, AlmaLinux and Rocky Linux- to Ubuntu in a public cloud environment, but the comparison is also true in other environments.
When moving between a RHEL-based distribution and Ubuntu, it’s essential to consider a range of factors. This includes the release cadence and licensing model, package management, service configuration, security posture and other system-level differences.
Public clouds add another layer of complexity, with integration, tooling, and cloud-specific features playing a critical role in the migration process.
This guide covers the following topics:
- Key differences between RHEL and Ubuntu for enterprise administrators
- Enterprise security and support model
- Migration strategy guide
- Administration cheat sheet
- Example migration
Ubuntu is built to provide maximum security, and if you need access to additional features such as professional support, compliance (FIPS, STIG, CIS, CMMC), and CVE patching automation, these are also available with a Ubuntu Pro subscription.
