Red Hat Enterprise Linux vs Ubuntu Server — Distribution Comparison
RHEL and Ubuntu Server are the two dominant Linux server distributions in enterprise. RHEL leads in regulated/legacy enterprises; Ubuntu dominates in cloud-native and developer-driven shops.
Quick Verdict
RHEL for compliance-driven enterprises with paid support requirements (FedRAMP, FIPS, etc.). Ubuntu for cost-sensitive deployments and cloud-native applications.

Frequently Asked Questions
Is RHEL really $349-799 per server per year?
Yes — Red Hat licensing is per-host subscription. Free alternatives: AlmaLinux, Rocky Linux (1:1 binary-compatible RHEL forks, free).
Should I use Rocky Linux instead of RHEL?
Rocky and AlmaLinux are 1:1 binary-compatible with RHEL — same packages, same kernel, same configs. Free. Lose Red Hat support but gain $300-800/year per server.
Our Recommendation
Rocky Linux or AlmaLinux for cost-sensitive deployments needing RHEL compatibility. RHEL when paid Red Hat support is mandated. Ubuntu LTS for cloud-native / developer-friendly deployments.
