Red Hat Enterprise Linux 10

The industry's leading commercial Linux platform. RHEL 10 (2025/2026) introduces the 'Lightspeed' AI assistant, Kernel 6.12, and initial FIPS-validated post-quantum cryptography. It offers a 10-year lifecycle and an unmatched certified hardware/software ecosystem. However, its high cost and the 2023 restriction on public source code access make it restrictive for developers who prioritize 1:1 FOSS transparency.
