Ubuntu 22.04 LTS represents the sweet spot between stability and modernity. It ships with Linux kernel 5.15, which includes mature support for io_uring, WireGuard, and BPF-based networking - features that matter for high-performance server workloads. The LTS designation guarantees five years of free security updates with an additional five years available through Ubuntu Pro.
For production environments, 22.04 offers a battle-tested foundation. It has been in the field since April 2022, meaning the vast majority of edge-case bugs have been identified and patched. Libraries, runtimes, and frameworks are well-tested against this release, reducing the risk of unexpected compatibility issues.
AnubizHost provisions Ubuntu 22.04 from a minimal cloud image that includes only essential packages. This gives you a clean baseline with a small attack surface, fast boot times, and maximum available RAM for your applications rather than unnecessary system services.
