Wind River
VxWorks is the RTOS behind Mars landers and commercial avionics: deterministic scheduling, ARINC 653 time and space partitioning, and DO-178C certification evidence up to DAL A. Wind River Linux is a Yocto Project–based distribution with CVE tracking and long-term maintenance. Helix Virtualization Platform adds a Type 1 hypervisor that runs unmodified guest operating systems side by side, so certified and non-certified workloads share one multi-core SoC instead of separate boxes.
Ubuntu · Kubernetes · OpenStack
Canonical / Ubuntu
Ubuntu Pro extends security maintenance to ten years across the main and universe archives, with FIPS 140 validated crypto modules, CIS and DISA-STIG hardening profiles and kernel livepatching that closes vulnerabilities without a reboot. For infrastructure, MicroK8s and Charmed Kubernetes cover edge clusters and Charmed OpenStack covers private cloud. Ubuntu Core delivers a transactional, fully containerised OS for devices, with secure boot and full-disk encryption.
RHEL · OpenShift · Ansible
Red Hat
Red Hat Enterprise Linux gives a ten-year lifecycle, a stable kernel ABI and FIPS mode for regulated deployments; RHEL for Edge adds image-based rpm-ostree updates with automatic rollback for sites nobody can visit. OpenShift runs Kubernetes with integrated CI/CD, service mesh, and single-node and three-node topologies for constrained locations. Ansible Automation Platform handles fleet configuration and compliance remediation at scale.
Hard real-time Linux · HIL simulation
Concurrent Real-Time
RedHawk Linux is a RHEL-compatible kernel tuned for guaranteed worst-case response rather than average throughput: shielded CPUs, deterministic interrupt handling, user-level pre-emption control and microsecond-scale jitter under full load. NightStar tools trace, debug and tune without perturbing the timing they measure. Paired with SIMulation Workbench, it drives hardware-in-the-loop rigs, radar processing and high-rate data acquisition.
File systems · Flash management
Tuxera
Embedded file systems decide whether a device recovers cleanly from a crash or corrupts silently. Tuxera's transactional file systems — NitroFS, Reliance Edge and EdgeFS — use copy-on-write and dynamic transaction points so data and metadata stay consistent through power loss on eMMC, UFS, SSD and SD. FlashFX Tera adds wear levelling, bad-block management and error correction over raw NAND, while licensed Microsoft exFAT, NTFS and FAT implementations keep removable media interoperable across Windows, Linux and VxWorks.
