current packages and a fast moving toolchain, hardened and self updating
Fedora Linux is the community distribution sponsored by Red Hat, and it is where a great deal of enterprise Linux technology appears first. This image is the operating system itself rather than an appliance: it boots hardened, fully patched and ready for you to build your own services on. Fedora Linux releases are supported for roughly 13 months, so this is the right base when you want recent kernels, compilers and runtimes, and an enterprise distribution is the right base when you need a multi year support window.
Patched to zero pending updates behind an automated gate before capture, with automatic security updates armed so the machine keeps patching itself. No account ships with a usable password, root is locked, and SSH host keys plus the systemd machine ID are generated per VM on first boot, so no two machines share a secret or an identity. SELinux stays enforcing, SSH is key only, and a paired deployment guide plus 24/7 cloudimg support come with it.
