There’s no denying that SSH is the de facto tool for *nix server administration. It’s far from perfect, but it was designed with security in mind and there’s been a huge amount of tooling written over the years to make it easier to use. In addition, many popular products and just about every server deployment system integrates with SSH somehow. It is universally supported across pretty much all architectures and distributions, from Raspberry Pis all the way up to massive supercomputer clusters.
