HPR3609: Linux Inlaws S01E57: Operating System Level Virtualisation and Martin's Faith

In this episode our two ageing heroes take a closer at operating system (OS) level virtualisation. The main different legacy virtualisation technologies like virtual machines (VMs) and this new-fangled approach is that the OS kernel remains the same across virtualisation domains, thus giving the hippsters and other followers of fashion a cheaper and potentially much faster solution than virtualising the kernel and surrounding hawrdware and all the rest of it. Plus more details on Martin's real faith. Don't miss out on this episode if you're interested in any of these...
