running processes in isolation has been happening for a long time. (jails for instance, have existed for a very long time and freebsd has been used a lot for hosting services in the past). while i agree docker solved the UI/UX problem, it also introducted a massive security risk, as running unverified binaries in production is very easy for developers. Most shops don't have any private repository in use nor do they have the people (anymore) to build proper processes and systems around running code in production.
