VAX VMS could do it ~30 years ago. IBM's AIX has had high-availability since maybe version 5 so 15-20 years on that. Not only that but every component (DB2, WebSphere) was HA ready out of the box (granted ND licenses were like 100k a server). z/OS could do it as soon as it got TCP (40? 50? years). It's the same wheel being crafted every 10 years, just with a little spackle on top. The only thing that feels new to me is the gradual application (pun not intended) of math as it migrates into CS.
