"Multi-level storage system having a buffer store with variable mapping modes" (1972) mentions caching. The term doesn't require explanation in the paper so was obviously in reasonably wide use already https://patents.google.com/patent/US3820078A/en

"Sequel: A structured English Query language" (1975) https://dl.acm.org/citation.cfm?id=811515

"Vertical Migration for Performance Enhancement in Layered Hardware/Firmware/Software Systems" (1978) describes how to do live/live migrations behind load balancers. https://www.computer.org/csdl/magazine/co/1978/05/01646957/1...

All of these technologies is way older than you think.
