We believe people tend to opt for the less complex solution over time. This evolution happens slowly and may upset many people but in the end, simplicity wins. Caching, SQL, Load Balancers didn't exist a few decades ago and now we spend months of our limited time trying to tame the cloud machine.

Don't get me wrong, I'm a lover of (complex) systems, but not everybody needs them/can maintain them.

Edit: couple => few

"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.

Thank you for the very useful links.

Caching, SQL and Load Balancers definitely existing a couple of decades ago...

Edit: Regarding your edit to "few", 40-50 years (at least) isn't a few.
