Map tiles are actually one thing you can still justify bare-metal for, imo. I don't do things with maps professionally but when I did some non-profit stuff involving maps in the last couple of years it didn't take long to figure out that RAM costs made cloud hosting/serving of maps prohibitively expensive, whereas doing it on bare metal with NVME disk arrays was a whole lot more feasible.
You don't need RAM to serve map tiles: Tilemaker and similar can produce the tiles to be served as static files. You can also find pre-made tile sets you can serve.
