Sure, better hardware is always good! I would not say that the pressure is high. It’s just that for whatever thing the application is doing, there is a reasonable time to expect new requests. For a shopping cart let’s say ten minutes, for a game it depends on the rules but it can be precisely know generally. There is no reason to keep stuff alive beyond that time.
But I see you clearly are on the “let everything alive” side. It’s true that it is better as it is more simple. It would be possible to monitor resources globally and shut down processes from outside when reaching a specific limit.
