I'm pretty sure that AWS' service quotas exist more as a guardrail to prevent customers from accidentally spinning up 1000 instances instead of 10, which would not only leave you with an eye-watering bill, but affect resource availability for other customers.

They're usually quite happy to increate the quote if you contact support.

Most limits exist within what AWS has determined is 'normal' usage. Once you pass that, you can request a service limit increase.

Service limit increases are typically only denied when raising the limit would negatively impact the availability of the service (noisy neighbor issues, for example), or if the customer is needing a limit increase because they're trying to use the service in a way it wasn't designed.
