> if your using the right services, if someone asked you tomorrow to scale 100x you likely could during the workday.
"The right services" is I think doing a lot of work here. Which services specifically are you thinking of?
- S3? sure, 100x, 1000x, whatever, it doesn't care about your scale at all (your bill is another matter).
- Lambdas? On their own sure you can scale arbitrarily, but they don't really do anything unless they're connected to other stuff both upstream and downstream. Can those services manage 100x the load?
- Managed K8s? Managed DBs? EC2 instances? Really anything where you need to think about networking? Nope, you are not scaling this 100x without a LOT of planning and prep work.

You're note getting 100x increase in instances without justifying it to your account manager, anyway, long before you figure out how to get it to work.
EC2 has limits on the number of instances you can request, and it certainly won't let you 100x unless you've done it before and already gone through the hassle to get them to raise your limits.
On top of that, it is not unusual to hit availability issues with less common instance types. Been there, done that, had to provision several different instance types to get enough.
I hit it quite frequently with a particularly popular eks node instance type in us-east-1 (of course). I’m talking requesting like 5-6 instances, nothing crazy. Honestly, I wonder if ecs or fargate have the same issue.
