The real question: does this provide a faster elasticity component than ELBs?

At a previous employer, we punted on ever using ELBs at the edge because our traffic was just too unpredictable.

Combining together all of the internet rumors, I've been led to believe that ELBs were/are custom software running on simple EC2 instances in an ASG or something, hence being relatively slow to respond to traffic spikes.

Given that ALBs are metered, it seems like this suggests shared infrastructure (binpacking peoples ALBs onto beefy machines) which makes me wonder if that is how it actually works now, because it would seem the region/AZ-level elasticity of ALBs could actually help the elasticity of a single ALB.

If you don't have to spin up a brand new machine, but simply configure another to start helping out, or spin up a container on another which launches faster than an EC2 instance... that'd be clutch.

Deep thoughts?
