I'm a bit confused; I thought Server Load Balancer also helps with scaling, but it seems more focused on traffic distribution.

This one seems pretty straightforward. I think the purpose of an Architecture Compliance review is to evaluate the readiness of the organization to undergo change, so I'll go with option C.

Ugh, I'm not sure about this one. The prefixes and exponents for the different units are tripping me up. I better review my notes on Ethereum's unit system.

I guess the ECS instances are on auto-pilot with this 'Auto Scaling' feature. They just need to make sure the seatbelts are fastened when the load gets bumpy!
