Are you sure there’s a significant difference between RISC and CISC after instructions are decoded?
The assembly in RISC is just an abstraction of the machine code, as it also is in CISC. If the underlying CPU has the same capabilities then it doesn’t really matter what the assembly looks like?
Of course, the underlying CPUs aren’t the same and that’s the real point of differentiation.

“Global” services like CloudFront and Route53 are really us-east-1 under the hood with replication to other regions.
