I wonder how the cost differs, given they have to keep hot standbys? Perhaps a lot of behind-the scenes prediction to make it cost effective? Takes a while to create a standby from scratch for large DBs.

Either way, sweet tech. Seems like a fun thing to build

Aurora doesn’t work that way - it has one storage layer shared by all the nodes. Adding a new replica is very fast no matter your data set size.

Cool... but.. how?

Aurora already spreads each "10GB chunk of your database volume is replicated six ways, across three Availability Zones." It looks like from the diagram they are taking advantage of that fact and spinning down the instances that serve off those "disks"

Ahh, makes sense. Thanks for the clarification there!
