Isn’t Aurora horizontal by default?
EDIT: Here's what I was thinking about. It's chunked in 10gb increments that are replicated across AZs.
> Fault-tolerant and self-healing storage
Aurora's database storage volume is segmented in 10 GiB chunks and replicated across three Availability Zones, with each Availability Zone persisting 2 copies of each write. Aurora storage is fault-tolerant, transparently handling the loss of up to two copies of data without affecting database write availability and up to three copies without affecting read availability. Aurora storage is also self-healing; data blocks and disks are continuously scanned for errors and replaced automatically.
