Term	Kind	Topic	What it is
Block Storage Persistent Disk, EBS	concept	Cloud Storage	A virtual disk attached to one instance at a time, presented as raw blocks and formatted with a filesystem — the storage databases and stateful workloads run on.
Durability vs Availability	concept	Cloud Storage	Two different storage guarantees — whether data survives, and whether it can be reached right now — routinely conflated because both are quoted in nines.
