● Cloud disks are expensive.
● Long retention workloads TCO can
be 80% disk cost even at low
throughput
● EBS vs instance storage doesn’t
matter
○ double/triple replication
expensive compared to S3

EBS (GP2) $0.1/GiB pre-replication
EBS (GP2) $0.3/GiB post-replication
S3 $0.02/GiB post-replication
Why Tiered Storage?
Retention
