+  sizing_guidance: |
+    1. Determine required IOPS (from AWR, CloudWatch, or application benchmarks)
+    2. Select tier that provides needed IOPS/GB ratio
+    3. Calculate minimum volume size: required_iops / iops_per_gb
+    4. Ensure volume size also covers storage capacity needs
+    5. If capacity-driven size exceeds IOPS needs, lower tier may suffice
+

+    - name: "Standard"

+  auto_tiering: |
+    Enable auto-tiering to automatically move objects between Standard and
+    Infrequent Access based on access patterns. No retrieval fee when
+    auto-tiering moves data back to Standard.
