Economics of using Local Storage Attached to VMs on Cloud Providers [I]
summary
Compares AWS/GCP block (EBS) vs instance store and object options, claiming local instance SSDs deliver ~10x IOPS at roughly 1/10th the cost but sacrifice cross‑AZ durability; demonstrates building local storage pools with Kubernetes + Rook and shows 3‑way replication across nodes, automatic rebalance and lifecycle management working end‑to‑end. Covers caveats: system disk misuse, lost data when instances fail or move zones, and rough throughput numbers (3–5 Gbps per instance) used for sizing.
