Region disclaimer: default US East (N. Virginia) — prices vary by region. MVP = ElastiCache Serverless for Valkey only. Valkey: storage $0.084 / GB-hour; compute $0.0023 / million ECPUs; minimum metered storage 100 MB. Compare-note: Redis OSS / Memcached Serverless = $0.125 / GB-hour + $0.0034 / M ECPU, min 1 GB. ECPU: simple GET/SET ≈ 1 ECPU per KB transferred (min 1). Steady GB × 730 hours → monthly. AWS Example 1 style: 10 GB + 180M ECPU/hr → ~$1.254/hr ≈ ~$915/mo (switch ECPU mode to “per hour”). Out of MVP: on-demand node SKU matrix, reserved nodes, backups $0.085/GiB-mo (one-liner), cross-AZ transfer, Global Datastore / data-tiering.

How it works
- What does ElastiCache Serverless Valkey cost?
- In US East (N. Virginia): storage $0.084 per GB-hour and compute $0.0023 per million ECPUs, with a 100 MB minimum metered storage (as of 2026-11-03). Prices vary by region.
- How do I reproduce AWS Example 1?
- 10 GB steady + ~180M ECPU/hour → 10×$0.084 + 180×$0.0023 ≈ $1.254/hour ≈ $915/month (×730). Switch ECPU input mode to “per hour” and enter 180000000.
- How are ECPUs counted?
- For simple GET/SET, about 1 ECPU per KB transferred (minimum 1). Enter requests × avg KB, or paste ECPUs directly.
- Is Redis OSS / Memcached included?
- As a compare-note only: $0.125/GB-hour + $0.0034/M ECPU, min 1 GB. Primary path is Valkey Serverless.
- Does Serverless scale to zero?
- No — you still pay the GB-hour floor (min 100 MB on Valkey) even when traffic is idle-ish. Node-based RI, Global Datastore and data-tiering are out of MVP; backups note $0.085/GiB-mo.
