Per hour on Linux/UNIX, in each type's cheapest region. Typical spot: per pricing run of the last 7 days, the cheapest zone's spot price, averaged, as the finder shows it with that region selected. On-demand: the same region's price. Per vCPU-hour: the spot price, or without spot the on-demand price, per vCPU. Every region is under Prices by region.

The M8I-FLEX family, generally available since August 28, 2025, features custom Intel Xeon 6 processors with a sustained all-core turbo of 3.9 GHz. These general-purpose instances, a cost-optimized M8i variant, do not include local instance storage and are EBS-only. They offer up to 30 Gbps of networking and 20 Gbps of EBS bandwidth, with 2.5x more memory bandwidth than M7i-flex. They are designed for workloads that do not continuously utilize all compute resources but benefit from the latest performance.

Network and EBS: peak bandwidth in Gbit/s, with the bandwidth the type sustains when it is lower. Local storage: the instance store, in decimal GB as AWS sizes it.

Atom feed for new regions

Each type's regions on Linux/UNIX, cheapest first, with the same figures as the Prices table, and its price history: the daily mean of every zone and pricing run, over the last 15 UTC days. Each price column is tinted from its cheapest region (green) to its most expensive (red).
