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 memory-optimized R7IZ instances, generally available since September 7, 2023, feature 4th Generation Intel Xeon Scalable processors (Sapphire Rapids) with a 3.9 GHz sustained all-core turbo frequency. These high-frequency instances deliver up to 50 Gbps of networking and 40 Gbps of EBS bandwidth, utilize DDR5 memory, and are EBS-only for storage, making them ideal for high-performance databases and EDA workloads.

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).
