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 R8ib instance family, generally available since April 16, 2026, features custom Intel Xeon 6 processors (Granite Rapids) such as the 6975P-C with a sustained all-core turbo frequency of 3.9 GHz. Built on the AWS Nitro System v6, these memory-optimized instances provide up to 100 Gbps of networking and enhanced EBS bandwidth for high-performance block storage. They lack local instance storage and are specifically designed for mission-critical, memory-intensive workloads like large-scale databases and real-time analytics requiring superior I/O throughput.

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).
