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 R5A memory-optimized instance family, first available in November 2018, features the AMD EPYC 7000 series processor (EPYC 7571) with an all-core turbo of up to 2.5 GHz. These instances are EBS-only, meaning they do not offer local NVMe instance storage. They provide up to 10 Gbps of network performance and are powered by the AWS Nitro System. R5A instances offer a cost-optimized alternative, with up to 10% savings over comparable R5 instances.

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).
