Per hour on Windows, 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 R6A family, generally available since July 19, 2022, features 3rd Gen AMD EPYC 7R13 (Milan) processors with an all-core turbo up to 3.6 GHz. Built on the AWS Nitro System, these instances offer up to 50 Gbps enhanced networking and 40 Gbps of EBS bandwidth. They are SAP-certified and designed for memory-intensive workloads, supporting AMD TSME for always-on memory encryption. The largest and metal sizes also support Elastic Fabric Adapter (EFA) for low-latency communication.
