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 C5A instance family, generally available since June 4, 2020, is powered by custom 2nd Generation AMD EPYC 7002 series processors (AMD EPYC 7R32) running up to 3.3 GHz. These compute-optimized instances provide up to 20 Gbps of network bandwidth and up to 9.5 Gbps of dedicated EBS bandwidth. C5A instances do not have local instance storage, but their C5AD variants feature local NVMe SSDs.

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 Windows, 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).
