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 C9g instance family, generally available since June 30, 2026, features custom-designed AWS Graviton5 processors built on the Arm Neoverse-V3 architecture. These compute-optimized instances do not include local instance storage, relying instead on Amazon EBS for block storage. They provide up to 100 Gbps of network bandwidth and up to 72 Gbps of EBS bandwidth, featuring ultra-fast DDR5 8800MT/s memory and the AWS Nitro Isolation Engine for mathematically proven VM isolation.

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).
