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 C8ib instance family, generally available since April 2025, features Intel Xeon 6975P-C (Granite Rapids) processors designed for high-performance compute workloads. These instances provide up to 200 Gbps of networking bandwidth and enhanced EBS performance of up to 100 Gbps to ensure low-latency access to block storage. As EBS-optimized instances without local storage, the C8ib family is specifically engineered for compute-intensive applications such as batch processing, video encoding, and large-scale distributed analytics.

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).
