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 R5B memory-optimized instance family, generally available since December 1, 2020, features the Intel Xeon Platinum 8259CL processor. These instances do not offer local instance storage (EBS-only) but are specifically engineered for superior network-attached storage performance. R5B is distinguished by providing up to 60 Gbps of dedicated EBS bandwidth and 260K IOPS, a 3x increase over R5 instances. Powered by the AWS Nitro System, it is ideal for large relational databases and memory-intensive workloads requiring high EBS throughput.

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).
