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 R5ad instance family, generally available since March 27, 2019, features AMD EPYC 7571 processors and offers configurations with up to 96 vCPUs and 768 GiB of memory. These memory-optimized instances provide up to 3600 GB of local NVMe SSD instance storage for fast temporary data caching and scratch space. They also deliver up to 20 Gbps of network bandwidth and up to 13.57 Gbps of EBS bandwidth, making them well suited for in-memory databases, distributed caches, and data analytics.
