r6a.8xlarge pricing and specs in Asia Pacific (Mumbai)

32 vCPU · 256 GiB · 12.5 Gigabit · AMD EPYC 7R13 Processor

$1.1440/hour on-demand · $835/month (Linux, Shared)

r6a.8xlarge is a memory-optimized EC2 instance with 32 vCPU and 256 GiB, generation 6 of the r family. On-demand it costs $1.1440 an hour, about $835 a month if it runs all month. A one-year commitment with nothing up front works out at $0.7518 an hour and pays for itself above roughly 479 hours a month; below that, on-demand is cheaper. The three-year options go down to $0.4516 an hour, 61% below on-demand. The newer r6g.8xlarge offers the same size for $1.0400 an hour, 9% less and moves to Graviton. Asia Pacific (Mumbai) is already the cheapest region for r6a.8xlarge.

Newer generations of the same size

Same family letter and size in a newer generation, ranked by price. “vCPU per $” uses vCPU as the performance proxy — newer chips usually add more, so it is a floor.
