c6a.8xlarge pricing and specs in Asia Pacific (Mumbai)

32 vCPU · 64 GiB · 12.5 Gigabit · AMD EPYC 7R13 Processor

$0.7480/hour on-demand · $546/month (Linux, Shared)

c6a.8xlarge is a compute-optimized EC2 instance with 32 vCPU and 64 GiB, generation 6 of the c family. On-demand it costs $0.7480 an hour, about $546 a month if it runs all month. A one-year commitment with nothing up front works out at $0.4953 an hour and pays for itself above roughly 483 hours a month; below that, on-demand is cheaper. The three-year options go down to $0.2953 an hour, 61% below on-demand. The newer c6g.8xlarge offers the same size for $0.6816 an hour, 9% less and moves to Graviton. Asia Pacific (Mumbai) is already the cheapest region for c6a.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.
