c6a.12xlarge pricing and specs in Asia Pacific (Mumbai)

48 vCPU · 96 GiB · 18.75 Gigabit · AMD EPYC 7R13 Processor

$1.1220/hour on-demand · $819/month (Linux, Shared)

c6a.12xlarge is a compute-optimized EC2 instance with 48 vCPU and 96 GiB, generation 6 of the c family. On-demand it costs $1.1220 an hour, about $819 a month if it runs all month. A one-year commitment with nothing up front works out at $0.7429 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 $0.4430 an hour, 61% below on-demand. The newer c6g.12xlarge offers the same size for $1.0224 an hour, 9% less and moves to Graviton. Asia Pacific (Mumbai) is already the cheapest region for c6a.12xlarge.

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.
