Analysis
The c6a.48xlarge is a compute optimized instance in the c6a series with 192 vCPUs and 384 GiB of memory on AMD EPYC 7R13 (up to 3.6 GHz), which makes it compute-heavy at 2 GiB of memory per vCPU.
The newer c7a.48xlarge on AMD EPYC 9R14 is 34% dearer at $9.85/hour.
Running it in Mumbai instead of São Paulo saves $4,986 a month per instance: $4.49/hour against $11.32/hour, a 152% spread.
Nothing else with 192 vCPUs and similar memory is cheaper: among 14 current same-shape types it has the lowest on-demand price.
At $7.34/hour on demand in US East (N. Virginia), about $5,361 a month, the c6a.48xlarge is one of the cheaper ways to buy compute optimized capacity: only 8% of the 291 current compute optimized types cost less per vCPU-hour than its $0.0382.
Reserving it for a year with no upfront payment cuts the Linux rate to $4.86/hour, which beats on demand once it runs more than 66% of the time; three years brings it to $3.23/hour, 56% below on demand. Windows Server roughly doubles the bill at $16.18/hour, because the licence is charged per vCPU.
It is the largest of the 10 c6a sizes. Dropping to the c6a.32xlarge saves $1,787 a month.
