c6g.medium

Analysis

The c6g.medium is a compute optimized instance in the c6g series with 1 vCPU and 2 GiB of memory on AWS Graviton2 (up to 2.5 GHz), which makes it compute-heavy at 2 GiB of memory per vCPU.

Running it in Mumbai instead of São Paulo saves $22.70 a month per instance: $0.0213/hour against $0.0524/hour, a 146% spread.

At $0.0340/hour on demand in US East (N. Virginia), about $24.82 a month, the c6g.medium is one of the cheaper ways to buy compute optimized capacity: only 2% of the 291 current compute optimized types cost less per vCPU-hour than its $0.0340.

It is the cheapest of the 3 processor variants AWS sells at this size and generation. The c6gn.medium on AWS Graviton2 costs 27% more, and the c6gd.medium also sit above it.

The newer c7g.medium on AWS Graviton3 is 6.8% dearer at $0.0363/hour.

Looking beyond its own line, 1 of 15 current types with 1 vCPU and similar memory are cheaper. The cheapest of those is the t2.small on Intel Xeon Family at $0.0230/hour. It is burstable, so it only suits workloads that do not run the CPU flat out.

Reserving it for a year with no upfront payment cuts the Linux rate to $0.0214/hour, which beats on demand once it runs more than 63% of the time; three years brings it to $0.0147/hour, 57% below on demand.
