c6g.large

Analysis

The c6g.large is a compute optimized instance in the c6g series with 2 vCPUs and 4 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 $45.41 a month per instance: $0.0426/hour against $0.1048/hour, a 146% spread.

At $0.0680/hour on demand in US East (N. Virginia), about $49.64 a month, the c6g.large 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 5 processor variants AWS sells at this size and generation. The c6gn.large on AWS Graviton2 costs 27% more, and the c6a.large, the c6gd.large and the c6i.large also sit above it.

The newer c7g.large on AWS Graviton3 is 6.6% dearer at $0.0725/hour.

Looking beyond its own line, 5 of 36 current types with 2 vCPUs and similar memory are cheaper. The cheapest of those is the t4g.medium on AWS Graviton2 at $0.0336/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 $0.0428/hour, which beats on demand once it runs more than 63% of the time; three years brings it to $0.0294/hour, 57% below on demand.
